Women in ACR? I’ve been the industry now for just over 12 years – where has that gone?!! One thing which has become prevalent is the increase of women in the forefront. From rolling up their sleeves installing & maintaining to training, specifying, marketing, selling and major decision making. The ACR Journal are proud to be recognising so much of the excellent work and standards that women in the ACR industry are providing. (Turn to pages 46 & 47 for this month’s feature with Lisa Woodcock from Oceanair).

We’ve been running the ‘Women in ACR’ section for nearly a year now. Out of some of the interviews with Directors, Engineers, Trainers, Marketers, and Sales Managers, one thing keeps coming to the forefront; how they came to the industry in the first place. Not surprisingly, most had been introduced by family; uncles, fathers, brothers and partners.

I believe this commonality is unique to the industry as a whole. Whilst this does help in creating some loyalty it also begs the question “are we able to consistently recruit enough quality and quantity”

Recruitment and training has always been a hot topic. We need to recognise the hard work many manufacturers and training companies have done to extend this reach. Going into schools and setting up schemes to ‘awaken’ youngster’s opportunities is not an easy task but, one that can only benefit the industry as whole. In fact, the IOR are taking refrigeration to the school room from September this year. (more info on Page 10)

Tell us about your efforts in encouraging a greater awareness to the next generation of apprentices in ACR.

We, at ACR support training so much that we run the ‘Not for Profit’ ACR Trainee of the Year Awards (TOTY) every December. All excess funds are reinvested back into training via the apprentices and the training providers who put them forward. (If you as an individual or as a company, have an apprentice worthy of recognition then visit page 8 for further info).

Aspen Pumps Invests in Australian HVAC Distributor

New President for FETAGraham Wright becomes FETA president and emphasises the important role of FETA as the voice of the industry

At the end of July, 2015 Graham Wright of Daikin took up the role of FETA President for the next twelve months. He believes the Federation plays a very important part in the building services sector, which is faced with a raft of new and challenging legislation and targets.

“FETA brings together several diff erent areas connected to building services – from heating and ventilating to refrigeration, ductwork, fl ues and controls. It can therefore be a voice on the key issues aff ecting this broad sector,” said Mr Wright.

He also highlighted the fact that the industry must deal with a raft of legislation coming from Europe, including F Gas and the Energy Related Products Directive (ErP).

“FETA can work within European groups to help UK companies understand what legislation is coming our way. It can also put forward the UK view to Europe on these issues as they develop,” adds Mr Wright.

Graham Wright is a mechanical engineer with thirty years’ experience in the air conditioning industry. In his current role as Legislation Specialist for Daikin UK, he reviews existing and pending EU and UK legislation for the heating and air conditioning sectors.

“Dean & Wood opened the doors to a new branch in Canning Town London. The enthusiastic and experienced team is ready to serve both existing customers and new”

Condensate pump experts, Aspen Pumps announced that it has invested in Australian heating, ventilation and air conditioning (HVAC) equipment distributors, Pro Pipe Supplies.

Pro Pipe started in 1999 as a niche supplier of high quality refrigeration drain pipes. It is now one of the main companies in the Australian HVAC market. Aspen Pumps has a long history with the company started by owners and founders, Brett Spicer & Bob Babidge.

Aspen Pumps CEO Adrian Thompson said:“We are delighted to announce that we have formed a closer relationship with Pro Pipe, a leading HVAC distributor in Australia. This transaction represents an important step in delivering on our strategy of accelerating international growth.”

“Pro Pipe was the obvious choice for us to expand our presence in the Australasian region; we have long standing partnerships with the business and it shares Aspen’s core values of quality products, supported by excellent customer service and strong relationships. We look forward to working even closer with the

team and supporting them in achieving their growth plans.”

3i invested in Aspen Pumps in February 2015 and Pro Pipe is the condensate company’s fi rst investment since then. The

move marks Aspen’s plans to grow its business around the world.

AC TEMPERATURES

Is this why women wear their coats in the office?

Colin Fernandez, Science Correspondent for the Daily Mail looks into why and what we need to do about it.

When you’re maintaining or servicing air conditioning systems, do your clients say their office is a constant battle ground over the air conditioning? Scientists may have worked out why!

Workplaces could be too cold for women because temperature levels are based on the preferences of a middle-aged male. It means many women could be working in conditions several degrees cooler than they would like – and could explain why so many end up wearing their coats at their desk.

Current air conditioning standards are the result of research from the 1960s, which used a standard ‘metabolic rate’ to work out a comfortable working temperature. Metabolic rate is the speed at which our bodies burn energy, and is key to how much heat we generate.

But, the study was based on the values for a 40-year-old man – whereas women have a rate that is typically 35 per cent lower. Now researchers from Maastricht University in the Netherlands say that women do indeed prefer warmer working temperatures, favouring a room of 25°C (77°F) compared with 22°C (72°F) for men.

They analysed 16 young women performing light office work, and found they required considerably less cooling than current air conditioning guidelines suggest. The study authors have now called for standard settings to be altered to take gender differences into account.

Current air conditioning standards are the result of research from the 1960s, based on the values for a 40-year-old man. ‘Therefore current indoor climate standards may intrinsically misrepresent thermal demand of the female and senior populations,’ the scientists said. ‘Comfort models need either to be recalibrated or enhanced using a biophysical approach.’

Air conditioning temperatures are based on the preferences of a middle-aged male!

Writing in the Journal Nature Climate Change, Dr Boris Kingma and Professor Wouter van Marken Lichtenbelt said: ‘Thermal comfort models need to adjust the current metabolic standard by including the actual values for females.’ They added that metabolic rate also lowers with age, meaning older employees could equally be feeling the chill.

The site is fun and attractive with

animations, graphics and videos designed to engage young learners and keep them coming back to improve their gaming scores. They can even log in via Facebook and post their scores to their own Facebook page! The site also links to other related refrigeration and air-conditioning resources for schools and young people like Cool Science at the Big Bang Fair and the IOR’s own Careers in Cooling video.

It features games such as “Does it need refrigeration?”, “The Phase Change drag and drop game” and “The Fridge circuit test?”. There are also illustrated slide shows about the cold chain, the history of refrigeration and food processing, featuring links to short videos.

This new site was tested and trialled by teachers and children over the summer and will be promoted strongly to schools and careers services from September. It will help to encourage awareness and interest in refrigeration and provide a fun way to learn about how scientifi c principles such as changing states of matter and pressure temperature relationships are applied.

If you want to take a look at the site or pass the link to any schools and young people you know please visit

www.fantasticfridges.org. We will be using social media and science, engineering and technology networks to raise awareness of this

important new resource – so watch out for more news and links when this goes live, and help pass the message on.

The IOR’s Presidents’ Fund has paid for the development work involved in this project. Which is the fi rst stage of the new site to be developed. It was based on material originally put together for the IOR Centenary schools project, updated and simplifi ed for a new audience. The new site is focused on “Young Learners” but the content for additional sections on “Cooling Science” and “Advanced Topics” are currently under development.

The Institute is looking for companies or individuals who would like to help contribute to fund raising activities to help cover the costs of producing new higher-level games and animations. It is proposed that the new section on Cooling Science

will have content more suitable for those with some knowledge of refrigeration engineering students or technician.

The fi nal section on Advanced Topics will be particularly aimed at those working in the industry at the moment who want to learn more about the science behind advancing technologies such as compressor developments or carbon dioxide refrigeration systems.

Whilst the current Fantastic Fridges website is very much about teaching children that refrigeration is interesting, the new sections will fi t more closely with the work that the Institute is doing to support its members in areas such as apprenticeship development, leakage reduction and learning about alternative refrigerants and systems.

If you would like to be involved in supporting the next stage of development of the project please contact the IOR on

September 2015

Representatives from colleges, employers, end users, training providers and industry associations discussed

training for the future.Top of the agenda was news of the new Refrigeration

Air Conditioning and Heat Pump Engineering Technician Apprenticeship. It comes under the government’s new employer-led Apprenticeship Trailblazer scheme.

A steering group agreed on a new apprenticeship standard for our sector in February.

ACRIB is waiting for government response to the proposals. Once fi nalised, organisations will develop qualifi cations to help training companies and colleges prepare for the new Apprenticeships. Work should start in September 2016.

The new Apprenticeship will focus more on the scientifi c theory and underpinning principles needed to work in any area of the industry. The Apprenticeship will be a three year level 3 standard. Level 2 and 3 qualifi cations which link to the new qualifi cation should come onto the market.

The fi nal apprenticeship exam will contain practical work in the college, a review of a work place evidence and an online theory. Grades for the qualifi cation are Pass, Merit and Distinction. Apprentices passing the exam will have enough to apply for Engineering Technician registration with the Engineering Council.

Other areas discussed included:₀ How the existing apprenticeships could link across to the

new scheme₀ The need for short course CPD units for the existing workforce to

update their skills.₀ Confi rmation of inclusion of F Gas certifi cation within qualifi cations

for apprenticeshipsCity & Guilds and ACRIB are working together to provide more

support for the training provider network. The group discussed whether UK could continue to fi eld a candidate

for World Skills competitions and national SkillFRIDGE events. Employers and candidates benefi t from past involvement and the high levels of training to prepare for the events. They also provide a good profi le raising opportunity for recruitment. But, the events had now lost funding from SummitSkills and are struggling to fi nd resources to continue. Industry groups and colleges agreed to support them with promotion and encouragement wherever possible.

Some recent educational successes include free e-learning on alternative refrigerants and refrigerant containment available from the Institute of Refrigeration at www.realalternatives.eu and www.realzero.org.uk

Cool Science displays and interactive sessions at the Big Bang Science fair in February.

1212TECHNICAL PANEL12


So hopefully everyone in the industry has work coming out of their ears and cannot fi nd enough

hours in the day to cope with demand.But we all know what a fi ckle mistress the British weather is and

for those whose air conditioning business is constantly reliant on the vagaries of the seasons, is there a way of ensuring more consistent business throughout the year?

Do you suff er from a slump in business in the colder months of the year?

Do you want another way to use your F-Gas skills and diff erentiate yourself from the competition?

Is it time you thought seriously about getting into heating?Before you all scream that you are not set up to cope with

consumers and plumbing, let me point out that BSRIA predicts a healthy growth in demand for air source heat pumps both in domestic and commercial situations.

Can I also highlight the fact that in addition to ‘monobloc’ ASHPs,

there is a real place for split systems – which can only be fi tted by F-Gas qualifi ed engineers!

