P r e s i d e n t ’ s M e s s a g e

Welcome to the 2017-2018 ASHRAE meeting year. The board and I are looking forward

to an exciting year of monthly meetings, YEA (Young Engineers in ASHRAE) events,

golf outing and our new group, (WIA) Women in ASHRAE. This new group will give the

women members of ASHRAE an opportunity to get together and support each other.

Thank you Lauren Abercrombie for offering to organize the WIA group.

Several board members recently attended this year’s (Chapters Regional Conference)

CRC event in Roanoke, VA. The CRC event gives us an opportunity to meet with the

officers of surrounding chapters located in Pennsylvania, Maryland, DC, and Virginia.

During the three days of meetings, we had an opportunity to learn what types of events

other chapters are offering their members as well as how successful each is. While I

consider our events to be on par with what is being offered by other chapters, I know

that we could be attracting more people to the meetings. As someone who has attended

a majority of the meetings for the last few years, I have enjoyed both the social and

technical aspect of the meetings. I have had a chance to meet a lot of people that I can

now reach out to for support or reference when needing specific information.

Please remember that the ASHRAE Philadelphia Chapter belongs to all of our

members. The chapter is here to support all of our members in the HVAC industry.

Please feel free to reach out to me and all the other board members with any

suggestions or ideas that will make the meetings and events more applicable and

valuable to you.

September Meeting Information

Thursday, September 14, 2017

Presentation Summary

What You Don't Know - But Need to Know About Total Energy Recovery Wheels

to Enhance Your Mechanical Designs and WOW Your Clients:

Lessons Learned Over 40 Years

The following topics will be discussed:

o The power of proper engineering due diligence – how critical duty total energy wheels have saved the Johns

Hopkins School of Medicine over $100,000,000, enough to pay for 1.5 medical research laboratories

o Total energy recovery wheels can be applied to most laboratories and comply with ASHRAE 62 Addendum K

producing better IAQ then in most offices and schools.

o A total energy wheel must be BOTH an energy recovery device AND an indoor air quality device which does not

transfer contaminants back to the occupied space ? otherwise use a recirculation damper – it is cheaper!

o Recent ASHRAE 62 Committee clarification – recirculated air does not count as outdoor air so a recovery wheel

purge section should be utilized.

o AHRI RER – why the parasitic fan energy associated with high wheel pressure loss should be avoided –

specify high latent performance and low pressure loss.

o Avoiding frosting and condensation conditions - why high latent performance is key.

o Proper economizer control significantly increases energy savings - don’t go cheap.

o Combining these total energy recovery best practices to form advanced desiccant based systems for neutral air and

low dewpoint applications – benefits recognized