Whilst monoblocs off er a straightforward way for many homes and businesses to access renewable heating, split systems have many advantages because the ability to site the outdoor unit further away from the building than a monobloc can help with design.

In addition to this, the fact that splits also use refrigerant piping between the outdoor and the indoor also means that they do not rely on a glycol solution – which some people prefer.

Having the skills necessary to install a split system for heating and hot water can therefore off er a real business opportunity for installers ready to engage with both businesses and consumers looking for expertise and advice on the best renewable system to install.

There are plenty of training opportunities available between now and the time when the cold weather starts to threaten, so doesn’t this off er a real opportunity for business growth for F-Gas engineers when everyone has forgotten the heat of the summer?

Why summer may be the best time to think of heating by Ben Bartle - Ross, Technical Trainer

At the time of writing, Britain has just had its hottest July day on record and this has to be good news for the air conditioning industry, which seems to naturally grow every time a scorching British summer makes people think seriously of the merits of air conditioning.

DATA CENTRE COOLING14

ENERGY IN DATA CENTRES The UK data centre market is estimated to consume around 6.4 GW of power annually – roughly enough energy to power six million homes. Industry fi gures suggest this will continue to rise as the demand for data centre services becomes ever more important.

To meet higher demands, data centre operators are adopting higher-density servers, resulting in increased power consumption and heat generation, which in turn requires more power for cooling.

Power consumption is now a major consideration for today’s data centres, with operators continually striving to enhance energy effi ciency, reduce their power consumption, reduce their operating expense and reduce their environmental impact.

“Energy savings up to 50 per centcan be achieved”

THE ENERGY CHALLENGES FACED BY

HOW DATA CENTRES CAN REDUCE THEIR ENERGY CONSUMPTIONCooling is one of the most important considerations for data centres, as it accounts for around half of all electrical energy consumed. Therefore, optimising the cooling effi ciency should be one of the highest priorities for data centre providers and facility managers, especially those in charge of legacy data centres.

Legacy data centres will often have ineffi cient cooling equipment such as, Computer Room Air Conditioning (CRAC) units and chillers that use AC fans. In the case of CRAC units, these use mainly belt driven forward curved fans running at a fi xed speed. Ineffi cient CRAC units can be upgraded by replacing the original AC fans with high effi ciency EC backward curved fans. In addition to having more effi cient motors, EC fans have simple speed control settings which can off er further energy savings.

Upgrade projects have shown that energy savings of around 50 per cent can be achieved on CRAC units simply by replacing the AC fans with EC fans, with additional savings of a further ten to 20 per cent by reducing the fan speed. The energy savings not only have a signifi cant fi nancial benefi t –

with a typical payback period of less than two years – but also result in reduced CO emissions, reduced maintenance and increased capacity.

EBM-PAPST’S EXPERIENCEebm-papst develops energy effi cient fans and provides energy effi cient solutions for data centre cooling. This work has provided signifi cant energy savings on legacy data centre equipment.

ebm-papst UK has collaborated with ICT infrastructure experts Emerson Network Power and facilities management providers Norland Managed Services to review energy effi ciency at a well-known bank’s London-based data centres, and then project managed the EC upgrades.

The initial site survey and review found the centres’ existing cooling units ran using nearly 200 AC driven fans, each with only basic settings. It was obvious that EC technology could make a huge diff erence and two diff erent units were trialled to demonstrate how the EC units consumed less power.

Following a successful trial, the data centres were upgraded with 76 new CRAC units of varying models (containing 191 fans in total) in a live data environment. The bank’s projected annual

DATA CENTRE COOLING16


energy savings now range between £240,000 and £270,000, with the upgrade bill set to be paid off by the end of 2015.

Other projects that ebm-papst has overseen includes large-scale data centre air conditioning upgrades for a telecoms provider that saw its data centre energy consumption slashed by 78 per cent and £185,000 saved on its annual energy bill.

VOLUNTARY INITIATIVES BUT NOTHING SET IN STONEThe EU has appointed advocates for energy saving protocols in data

centres, with ebm-papst being named as an offi cial endorser of its Code of Conduct for Data Centres. The code is a growing voluntary initiative, which recognises the eff orts of big business across Europe to measure and reduce the energy consumption of their IT equipment and auxiliary systems.

There are currently around 200 participating data centres registered on the scheme, belonging to 73 individual participants, including many IT and communications giants. However, there is still the scope and capability to get more businesses, of varying sizes, involved and proactively modifying their data centres.

This voluntary initiative is helping data centres, but there is still a lack of genuinely clear international standards for data centres. This was one of the main points discussed at our data centre seminar in August last year, with data centre expert Mark Acton from Norland Managed Services warning UK data centre managers that they need to be aware of ongoing work to standardise the sector or risk getting caught out by new laws and penalties.

THE FUTURE OF DATA COOLINGIS IN OUR HANDSLarge data centres are becoming more common in today’s era of digital information and recording, so ensuring that IT equipment is kept in optimum operational conditions is of vital importance.

It’s fair to say that the UK data centre industry is still falling behind when it comes to monitoring energy effi ciency and adopting energy saving technologies. However, it is becoming increasingly aware of the benefi ts of energy effi cient cooling, and how to use energy more effi ciently is now fi rmly on the agenda for most data centres.

So, while the amount and size of data centres might be mushrooming, energy consumption doesn’t have to. Our own work has shown that energy savings can be possible without a complete refurbishment of data centres costing hundreds of thousands. Businesses can reap serious cost savings simply by reviewing data centre energy usage, updating to modern sustainable EC cooling fans and then controlling these new fans so they are even more effi cient.

LG SPECIAL18


L G’s UK Head of Air Conditioning and Energy,

Jody Lees, invited me out to Korea to see how they operate. The group consisted of Consultants from Buro Happold, Mitie, JCW Energy Services, North Bristol NHS and Bublshop.

The air conditioning market is as about as competitive as it gets in the UK. To compete against the

ACR Journal editor, Will Hawkins, spent a week in South Korea with LG learning about what makes this company so impressive.

manufacturers with the biggest market shares, you have to have a clear strategy. You need great products, great service and top people in place to stand a chance of being successful.

GROWTH FROM CHANGEJody has had a big impact on LG’s fortunes in the UK. Since arriving at the company, a few years ago, sales have increased. LG is the fastest growing air conditioning brand in the UK (according to Jody). A combination of changes in the business has made LG’s growth possible.

The fi rst change made was getting the right team in place. He recruited a strong team of sales and marketing experts. They have the right attitude, skills and experience to put Jody’s master plan in place.

Next, LG brought its products up to speed to be able to compete. That is testament to his work with LG’s UK Product Manager, Steve Jung. The pair worked hard to bring the LG product range up to a standard suitable to the UK market. Customers can take LG seriously.

Jody explained that he has made subtle changes in his approach to developing future business in the UK. In a market which thrives

on its strong relationships, LG’s engineers work more with customers early in the design process. It’s a popular approach.

WORKING CLOSELY WITH CUSTOMERSThe engineers help their customers’ commission and install their LG products. This ensures they works as designed. It seems like an obvious approach, but strategy seems to be working. Such a simple change of tack has improved LG’s business.

The team now receives ‘inbound’ leads from the referrals the ‘hands-on’ approach generates.

Jody explained how the European subsidiaries now store their stock in the Netherlands. This change has increased the speed at which they get units out to customers. If customers want it ‘next day’ in the UK they can buy it from the well-known air conditioning and refrigeration wholesalers. Jody has transformed LG’s service levels in the UK with the changes.

BIG ENOUGH TO COMPETEThe main LG factory is, as mentioned, in Changwon, a city near Busan, Korea’s second city. The fi rst to thing to strike you when you arrive at the LG factory is the sheer scale of it. The site is massive. It is not surprising, considering the number of air conditioning, heat pump and compressors units the company each day.

More interestingly (given the group’s focus on building services), we then went to see the factory where LG makes its Multi V IV VRF units. Like many factories in this part of the world, it operates on a LEAN basis. It rotates its workers around various tasks to keep them stimulated so they maintain the quality of its products.

“If there is one thing that today with LG showed me

about the company, it is its scale of capability.”

The factory is a mix of human operators and robots. Most of the robots are moving components around the fl oor. If you happen to get in their way, they pause, honk their horns and move on when clear. Each delivery robot is tracked around the factory to see when and where parts are delivered.

Along the production line are screens showing the targets for each shift. The factory builds around 200 units a day in the summer, seven days a week. Multi V IV units use R410A refrigerant. They launched in the UK in January 2014.

LG tests a percentage of the units coming off the production line for performance. Leak detection is also part of the production process. This ensures they know everything is up to the high standard it sets itself. In the testing centre, we also saw some of the products coming ‘down the line’. I am not able to tell you what they are, unfortunately. But, it

highlighted the speed at which LG develops its new products.

The indoor units are made upstairs in the factory where they make around 1,200 units a day. This increases in the summer.

We moved onto one of LG’s ‘dormitories’ for its employees in the town to see how it uses its own products.

The dormitory uses LG VRF, solar panels and high temperature heat pumps to provide heating and cooling. The boiler room contained LG air handling units too, with the Multi V IV outdoors units on the roof. It was an impressive installation.

Finally, we visited the air conditioning, heat pump and refrigeration showroom. On top of its well-known AC and air source heat pump systems, LG has geothermal, and water source heat pumps. The company also makes solar PV solutions andenergy effi cient retail refrigeration solutions.

SCALABILITYIf there is one thing that today with LG showed me about the company, is its scale of capability.

Having a massive factory is one thing. But, being able to handle big projects is another. To deliver large scale air conditioning projects, you not only need the volume of products to make it possible. You also need to have the technical skills to provide the solution.

LG took us to see a reference site which aptly demonstrated what LG is capable of delivering. In Busan, as you drive in from the airport, there is a group of high rise, luxury apartments which stand like sentinels guarding the city.

These glass-fronted buildings include the ‘Zenith Tower’, an 80-fl oor residential tower block. It is over 300 metres high and went up in 2011. It took four years to build and it has nearly 1,800 individual apartments. The Zenith Tower is the second tallest building in Korea.

LG provided the air conditioning systems, namely its Multi V III units for the entire building. Each apartment has its own LG system providing cooling. The Zenith Tower is an impressive project.

If you think that LG is a small player in the global air conditioning and heat pump market, think again. LG is big, capable and responsive to a fast-changing market.

21LEAK DETECTION

Early detection of refrigerant leaks has never been so

important. Whether it’s for safety due to fl ammability or to maintain, optimum energy effi ciency, minimise the cost of the refrigerant lost, or to comply with legislation such F-Gas, there has never been so many compelling reasons to fi nd leaks and fi x them early and quickly.

With the cost of a basic automatic leak detection system little more than the price of a 60kg bottle of refrigerant, and with the higher GWP refrigerants predicted to dramatically increase in price over

CO2 Tonnes equivalent value = Refrigerant charge in kg x GWP value of the refrigerant /1000₀ Any equipment containing 5 Tonnes CO equivalent or more needs to be leak checked

and documented, as required by Article 6 on record keeping.₀ For R-404A this is reduced to 1.3kg charge, R-410A to 2.4kg, although R-134a has

increased to 3.5kg.₀ For hermetically sealed systems the threshold doubled as it applies from 10 Tonnes

CO2 equivalent.₀ For systems with a charge of 3kg or less (6kg for hermetic systems), the leak check

requirements don’t apply until 1st January 2017.₀ For all other systems the new requirements are already in force.

Saving you both time & moneywhilst complying with legislation



the next few years, it would seem a shrewd investment, and one that would help users to comply with the new revised F-Gas legislation.

THE LEGISLATION SURROUNDING LEAK DETECTIONThe revised F-Gas 517/2014 legislation came into eff ect on 1st January 2015 placing greater importance on minimising refrigerant emissions and requiring more regular leak checks on many types of equipment.

Article 3 requires operators of equipment containing F-Gases to take precautions to prevent leakage

and take all measures, technically and economically feasible, to minimise leaks. Furthermore, they have to ensure equipment is repaired without undue delay. Many of the principles of the 2006 F-Gas legislation remain in Articles 4 and 5, but, equipment with higher GWP refrigerants will need to be checked for leaks much more frequently.

The refrigerant charge is no longer the reference point, instead it’s the CO Tonnes equivalent charge value. This is calculated by multiplying the charge in kg by the GWP value of the refrigerant in the system.

“fi xed leak detection is going to play an important part”

Climalife.indd 21 13/08/2015 12:42

REFRIGERANTS22



The frequency of leak checking is dependent upon the CO Tonnes equivalent value, with thresholds also at 50 and 500 Tonnes CO equivalent.

Those systems with automatic leak detection that alerts the operator do not need to carry out a leak check as frequently. The logic being that if a leak were to occur, fi xed leak detection would identify it immediately rather than waiting until the mandatory leak check.

For systems with 500 Tonnes CO equivalent or more, fi xed leak detection is mandatory. For R-404A this applies to anything with a charge of 127kg or more, whilst for R-407C it would be 282kg.

The incentive for fi xed leak detection is to minimise emissions and early detection of a leak starting to occur, which for high GWP refrigerants is particularly important.

LEAK DETECTION:SYSTEMS AND SENSORSLeak detection systemsThere are several diff erent types of leak detection systems available using diff erent sensing technologies. Point detectors have a sensor which is mounted at the probable point of a leak and have the advantage that every instrument continuously monitors the air at that location, resulting in much shorter response time. Aspirated systems sample gas via tubing from various locations to a central sensor and act as a complete centralised control system where the sampled air is evaluated within the system and all measure values are displayed in one unit.

Leak detection sensorsThere are a number of diff erent sensor technologies available for use in refrigerant leak detection systems. Semiconductor sensors (suited to HFCs, CFCs, HCFCs and propane) respond to a broad range of gases and are usually a lower cost option. Infrared sensors (suited to HFC, CFC, HCFCs, NH3 and CO2) and Electrochemical sensors (suited to NH3) are more gas-specifi c types and provide higher performance, enhanced accuracy and smaller detection limits.

HOW AND WHERE SHOULDYOU MONITOR?Chiller plants, refrigeration plants, cold stores and store fl oors should be monitored, so too should air conditioning systems to

ensure building occupant safety. There are a number of companies in the UK, such as Climalife working in partnership with Bacharach, who can advise on various leak detection solutions for a range of building needs and provide more tailored guidance around location of equipment, type and number of sensors to use.

LEAK DETECTION IS HERE TO STAYTo meet the F-Gas quota reductions on the amount of refrigerant that can placed on the market each year, fi xed leak detection is going to play an important part in reducing leaks and will be very cost eff ective as refrigerant prices escalate, particularly those with higher GWP values.

KEY BENEFITS of installing arefrigerant leak detection system1. Safety – monitor refrigerant leakage to avoid harming people

and protect assets.2. E� ciency – leaks reduce energy e� ciency and may increase

wear and tear.3. Cost savings – reduce the amount of refrigerant being used.4. Environmental – reduce the amount of refrigerants released to

atmosphere5. Compliance – EN 378, EN 14624 and F-GAS.

“There are a number of di� erent technologies”

Useful tools are available, such as the

F-Gas Solutions app from Climalife,

which can advise GWP levels and calculate

the CO equivalent tonnage for all

common refrigerants.

SYSTEM FLUSHING24


As you will no doubt be aware, it is now illegal to use HCFC (Hydro chlorofl uorocarbons) refrigerants, such as R22, in any refrigeration, heat pump or air conditioning systems. This is due to its high ozone-depleting potential.

System Flushing Saves Time and Money Clean Through – Clean UpLIFE BEYOND R22

Therefore there were two options for such RAC systems:

By Tom Fitzsimons M.inst.R.DiversiTech Product Manager, Pump House

OPTION 1:Replace With New AC Equipment.Older systems, including those that are in poor condition, ineffi cient or not meeting their current (or forecast) cooling load, should be replaced with new systems using a non-ODS refrigerant. These can include HFCs (but these must comply with the EC F gas Regulations) or a “natural” refrigerant like hydrocarbons, ammonia or carbon dioxide. This option can have a number of benefi ts including a signifi cant improvement in energy effi ciency, a possible reduction in refrigerant charge, either by using new “critical charge” systems or by employing secondary coolants. However, replacement is the most expensive option in terms of up-front cost.

OPTION 2:Retrofi t to an Alternative Refrigerant For many types of RAC systems, as long as they are in good order, it is possible to consider a retrofi t solution. This could be as simple as fi nding suitable HFC refrigerant designed as a replacement for R22 and depending on the system type, could even be compatible with the system’s existing mineral oil. If not, then a system oil change will be needed to a POE oil and perhaps some additional modifi cations to add additional compressor and/or heat exchanger capacity.

If the decision is to retrofi t and it is necessary to change the oil

in the system, then a complete system fl ush is recommended to ensure that any remaining mineral oil and / or contaminants remaining in the system are removed prior to the introduction of the new oil and refrigerant.

There are a number of fl ushing systems on the market ranging from liquid based fl ushing fl uids which are “pumped” around the system for a period of time and then removed, to solvent based, high evaporation rate fl uids which are single pass products

One such system is DiversiTech’s Diversi-Flush system which is a safe, non-toxic, and residue free product. In addition, Diversi-Flush meets EPA’s Signifi cant New Alternatives Program (SNAP) standards.

ADDITIONAL BENEFITSOf course, fl ushing out systems and pipework in order to retrofi t an R22 system is only one use for a fl ushing system such as Diversi-Flush, as it can also be used to clean out and remove contaminants from systems following compressor burn outs.

It can also save a lot of time and money by being used to clean through existing pipework to reuse when replacing and upgrading indoor and outdoor AC units.

Diversi-Flush is distributed by Nottingham based Pump House and is available from most Refrigeration and Air Conditioning wholesalers throughout the UK.

Things to consider when choosing whichthe better option is:1) The age and condition of the current AC system 2) Existing and potential leakage problems 3) The e� ciency of the system 4) Cost 5) Whether alternative refrigerants are compatible 6) E� ciency and availability of an alternative refrigerant 7) The equipment manufacturers’ advice about using

alternative refrigerants

For many years R22 had been routinely used in AC systems but, since 2004, it has been

illegal for use in new AC equipment. It could, of course continue to be used in exiting systems for servicing and top up requirements, at least until 2010. However, in 2010 a European regulation called the ODS Regulation came into force which made using new, virgin R22 illegal to maintain existing RAC equipment.

Since 2010 only recycled R22 obtained from decommissioned RAC equipment or reclaimed R22 could be used for servicing and replacement and of course, such recycled or reclaimed R22 became increasingly scarce and expensive. As there were many systems out there that were still in service using R22 this has had an increasing eff ect on air-conditioning costs.

This all changed from January 2015 because it became illegal to use any R22, whether that be virgin, recycled or reclaimed, in any RAC system.

A2L – Mildly Flammable Refrigerants

Jane Gartshore, from Cool Concerns, explores the challenges with A2L refrigerants

WHAT DOES LOW FLAMMABILITY MEAN?Refrigerants are classifi ed according to their toxicity and fl ammability:

A: lower toxicity

B: higher toxicity

1: non fl ammable2L: lower fl ammability2: lower fl ammability3: higher fl ammability

• R404A and R744 are A1 refrigerants;• R717 is B2L;• Hydrocarbons such as R290 are A3 refrigerants;• The refrigerants listed in the table above (R32 etc.) are classifi ed A2L.

There is no perfect refrigerant. To meet ever strengthening F Gas legislation we need refrigerants with a low global

warming potential. But, these refrigerants all have challenges – the high pressure and system diff erences associated with R744 or fl ammability.

There are a number of new HFC type refrigerants which have low fl ammability. For this type of refrigerant there is a trade-off between GWP and fl ammability – the refrigerants with the lowest GWP are fl ammable. The low GWP / low fl ammability HFCs include:

The table to the right identifi es the characteristics which determine the fl ammability classifi cation.In layman’s terms this means that, compared to propane, you need more of an A2L refrigerant to achieve a fl ammable mix. It is harder to ignite and when it is burning the fl ame travels more slowly.

₀ When applying the refrigerant this means the maximum charge size is greater compared to HCs such as propane.

₀ When handling the refrigerants this means you should take the same precautions as you would with a hydrocarbon.

APPLYING A2L REFRIGERANTSEN378 is currently being revised and the revision will include A2L refrigerants. It provides data on lower fl ammability level and practical limits which then determine maximum charge sizes for diff erent applications. As an illustration, the table shows the maximum charge sizes for air an conditioned room, using R290 (propane, an A3 refrigerant) and R32 (an A2L refrigerant). The calculations have been done for a wall mounted indoor unit.

The calculations are valid for split systems or VRV / VRF systems for comfort cooling or heating. Cooling using chillers would generally enable a larger maximum charge size.

The diff erent A2L refrigerants would have slightly diff erent maximum charge sizes because they have diff erent lower fl ammability levels but the table shows that most splits, will be able to use R32 with minimal problems, whereas for HC, the charge limit is restrictive.

In addition, with A2L refrigerants, if larger charge sizes are required,

such as with VRV systems, it will be possible to use additional safety measures such as:

₀ Refrigerant detection plus alarm;₀ Forced ventilation which can

be permanent or turned on if refrigerant is detected;

₀ Automatic valve shut down to limit the quantity of leaked refrigerant into the cooled room.

HANDLING A2L REFRIGERANTSAs an industry we are already handling HC refrigerants – the handling of A2L refrigerant would follow the same procedure.In essence this includes:₀ Ensure the work area is well

ventilated a free of sources of ignition

₀ Ensure the correct tools and equipment are used (e.g. R32 recovery machines are now available)

₀ Prior to unbrazing, recover R32 from the system down to a vacuum and break the vacuum with dry nitrogen to avoid ignition

₀ Use appropriate leak detection.

Training for engineers on the safe use of A2L refrigerants is now available from suppliers and training providers (including Cool Concerns).

SUMMARYA2L refrigerants have a signifi cant part to play if we are to reduce the GWP of the refrigerants we use. The low fl ammability poses some challenges. Appropriate training is required and for many systems additional safety measures are needed. These will increase costs but are not major barriers or show stoppers for most end users.

R32 is a low GWP (Global Warming Potential) HFC

refrigerant which is back on the agenda and provoking some discussion in the ACR industry. There are air conditioning manufacturers that view R32 as the next cab off the rank to replace R410A – a high GWP gas which under the F-Gas Regulations will eventually be phased out.

Any gas with a GWP higher than 750 will be banned from use in low-charge split air conditioning systems from 2025. R32 is a single component, zero ODP gas with a GWP of 675, signifi cantly less than R410A which tops the 2000 mark.

Some leading manufacturers have more than dipped their toes in the water. In split air conditioners and heat pump systems they consider R32 as a good replacement for R410A and believe it will grow in popularity in the domestic and commercial markets.

A-Gas Managing Director, John Ormerod on why low GWP R32 is a good alternative to R410A in air conditioning and heat pump systems

EFFECTIVE ANDENVIRONMENTALLY FRIENDLYR32 is a tried and tested option for replacing R410A but like the hydrocarbons available it is mildly fl ammable. The long view on R32 has always been that it is an eff ective refrigerant with good environmental properties. This has been tempered by concerns about its mild fl ammability and to a large extent this has hindered its growth in the market.

A CREDIBLE R410A ALTERNATIVEIt has also been rejected in Europe in the past because of worries about its operating pressures but as the F-Gas Regulations have been ramped up, the popularity of R32 has grown and the gas is emerging as a credible option for R410A.

R32 is more effi cient than R410A and has an ASHRAE classifi cation of A2L or mildly fl ammable. Ironically, R410A is a mixture of R32 and R125 – the R125 suppressing R32’s

fl ammability. To my mind engineers and end users should not get stuck on the fl ammability issue. Now is the time to consider R32’s full potential.

THE FLAMMABILITY QUESTIONLegislation surrounding fl ammable gases is very black and white – they appear to be highly fl ammable or not fl ammable at all. No allowance is made for refrigerants like R32 that fall into the “grey area” of mild fl ammability.

R32 is particularly diffi cult to ignite. Flame speeds are very low and typically, if there is a problem, often or not the fl ame will die before causing any further issues. With this in mind, I believe that legislation on the amount of fl ammable refrigerant allowed in a public space needs to catch up with the needs of the industry. I am not alone in suggesting that changing safety and building codes is vital for the HFC phase-down.

R32 IN VRF SYSTEMSAccepting that R32 is a good alternative to R410A in air conditioning systems where charge sizes are pretty small, I expect more manufacturers to recommend the switch. Bear in mind that R410A is likely to get more expensive as the deadline looms, on that basis I predict that well before 2025 R410A equipment in smaller systems will be long gone and the industry will have migrated to R32.

I also suspect that R32 will be used in VRF systems before too long but as this happens air conditioning engineers will have to become more adept at risk assessing systems and their suitability for R32. Clearly, engineers will need more training in this area and to some extent a new PR off ensive is needed in persuading the industry that R32 is a safe alternative to R410A in larger size systems.

ATTITUDES TO R32 ELSEWHERER1234YF used in cars is mildly fl ammable but long ago vehicle manufacturers were persuaded that it was safe, as the associated risks could be managed, and to my thinking this also applies to R32.

The industry is also ready for the switch from an equipment perspective. Manifolds and hoses for R32 are already on the market – and there are recovery units and dedicated recovery cylinde vailable off the shelf that can deal with issues posed by R32.

Where R32 is already making its mark is in developing countries. Here refrigerant legislation is less advanced and this is where two thirds of R22 production ends up. R32 equipment is emerging as the popular candidate to replace R22 equipment in a straight swop. In Thailand R32 systems are widely advertised and in countries like this

change is likely to happen rapidly. It is fair to say that lower GWP

is very much a trade-off with mild fl ammability. Lowering GWP inevitably raises fl ammability and vice-versa but it should not be an issue that cannot be managed. If you are an engineer or an end user, start to understand that R32 is part of the future. The legislative pressure will not be too taxing on the industry but change will happen and I would advise that you should plan for it. So wise-up to fl ammable refrigerants, they are going to be around for some time.

HFC Regulation in the EU and US

explores hydrofluorocarbon regulation on each side of the ‘Pond’

,

Having successfully transitioned from the ozone-depleting chlorofl uorocarbon

(CFC) and hydrochlorofl uorocarbon (HCFC) refrigerants to the more environmentally acceptable hydrofl uorocarbons (HFCs), the traditional users of these refrigerants, blowing agents and propellants are again entering into a period of signifi cant change with respect to the portfolio of options likely to be available to them.

REFRIGERANT AVAILABILITY In an increasingly global marketplace it is important to understand at some level, the diff erences in the requisite regulations that apply to the products of interest. There is no doubt that such regulation will signifi cantly alter the refrigerant availability landscape with knock-on eff ects on import or export of refrigerant pre-charged products and on the selection of refrigerants for future equipment design and optimisation. Similarly end-users may need to manage their equipment estate with potentially multiple refrigerants serving the same purpose.

HYBRID APPROACHThe EU approach to regulation is a hybrid one where there is an overall cap on the quantity of HFCs that may be placed on the market coupled with specifi c bans on particular end uses. HFC consumption is then phased down by reducing the cap from its initial baseline value in stages through to 2030. This system is based on the CO2e so those refrigerants having the highest GWP will consume proportionately higher

proportions of the quota available e.g. 1 ton of R-134a consumes the same quota as 360kg of R-404A. Canada has recently proposed a similar hybrid approach.

HOW THE US DIFFERSThe United States EPA has adopted a diff erent approach, that of delisting. In the US, a refrigerant must be approved for a particular use prior to commercialisation and placed on an approval list, taking into consideration a number of factors including safety, effi ciency and the overall risks to human health and the environment.

This Signifi cant New Alternatives Policy (SNAP) program can limit approval for only certain uses or require certain precautionary measures to be in place. The delisting approach can lead to the situation where in some cases there is a blanket ban on the use of a particular refrigerant, either alone or as part of a blend, in others it leaves open the possibility of submitting new reduced-GWP blends for SNAP approval.

In contrast, the European regulation is focussed on specifi c GWP thresholds for acceptable

Whilst many HFCs have signifi cantly lower global warming potentials (GWP) than the fl uids they replaced (for example R-12 GWP = 10,900, R-134a GWP = 1,430), some HFCs are still perceived to have unacceptably high GWP.

MAC AND R-134AThis concern has led to the regulatory proposals and legislative measures in a number of regions including the MAC Directive (2006/40/EC) and F-Gas Regulation (517/2014) in the EU. The MAC Directive eff ectively bans the use of R-134a in new cars from January 2017 and the F-Gas Regulation imposes a phase-down in the total CO-equivalent (CO2e)

sales of fl uorinated gases into the EU market coupled with a number

of specifi c end-use bans.

and environmental aspects and the availability of suitable alternatives perhaps allowing a degree of fi ne-tuning as to what GWP is most appropriate for a given end-use.

There is growing movement towards a more global approach to HFC regulation. The Kyoto Protocol, which particularly focuses on CO but also encompasses some fl uorinated gasses, has perhaps been less eff ective than originally anticipated. There have been moves over the last few years to amend the Montreal Protocol to include HFC phase-down with proposals from at least the EU and collectively from the United States, Canada and Mexico (NA).

An indication of the rate of phase-down in CO -equivalents for the NA proposal is shown in Figure 1 with the existing EU F-gas phase-down schedule for comparison.

from mid-2016 is likely to promote the use of the remaining approved fl uids such as R-407A. Unlike F-Gas where the use of virgin HFCs with GWP greater than 2500 for servicing is banned from January 2020, there are no apparent restrictions on servicing existing equipment with their original HFC in the Final Rule.

Unlike F-Gas, there is no specifi c CO2e ceiling imposed in the SNAP Rule. Instead, we would expect that the specifi c end-use controls imposed will result in a signifi cant reduction in CO2e emissions based simply on the eff ective bans on, for example, use of R-404A/R-507.

Whilst the European approach has hard-coded GWP maxima for any alternatives to be used in various applications, the US will use the SNAP approval process to determine refrigerant acceptability taking into consideration safety

SUSTAINABILITY AND GROWTH PLANNING FOR TOMORROW A commodity that most take for granted. Seen by a many as worth more than gold, and with most people unaware that this treasure can be right in the room with them... Serge Becker of Aspen Pumps explains more.

35CONDENSATE REMOVAL


SUSTAINABILITY AND GROWTH – THE CITIES OF TOMORROWAs more countries around the world look into smarter ways of urban development and sustainability, we are seeing a signifi cant growth in resource being channelled towards more self-sustaining and ecological construction solutions.

At the last count, Asia had a population of 427 billion people, which accounts for over 60% of the world’s population. Although there are still vast amounts of people living and working in rural areas, Asia is now over 40% urban. Providing water, sanitation and other resources is easier for the Government to manage when people live in close proximity to each other and opportunities for sustainable development and energy management are easier to predict and manage.

During the late 1980’s and early 1990’s, the whole concept of eco-cities were generally thought to have been the dream of idealistic people and generally out of reach. However in recent years not only has the dream become the reality, we are seeing more and more countries take up the sustainability baton and try to replicate others success. The ideology behind the construction of these cities follows very simple rules. They must be in line with the cities natural growth, they should encourage more environmentally and socially responsible behaviour and should have a minimal ecological impact when being developed.

Many of these developments follow strict environmentally friendly

guidelines when being constructed to ensure minimal impact on the environment during build up. To develop a fully functioning Eco City, developers and architects will look at waste management, energy saving initiatives, urban layout, poverty reduction and water recycling. These considerations help to maintain the green infrastructure being created.

Interestingly of all the sustainable practises that the eco city developers take advantage of, water recycling is one of the most overlooked. Although there are sustainable urban drainage systems, rain water harvesting and Xeriscaping (advanced irrigation systems,) a huge source of water recycling potential is overlooked.

“Condensate water generated by air conditioning units is an often overlooked resource when developing sustainable cities. With the right drainage systems and correct pumping methods, it is entirely possible to have suffi cient recycled grey water to signifi cantly impact on water recycling.” Serge Becker explained.

Sustainable cities are not a new phenomenon in South East Asia. India for example, will be investing more than $10 billion on clean energy in 2015, (according to a recent forecast from Bloomberg New Energy Finance (BNEF),) and Singapore will be supporting the Indian State Andhra Pradesh in building a new sustainable capital city at a cost of $16.5bn.

Serge Becker went on to say: “Aspen Pumps is a company who has been at the forefront of air conditioning grey water recycling innovation and it has been providing water condensate removal solutions to the industry for over 20 years. Being able to reuse grey water is imperative to ensuring that Aspen, and other companies involved in this area, work in a way that can only benefi t sustainability projects. Aspen off ers a range of pumps that will lift the water up and into storage tanks, outside water butts, and other water drainage systems, which means that the water can then be reused and recycled as appropriate.”

Incredibly an average tower block with 150 fl ats - could recycle up to 22,500 gallons of water per month, which is enough water to fi ll a 21ft swimming pool! With over 50 million air conditioning units used in China annually, if every one of those units had a condensate water pump fi tted, there could be a saving of over 700 trillion gallons of grey water per year.

With more than $1.6 trillion invested in 2013 in energy supply, the focus on energy savings is growing. Eco cities that can house millions of people are on the rise and water – which can be a scarce commodity – will in turn become more valuable. With this in mind, forward thinking governments, architects and engineers will be looking at the recycling opportunities that condensate water presents. This easily accessible source of grey water can be accessed with the right pump, trunking and accessories and the average household will reap huge benefi ts from water sustainability and economic savings. This means that whatever the country or environment, if there is an air conditioning unit, there is an opportunity to tap a valuable source of recyclable grey water.

Condair CP3electrode humidifi er

Dave Marshall-George, UK Sales Manager, Condair plc

Condair RS resistive steam humidifi er

Electrode and resistive are the two main types

of electric steam humidifi er a HVAC contractor will buy and install. Both are versatile and come in a variety of sizes for either in-room or in-duct applications.

From a contractor’s perspective the main considerations when selecting a unit are often purchase cost and ease of installation. For a customer or end-user the initial cost is also important but so are on-going operating costs and maintenance requirements.

STEAM CREATIONThe main diff erences between electrode and resistive technologies are how they heat the water to create steam and how they control steam output.

The electrode boils water by passing electrical current through it. The more current passes through the water, the greater the steam production. So output increases with a higher water level or when higher mineral levels make the water more conductive. To maintain an accurate output, the concentration of minerals in the water is regulated through drainage and replacement with fresh water. This typically allows

for humidity control of around +/-5%RH.

Resistive humidifi ers create steam through the transfer of heat from the resistance heater elements to the water. Steam output is controlled by applying more or less heat to the water rather than controlling water level or conductivity. This results in more accurate humidity control of around +/-2%RH with mains water.

As the mineral content of the water has no impact on steam output, resistive humidifi ers can also operate on RO water. As the mineral content of the water is very low, this virtually eliminates scale build-up, signifi cantly reducing maintenance requirements. It also improves humidity control by removing the need for fresh (cold) water to be regularly introduced to reduce mineral levels. A consistent water temperature results in a consistent steam output and enables a resistive humidifi er operating on RO water to control humidity to +/-1%RH.

DE/HUMIDFIERS36

Dave Marshall-George, UK Sales Manager at Condair plc (formerly JS Humidifi ers), looks at the pros and cons of electrode vs resistive electric steam humidifi ers for the contractor and their customer.

Electrode vs. Resistive Humidifi ers


Condair.indd 36 14/08/2015 14:02:51

37DE/HUMIDFIERS

COSTSElectrode humidifiers tend to have the lowest capital cost of the two technologies. Installation costs for both electrode and resistive are comparable plus both are simple to install as they require connection to power, water mains supply and drain only.

The cost of operating a steam humidifier is largely determined by two things. The energy required to turn water from a liquid to a gas and the cost of dealing with what’s left behind in the humidifier after this has happened.

When run on mains water, the energy costs are the same for both humidifiers, as they use the same amount of electricity to create the steam. However, if the resistive unit is run on RO water, electrical consumption is less as very little hot water is sent to drain. Although energy consumption is improved by the use of RO water, water consumption is increased as 50% of the water is sent to drain as part of the initial filtration process.

With an electrode boiler, as steam is produced, any minerals in the water build-up within the plastic cylinder as limescale. When these cylinders are full of limescale they are replaced, which is straightforward

and offers the benefit of very rapid maintenance and minimal downtime for the humidification system. The disadvantage is that cylinders can be expensive and represent an on-going spares cost.

As resistive steam humidifiers do not pass current through the water they can operate with stainless steel boiling chambers that can be cleaned rather than replaced. This avoids the expense of disposable cylinders reducing spares costs. So much so, that the initial cost of the more expensive resistive unit can be recouped within 18 months.

So although on-going operating costs can be less with a resistive humidifier, servicing takes longer as the unit needs to be emptied of scale. However, some advanced systems, such as the Condair RS resistive steam humidifier, reduce this service burden through innovative scale management features. An external scale collector allows limescale to be removed quickly and easily without needing to open the main body of the humidifier, greatly reducing service time.

SUMMARYAs we’ve seen, both technologies have advantages and disadvantages and the choice of

system largely depends on the end-user’s needs. If very close humidity control is needed resistive humidifiers with or without RO water could be the best option. If close humidity control isn’t important, but simple maintenance with minimal downtime is, an electrode boiler with its replaceable cylinders could suit. But if a customer wants the lowest whole life cost across capital, service and consumables, then a resistive humidifier will provide this.

The most important thing to remember when advising your customers is to get good guidance from a competent supplier. From product selection to servicing, there are often opportunities to up-sell to improve your customers’ satisfaction and avoid many common errors along the way. A quality humidifier supplier will work alongside you to help you make the most from each project.

Things to specifically look for in a supplier include a comprehensive range of CE approved products, a company, which offers support and advice on installation, commissioning and servicing, and quality standards such as ISO and Investors in People.

When ice isn’t niceAnyone involved in operating a cold store

will be familiar with the problems that can result from iced up evaporator coils as a result of excessive humidity in the air. Not only does this impair efficient performance, it also potentially leads to downtime for defrosting.

High humidity in cold rooms can result in reduced energy efficiency and disruption to processes. John Barker, Sales Director of Humidity Solutions discusses desiccant dehumidification and the potential for heat recovery.

Dehumidification has been the accepted solution for many years, with desiccant dehumidifiers being the technology of choice in most applications. Desiccant dehumidifiers can reduce moisture levels at temperatures as low as -70°C, removing moist air from the cold room and re-introducing dried air.

However, the operation of a desiccant dehumidifier results in the dried air that re-enters the cold room being at a slightly higher

temperature than the air in the cold store. This is because as the water vapour in the air is adsorbed onto the desiccant, some heat energy transfers to the air.

Clearly this is a concern for some cold store operators as there is an inevitable – albeit small – increase in energy consumption to cool the air again.

RECOVERING HEAT (COLD)One solution to this problem is to use heat recovery – though in this case perhaps it should be called ‘cold’ recovery as it works in reverse to the heat recovery process used to conserve heat in buildings.

This works by passing the dried air through a plate heat exchanger

John Barker,Sales Director,Humidity Solutions

Dehum schmatic

Desiccant dehumidifier

How desiccant dehumidification works

Rotary desiccant dehumidifiers work by using a desiccant substance such as silica gel to adsorb moisture from the air.

Air is drawn from the cold room through a filter and passes through a desiccant rotor (a rotating wheel containing desiccant) where it gives up most of its water vapour, so that as the air passes out of the other side of the rotor it is drier than when it entered the rotor. The moistened section of the rotating desiccant wheel then passes through another air stream that dries (reactivates) the silica gel and this moistened air is exhausted to the atmosphere.

For cold rooms, experience shows that the choice of desiccant is important, as it mustn’t deteriorate under low humidity conditions. Synthesised silica gel has shown itself to be both chemically and thermally stable with low maintenance requirements as it can be washed with water.

where the sensible heat that was gained in the desiccant rotor is given up before the air returns to the cold room. The key thing here is that there is no change in enthalpy (isenthalpic) so the dried air returns to the cold room at the same temperature as it left, thus there is no increase in refrigeration requirement.

The key point here, when selecting the best option for a particular cold store, is to get the right balance of capital investment against reducing operating costs. A desiccant dehumidifier, without the heat exchanger, will still deliver significant energy savings by preventing the icing of the coils. This more than compensates for the slight increase in temperature of the air returning to the cold room.

Introduction of heat recovery will certainly increase these energy savings, but additional capital investment in a plate heat exchanger will be required – so the critical question is what sort of payback will that extra investment deliver?

The answer to that is, that it will depend on the individual application. There is no hard and fast rule that will cover all eventualities. So, it is advisable to seek specialist advice to ensure getting the best solution that delivers the required performance with a sensible return on investment.

Modern-day air conditioning

Pacair UK revisits 30 years of controls

In 1985, a new range of ducted split systems were launched in the UK. All very basic and of course they used R22. A choice of

two fan speeds was made during installation and the compressor operated at a fi xed speed. But they included a previously unknown feature: A single controller which could be networked to up to 16 indoor units that independently heated or cooled around a common set point; and to reduce the eff ect of simultaneous inrush currents, compressors were started separately.

41CONTROLS



In the subsequent thirty years, control of air conditioning systems has continued to develop.

Whether using split or VRF systems, end-users have become accustomed to sophisticated control systems. The local controllers, which still follow Toshiba’s original 120 x 120 mm dimensions: incorporate temperature sensors, can be scheduled for weekly operation, can provide run/standby operation in equipment rooms, and even incorporate PIR movement sensors to stop the air conditioning unit when the associated room is unoccupied. A wide range of features can be confi gured from the controller, allowing the air conditioning equipment to be fi ne-tuned to the application.

In machine-room application the standard controller can be used to provide run-standby operation of two systems with the standby unit

automatically started if a fault is detected with the running system and/or the room temperature is too warm.

SMS technology has been used to monitor un-manned rooms via a mobile telephone. An alert being broadcast if the air conditioning equipment has a fault or the room is too hot or cold. In turn, new settings can be sent from the telephone as a text message.

CENTRAL CONTROLWith increasing network speeds becoming available, central control has allowed over 200 indoor units to be controlled from a single point. The life of the Facilities Manager has been made considerably easier with this development. Room temperatures and the status of the indoor units can be monitored and any changes made to the settings locally will be refl ected centrally (and vice versa. This became even

easier when central controllers were able to be connected to the local area network and all functions are accessible through standard web browsers.

Additional functions, now available through central controllers, include: automatic correction for British Summer Time and Greenwich Mean Time; a timed set back function, which instructs the local air conditioning unit to operate in the most effi cient manner, should a local area become too hot or too cold; connected equipment can also be interlocked through the central controller (a room is ventilated when the air conditioning is used; an indoor unit is operated when another is in an alarm condition); outdoor units can be instructed to operate in a quiet mode, overnight.

Confi gurations can be saved on a USB memory stick, allowing settings to be backed-up; these

Continued from page 41 settings can easily be copied to other controllers that will be used in a similar application.

A common application is hotel rooms: to standardise the room conditions, they are reset to standard, seasonal settings, when the air conditioning is fi rst started, while allowing; they are automatically stopped on the guests’ departure to minimise unnecessary power consumption; and for the conditions to be prepared during the popular check-in times (this feature is disabled overnight, to prevent the air conditioning from starting unexpectedly).

Central control can also operate with 3rd party equipment: • Temperature and humidity

sensors can be monitored with a programmed response to out of range values;

• Pulse meters can provide data from gas, water and electricity meters (billing software can use the electricity consumption and link it to demands from the associated indoor units, to produce apportioned bills).

• Digital inputs and outputs can be controlled and monitored. They can be given their own operating schedule and/or interlocked to the associated air conditioning equipment. An input from an underfl oor heating system can be used to disable the air conditioning.

CONTROL VIA COMPUTERThe central controllers can be given suitable IP credentials and connected to the Local Area Network; indoor unit performance can then be monitored and adjusted via a standard web browser. This method is very powerful and easy to set up and can provide a central control point for an entire building.

When required, all common BMS protocols (Trend, Lonworks, BACnet, Modbus, KNX) are supported via an appropriate interface. While the primary functions (on/off control; mode selection; set temperature; fan speed and louver position) can be monitored and controlled through the BMS, we recommend that the air conditioning equipment’s intrinsic controls are used as far as possible; while any values (including error codes and air temperatures) can be monitored.

CONTROL PANELSIn order to simplify the installation of these controls, PACAIR design and supply bespoke panels, which are fully manufactured, set up and tested prior to despatch. The amount of setting up is of course dependent on the appropriate information being supplied. The objectives are to provide a combination of controls, power supplies safety devices and connections that are manufactured and tested in a workshop environment. They normally, just require a power supply and the external components to be connected. Network connections are provided on the side of the panel, and socket outlets are provided to assist the commissioning and service engineers.

WHAT NEXT?In the 30 years of networked control we’ve seen plenty of developments. Liquid Crystal Displays provided an opportunity for much more information to be made available to the customer and service engineer. But this information was accessed by a bewildering sequence of the 20 buttons on the key-pad. Local controllers have now become much easier to use, with typically 8 intuitive buttons, which are intuitively used to navigate through the various functions which are password protected at multiple levels.

WiFi technology has been introduced. However, the security of a permanently wired, central controller is a sensible addition.

Virtual local controllers can be set up on end-users’ computers, allowing them to control their own environment without the need for a physical controller.

Central controllers now use touch screens as standard and have become much easier to use and set up. Compatibility with all external controls will continue to be important; control over energy consumption is featured in all developments.

But what other developments can we expect over the next thirty years? 1

CAREL’S UPGRADABLE MODULAR PLATFORM HERALDS NEW GENERATION OF CONTROLS

The ‘UltraCella’ which is the largest of 3 controllers in the range, is aimed at medium, large and specialist coldrooms, and represents an impressive

evolution based on the experience and success of their existing and well established mid-sized ‘MasterCella’ controller. CAREL has also launched the ‘SmartCella’ for small coldrooms earlier this year, and thereby ensuring the range off ers a solution for coldrooms of all sizes.

with or immediately allowing you to synchronise defrosting of multiple units.

Evaporator fans management – evaporator fans can be forced to work even when the compressor isn’t working, to avoid stratifi cation inside the cold room (food being at diff erent temperatures depending on whether it is on a high or low shelf).

Data Logging – pull down the temperature information you need onto a USB stick for ease of collection and storage.

Other key features include – Floating Condensing pressure for energy saving, variable speed condensing fan control by pressure / temperature, Humidity logging, high & low humidity alarms, Set point variation by digital input, smart management of the light activation and many more.

COMPLIANT WITH HACCP UltraCella is fully compliant with HACCP international food safety standards. It can store and visualise up to three high temperature alarms and show the day, hour, minute and temperature on a scrolling text display.

USB AS STANDARDUltraCella has 4MB of internal memory available for data logging so it can store temperature data for up to 4 years. This can be saved as a CSV fi le and exported via USB so that is instantly available in Microsoft Excel for use by an end user or a standards inspector.

CAREL’S new ‘UltraCella’ Coldroom Controller is the latest addition to the company’s ‘Cella’ range of coldroom solutions and is already increasing the Italian manufacturer’s market share and UK customer base.

‘UltraCella’ really off ers total control: It is easy to install with an installation track for DIN rail and more GND terminals. Commissioning is simple with several ways to set up the coldroom: using the Wizard, which guides you through set up by asking you a series of simple questions; selecting one of 10 preset confi gurations for main conservation room types or uploading the profi le from a USB stick.

As you would expect from any of the CAREL range, the interface design is excellent and day-to-day operation is highly intuitive. The big display ensures clear messages and a double display option allows you to show two functions at the same time, for example temperature and humidity.

ULTRACELLA PROVIDES TOTAL CONTROLCompressor management - with safe coldroom working mode in case of virtual probe failure – so food doesn’t deteriorate while waiting for service.

Defrost management – defrost can be activated by a button on the keypad and by digital input

“Unique in the controls

market”

The ability to upload and download via USB also means when you have multiple coldrooms to set up you can commission one, then download the settings and upload them to all the subsequent units saving valuable time. Similarly when new contents, algorithms and applications are released it will be simple to upload software directly.

INNOVATIVE UPGRADABLE MODULAR PLATFORMThe feature that makes ‘UltraCella’ unique on the controls market is its innovative modular design, which, as an open platform, allows you to add features as required and upgrade quickly and easily as new modules are released.

There are currently four easy to assemble expansion modules:

WOMEN IN ACR46


This month’s ‘Women in ACR’ interviewee is Lisa Woodcock from Oceanair.

Details of current employerI work for Oceanair UK Ltd in Mansfi eld. We are distributors of Panasonic air conditioning units and heating products. They are a great bunch of people and I worked with most of them in my previous employment.

What type of projectsdo you work on?All sorts really, from a single split system to Air to water heat pumps, VRF and Gas engine heat pumps. I really enjoy working with contractors and consultants, getting work specifi ed to Design and Build (D & B) projects which are challenging but very rewarding.

What is the most memorable project you have worked on so far?In 2013, we worked with restaurant chain Carluccio’s to reduce their energy bills as well as their carbon footprint.

FWP Air Conditioning had been asked to install a system which would provide the desired volume of hot water, at the correct temperature while at the same time reducing energy costs. This is where we at Oceanair stepped in to specify Panasonic’s Aquarea air to water heat pump system as the perfect sustainable solution.

Following a consultation with Carluccio’s, it was decided that the restaurant chains new site in the Meadowhall shopping centre in Sheffi eld would be the ideal location as it had the correct attributes for

the installation of an air to water heat pump system. Previous restaurants in the chain had been fi tted with a more traditional 12kW boiler system.

FWP installed Panasonic’s 12kW Aquarea T-CAP mono bloc unit which would allow for the free air from the kitchen roof space to be transferred through condensing unit providing hot water at the optimum temperature. With a high coeffi cient of performance (COP), for every kW of electricity the system uses, it provides 4kW of energy. This makes the Aquarea far more cost eff ective than a conventional heating system.

Later in the year when Carluccio’s compared the Sheffi eld site to one of their existing restaurants of a similar size, the energy savings were considerable. To heat the water for their Leeds restaurant cost £3782 whilst at the Meadowhall site the comparable cost was just £951. These sizable savings meant the site saw a return on investment within two years and has achieved a COP of 3.91.

Describe your typical day / the sort of work you’re involved in? It can vary dramatically, from site visits, delivering the odd split, to talking through VRF designs.

What attracted youto the industry?I started off working behind a trade counter, meeting and chatting to the engineers and getting to know the industry; which I really enjoyed. So it’s the people side, I suppose.

Name and job title including brief summary of roleLisa Woodcock, Area sales Manager at Oceanair UK Ltd. I work with contractors and consultants helping them with designs and provide them with equipment that is best suited for their applications.

Where did you study and what course? I had a traditional education not really building services biased, although my Father and uncle were both Refrigeration engineers, so I suppose it’s in the blood! I still have my dad’s college text books from 1962.

WOMEN IN ACR

What excites you about the industry and your part in it now?There’s a lot going on right now, air to water heat pump development, R22 replacement and the continued growth of VRF. It feels like the industry is getting back on its feet and we are working with some great clients who are doing really well.

What would you say to other women who are considering coming into the domestic or commercial heating and cooling industry?It’s a people industry and as long as you do what you say you are going to do and look after your customers, it’s a rewarding one. I know my technical abilities and limitations. But I have a great team around me who I can trust and always have my back so don’t be put off by the technicalities, just make sure your team support you!

Have you ever felt that being a woman has prevented you from developing your career in this industry, or compromised your prospects in any way?No, never.

Where do you see your career developing?I love my job and the people I work with. We have completed some serious projects in the past but I am equally happy delivering a unit for a customer, who needs it desperately, so more of the same, please!

What are the challenges in this industry?Margins are still tight and recently we have seen a number of casualties who couldn’t sustain their businesses because of that. We still have the challenge to keep prices low but to also make sure that the equipment is right for the job.

What are the benefi ts of being in your role?I have the freedom to go where I’m needed. I have a very varied day, I see diff erent people, a lot of which are now friends. I particularly enjoy seeing my work come from design through to commissioning. I work with a very knowledgeable team who never let me down and allow me to make promises I can deliver to people who trust me so it’s great!

OUT AND ABOUT48 OUT AND ABOUT


Out and About with Will HawkinsWeatherite

Will Hawkins visits bespoke air conditioning and air handling systems manufacturer Weatherite,to see what makes this company so successful.

It must be good being a Weatherite customer. The

‘Black Country Welcome’ is probably one of the warmest in the industry. And that comes right from the top of the business from Weatherite’s chairman, John Whitehouse.

John explained how he started the business in 1972 from ‘humble beginnings’ and how it evolved into the group today. It is designing, manufacturing, installing and maintaining heating, ventilation and air conditioning (HVAC) systems for retail and industrial customers. Weatherite has no products on its shelves. Everything it produces is bespoke.

He put its success down to investing wisely in both people and

machinery. But mainly due to the people and providing them with the right working environment. Some of his team have been with him since the early days. For example, Technical Director, Paul Griffi ths, joined the company two years after it started.

OPEN COMMUNICATIONSAlthough the company has ‘line management’ in place, the business does not rely on it to hear what is happening. John gets out among its people and speaks openly with them. He is an approachable man and you can see this works well. In other businesses, employees often complain that the lack of internal communications means that the company works in ‘silos’ and not together. That looks unlikely to happen at Weatherite when the senior leadership is so close to its employees.

Communications are important in the business. But, to evolve, you also need to invest to be successful. John explained that making bespoke solutions requires a lot of brain power. They do not rely solely on computers to design their solutions. The deep experience of the team is crucial to their success. They have a joint venture in research and development with a local university.

The venture and the approach encourages people to think and get away from ‘the norm’.

SELF-RELIANCE AND INVESTMENTJohn does not have much patience with politicians or bankers. When talking with a former Trade and Industry Secretary about unnecessary EU regulation and its list of ‘3,000’ rules imposed upon businesses, the politician did not believe him. John described this ‘out of touch’ politician in a short but meaningful way.

By investing back into the business, Weatherite has not had to rely heavily on bankers to innovate and evolve. John would, no doubt, have had some equally succinct and descriptive phrases if he had had to lean on fi ckle banks for investment.

RIGHT FOR THE UKMany Weatherite customers are consultants and, John explained, they prefer not to design or build ‘from a catalogue’. This approach is diff erent from the US. In the 1960s and 70s, air conditioning was dominated by American products. But, their approach was not totally right for the UK market.

As a result, the UK’s production approach evolved into a market which has a number of smaller manufacturers using low cost

machinery to make products suitable for UK conditions. Now, Weatherite ships its products across the globe. On the factory fl oor, on the day I visited, a system ready to be shipped to Qatar.

John and his team saw this need and set up the business to help UK customers with UK solutions. Weatherite creates a wide range of solutions for customers who need anything from data centre cooling, to heating solutions, to air conditioning in large buildings. The company has a long relationship with many of its customers. For example, Marks and Spencer has been a customer for 30 year’s. Tesco is another long-standing client.

Despite the long relationships with customers, John is not complacent.

“We place them on a pedestal,” he said. “Customers need a secure route to solve their problems. We are very good at these.”

To illustrate the point, John explained how a senior engineer in a retail client had, in 1989, challenged them with an HVAC problem concerning their existing in store bakery extract product. The Weatherite team provided him with a design within two weeks and solved the problem quickly afterwards. The retailer has a been a customer ever since.

The teamwork, great communications and experience built the company’s reputation in

the industry for meeting and beating customers’ expectations. Customers have exacting demands on cost, space and effi ciency. Weatherite is very good at providing what their customers want and need.

BIGGEST YEAR FOR NEW PROJECTSThe retail market has taken a beating recently with increased competition and price wars. To counter any reliance on one market, John and his team are constantly looking at new markets for their skills. It seems to be going well. This year (2015) has been their biggest ever for new projects.

A major cinema chain is a new customer. John cited a project where they replaced an air conditioning system on the roof of a site which had to fi t into the existing space used by the old system. Shutting down the theatres entirely was out of the question. Weatherite managed to design, build and install a new, far more effi cient system in the same space. The customer lost no revenues and is now saving enough on its energy bill to help provide a quick pay back.

CAN DOIt is Weatherite’s ‘can-do’ attitude which is perhaps its most impressive attribute. John leads this and summed it up as follows:

“We have never had any major problems in our business. It is because we never walk away from problems. If something goes wrong, we always fi x it.”

That is why it must be good to be a Weatherite customer. Their customers must feel as though they are being looked after by some of the most intelligent, caring, friendly and determined people in the industry. In a world where there is a lot of talk about ‘customer service’ and ‘innovation’, Weatherite is one company that delivers on both, brilliantly.

MAINTENANCE52


The development of acid in air conditioners and refrigeration systems causes serious internal corrosion, reductions in performance and can drastically

shorten the lifespan of both your compressor and your refrigerant.

These acids can be formed by the presence of air and water in the system and by chemical reactions with components and/or materials of construction, lubricating oils and/or impurities.

If a system is not operating at optimum effi ciency due to clogged air fl ows or a failed condenser fan, the increased temperatures will accelerate the formation of acids. The more acid you have, the more will form, creating a destructive build-up of acid.

If this chain reaction is left unchecked, you can face serious problems. The acid will corrode the system from the inside, attack the compressor and increase the wear on motors and components and likely lead to an expensive and fatal compressor burnout.

Regularly checking a system for acid is therefore an essential part of every professional engineer’s preventative maintenance routine.

TESTING FOR ACIDIf you suspect that an HVAC system has an acid problem, you will need to test the oil for acidity. The method you choose is likely to be an oil sample from the system.

For systems which don’t give engineer’s easy access to the oil, a product such as QwikCheck is ideal.

In the fi rst of a series of “How To…” articles by ACR service and maintenance experts, Advanced Engineering, we discuss the common problem of corrosive acid in refrigeration systems, how to detect its presence, and how to e� ectively remove it from a system.

detect and remove acid from HVAC systems

It works for all refrigerants and oils and is safe for all systems.

The engineer can take a small sample – via the low pressure service port – by venting a short blast (2-3 seconds) through the QwikCheck. If acid is present a colour change will occur?

Where engineers can access the oil, a more traditional test solution such as RectorSeal’s Acid Detector for POE can be used. Add a small amount of the sample oil into the supplied glass bottle and the colour change liquid will show how acidic the oil is.

SOLUTIONSQwikShot Acid FlushQwikShot Acid Flush works by chemically attaching to the acid and/or moisture molecules and fl ushing them to the fi lter drier.

It’s added to the compressor oil using the companion QwikInjector applicator. It works with all refrigerants, oils and fi lter-dryers; does not leave behind any disruptive residues; and it is a proven method for removing acid rather than neutralising it.

The only disadvantages are that it is not an “on-guard” product, so it will not alert you to the formation of acids, and once it has captured the acid it must be removed from the system (along with the acid) using a fi lter dryer, which can be time consuming.

CONCLUSIONWhichever method you choose, it is the duty of every good service engineer to be both aware of acid levels in HVAC systems and be ready to deal with them before they cause irreversible system damage.

If you need further information about anything in this artice contact the Advanced Engineering support hotline on: +44 (0) 1256 460 300.

Spectroline Acid-BusterSpectroline’s Acid-Buster is arguably one of the quickest and easiest solutions to the problem of acid.

It is a ready-to-use acid scavenging solution that is simply injected directly into the low pressure service port using the proven EZ/BEZ injector, a handy, pre-fi lled, calibrated, disposable cartridge. This delivers the precise amount of acid neutralising treatment necessary – avoiding the risk of any overdose.

RectorSeal Acid-Away POERectorSeal’s Acid-Away POE (polyol ester oils) is one of the most well-known and popular acid solutions on the market.

It operates on polyol ester lubricants and requires direct access to the oil. The uniquely eff ective formula circulates throughout the system and chemically neutralises any residual acids and prevents them from corroding the system.

It will work with all refrigerants and oils and all HVAC systems and, like Acid-Buster, it remains in the system and continues to neutralise acid as it forms, until all treatment is exhausted, making it an eff ective preventative maintenance method.

September 2015 heatpumps.today

Straff an Manor has recently been announced as an award winning development in the

Panasonic PRO Awards 2015. A Panasonic Aquarea heating and hot water system was installed in all 21 of the 5-6 bedroom luxury homes in Straff an Co.Kildare, Ireland.

Aquarea Heat Pump success in Ireland’s famous Ryder Cup village

THE BRIEFThe client, Mulberry Properties Ltd was dedicated to not only comply with building regulations but aspired to surpass them to set a new standard. The key objectives in the construction of these new homes were to ensure that they achieved an A2 building energy rating utilising renewable energy sources and exceed the requirements to reduce the carbon emissions outlined in Part L. Mulberry Properties Ltd wanted to install a user friendly heating system that would be easy to operate and maintain now and in the future, as well as complement

the overall aesthetics of the development. Other key features taken into consideration were energy effi ciency, low running costs

and minimal disruption or excessive ground works during the construction phase.

THE PANASONIC SOLUTIONAfter extensive consideration between Shane Duff y of Heat Merchants, Mick O’ Shea and Mulberry Properties Ltd, it was decided that a system featuring a heat pump was the best. This off ered the capability to integrate the heat pump with other additional renewable energy solutions, thus delivering high performance whilst remaining energy effi cient and aff ording the added bonus of low running costs. The excellent build quality of the Aquarea

units coupled with the availability of a local Panasonic service engineer sealed the deal.

The new homes now benefi t from a split system, which generates 100% of the domestic hot water and heating needed for the homes all year round, without the need for back up from a supplementary system. The requirement of heating stored hot water to eliminate the risk of Legionella.

Unlike conventional systems, there is no need to prioritise between heating and hot water. Due to the large volume of the thermal store there is never a dramatic drop in the temperature, allowing the Aquarea heat pump to comfortably recover the temperature. This solution maintains the effi ciency of the heat pump keeping both energy consumption and costs to a minimum.

An opinion for discussion?By Rich Cartwright BEng MCIPHE, Director of RDC Energy Ltd

Heat pump manufacturers are researching and developing their models to be more

efficient by improving components, refrigerant and using inverter driven compressors. Weather compensation has also proved to be an excellent way to control your heat pump and improve running costs and performance.

pump installers will recommend, the heat pump should remain on at a low steady operation, trickling out a 35 to 45°C flow temperature into the distribution system radiators, underfloor, fan convectors etc.

Using weather forecasting live data which communicates to the heat pump program via internet connection could well provide a new intelligent method of operation.

Since air source heat pump performances are improved with warmer external air conditions, and winter day time temperatures are warmer than twilight hours, it would make sense (not in all cases) to turn the heat pump on in the day time and store the heated water in a thermal store. This saves the energy within the thermal store for twilight demand. There will, of course be days when heating is required in the day time and therefore the weather forecasting heating operation could not be activated. But during day times (6am to 8pm) when heating demand is low and the weather is predicating low temperatures at

twilight hours this new approach of operation could work well.

The size of the thermal store will be calculated from the daily energy demand for the property, hence a room by room heat loss calculation is required.What size thermal store would be required?A typically well insulated new build 2 to 3 bedroom property would potential only need between 5000 to 9000kWh of energy per annual for heating. Therefore if we assume on a cold winters day 10kWh of energy is required to heat the home (24 hours period) and the maximum flow temperature to the underfloor heating is 45°C. The delta T is (45°C – 20°C) = 25°C

We can assume if the thermal store energy is completely used each time there is a demand, then towards the end of the usage on the return pipe temperatures could be 20°C (feeding into the bottom of the thermal store). The thermal store would then be ready for another forecasted heating period.

We can calculate the estimated size of the buffer:

A new intelligent method of operation for air source heat pumps

Litres of water for thermal store =

Litres of water for thermal store =

Energy (kWh)

(ΔT) x specific heat capacity of water J to kWh( (

10

(25K) x 4187 3600000( (

Therefore litres of water required for thermal store to be heated on a daily basis (winter days) = 344 litres

A 3.5kW air source heat pump would be able to heat up the 344 litre store within 3 hours.

A good location for this thermal store in a 2 to 3 bedroom house could be challenging, but the architect could design a suitable location for it, possibly bury it in the garden using an anti-corrosion cylinder. This of course can lead on to more ideas to discuss.Would be great to hear from manufacturers, maybe we could start working together on this. Email:[email protected]

Rich Cartwright

As I’m not employed by a manufacturer and therefore am not involved with internal product improvement, I started to think about other parameters which could influence an air source heat pump’s efficiency.

The EN 14511 standard of presenting air source heat pump’s performance is based on 45°C flow temperature and 7°C outside. Heat pump manufacturers like publishing this, because the unit output and COP are then extremely impressive. However, professionals who are familiar with the technology know how important it is to review the performance at low external temperatures and against design flow temperatures; COP’s will fall and therefore running costs will increase.

What if we could eliminate the air source heat pump working at these cold external temperatures of say -3°C or -5°C simply by turning off the heat pump when the property requires heating? Using a method to predict what the external temperature is likely to be in the evening / early morning (10pm through to 5am)

Newly built homes don’t have much thermal mass so turning off the heating in the evening isn’t often recommended. As most heat

When you have to keep £15 million worth of

steel at the right humidity for a nearby car plant, you need to think carefully about how you do it. Get it wrong and all that steel attracts condensation and becomes unusable.

That is exactly the challenge faced by the logistics fi rm AV Dawson in Middlesbrough. Their customer, TATA Steel, has an exacting client, namely Nissan, the carmaker. Nissan needs steel to arrive in perfect condition to be able to use it.

In fact, the steel has to be stored in conditions that have 65% humidity or less in the atmosphere. AV Dawson has other warehouses on its sites next to its quays on the

River Tees. The company stores and handles a wide range of goods in warehouses that, typically, have 85% humidity in them.

TATA needed a new low energy solution for keeping steel in good condition near to its customer. Working with their long-term supplier, AV Dawson, they built a new warehouse near to the quay. It covers the area of about three football pitches or about 130,000m.

However, they needed a solution that would keep the warehouse at the right humidity at the same time as maintaining low energy costs.

WHICH RENEWABLEHEATING SOLUTION?The development team considered diff erent renewable heating systems including an anaerobic digester, biomass boilers

and a gas burner. They discounted the anaerobic digester because it was more diffi cult to control. They dropped the biomass option because of its labour intensive nature. The maintenance costs on a gas burner were too high.

Fortunately, Howard Tribick from HT Energy came up with a solution. He recommended using ten NIBE ground source heat pumps connected to Draper air handling units (AHU). Howard calculated that he could provide a consistent humidity to guarantee 65% humidity or less. In addition, he calculated that he could provide a Seasonal Performance Factor (SPF) of 3.65.

In fact, since they commissioned the warehouse in November 2014, the SPF is 3.64 and the average humidity has been 47%.

Gary Dawson, managing director at AV Dawson, said:

How Ground Source Heat Pumps Keep Carmaker’s Steel in Good Condition

“The capital outlay for the heat pumps was greater than the other solutions we looked at. Nevertheless, they are much cheaper over time. Also, the ground source heat pumps give us much better control over our energy costs.”

He continued:“Fitting the NIBE heat pumps

was a ‘no brainer’ for us. In addition to the savings we make, there is nothing for us to do. It is a very low maintenance solution.”

The heating system will save them 1.58 million kWh each year. This means the system will pay for itself within ten years. Moreover, it benefi ts from the commercial RHI (Renewable Heat Incentive) too.

THE HEAT PUMP SOLUTIONThe NIBE 1345/60 kW heat pumps and Draper AHU’s sit down one side of the warehouse. The heat pumps work together through the control system and they collect heat from 70 boreholes dotted around the site. The boreholes are 150 metres deep and sit in an active water table. The ground heat never drops below 9C in winter.

The heat pumps feed 500 litre hot water buff er tanks. Each unit has electric back up. The AHU’s contain heat exchangers, and louvres control the airfl ow. Each system can either recycle internal air, or take it from outside, depending on the local weather conditions.

Solar panels on the roof provide 220 kWh for the heat pumps, lighting, doors and cranes. There is a generator outside as an emergency back-up.

Neil McShane, facilities manager at AV Dawson, explained how well the project worked:

“From being a building site to ‘handing over the keys’, this project took 208 days to complete. And, there has been no disruption for TATA Steel and Nissan.”

The project has had a big impact on how Nissan perceives TATA and AV Dawson. The new warehouse has set a new standard for warehousing in

the automotive industry and at TATA. Using heat pumps like this gives confi dence in the quality of the steel Nissan buys from TATA, as well as confi dence in their capacity and ability to grow with their customer.

IMPACT BEYOND THE SOLUTIONThe warehouse is impressive. It is huge. Howard Tribick’s NIBE ground source heat pump solution is remarkable too. It is a showcase for how forward thinking businesses are using heat pumps to control and lower their energy costs in the UK. And, their impact goes beyond mere costs. In this case, they are having a wider, positive business impact on the customers too.One of the ten NIBE heat pump units

The heat pump industry needs answers to some big questions – and for installers and contractors in particular, some understanding of what this all means to their businesses. This is why visiting this year’s Heating and Renewables Roadshow is more important than ever: with over 60 leading suppliers, manufacturers and trusted experts across fi ve locations all on hand to help with your business needs.

Making the decision to take time off work is always a diffi cult one, with client pressures taking priority. However, the unique regional format of the Roadshow eliminates a lot of the concern for visitors who might not want to take the time to travel to attend an exhibition. Instead, the Roadshow travels to them, making it fully accessible to installers, contractors and specifi ers all over the country.

Car parking is completely free of charge, courtesy of sponsors Glow-worm.

This year’s Roadshow will showcase some of the most innovative heating and low carbon technologies. With energy prices fl uctuating, the importance of how homes and workplaces are heated has been sharply brought into focus and so this will feature heavily alongside renewables at the Roadshow.

Equipping visitors with the necessary knowledge to increase profi ts and improve product specifi cations is at the very heart of the Heating & Renewables Roadshow, and we’ve worked hard to develop a comprehensive, stimulating – and free - seminar programme.

Key-supporting organisation, TrustMark, leads the way with valuable advice, whilst

the seminar programme is brought to you in association with the Roadshow’s four Knowledge Partners: REHAU, Stroma Certifi cation, Edmundson Electrical and Sustainable Building Solutions. Plus, a fi fth specialist product theatre featuring Gas Safe Register. Added to this is the impressive list of confi rmed speakers from trade bodies across the industry, including Ground Source Heat Pump Association, Sustainable Energy Association, Microgeneration Certifi cation Scheme, HETAS, Building & Engineering Services Association, Electrical Contractors’ Association and the Heating & Hot Water Industry Council.

With added theatres, maximum industry participation and many speakers presenting their considerable expertise, never has there been more compelling educational content and hands-on demonstrations for Roadshow visitors.

Heating & Renewables Roadshow: Bringing Trusted Experts To YouIn the last few weeks there have been mixed messages from Government on its green agenda for the UK, making life anything but straightforward for the renewables industry. In particular, there is much uncertainty and confusion over key legislation, subsidies and funding.

Waterloo helps fulfi l cricket dreamWaterloo Air Products is helping to build a brand new dedicated cricket clubhouse on Victoria Embankment at the Meadows Recreation Ground in Nottingham.

Called the Field of Dreams Project, the new clubhouse is the vision of the Trent Bridge Community Trust to leave a true legacy from the Investec Ashes Test Series at Trent Bridge in 2013 and 2015.

The children created comic strips showing what it takes to be an ‘eco-super hero’.

Now in its third year, the challenge for children in primary schools is to show how they can help save the planet. Children on the shortlist came from 26 schools in and around Birmingham and Manchester. They went to The Crystal* in London on 24th June for the prize giving ceremony.

Armstrong Fluid Technology director, Steve Cooper, said:“The prize giving event for our annual School’s Competition

provides a great focus for looking back at all that has been achieved over the past year and setting our sights on the future.”*The Crystal is one of the world’s most sustainable buildings.
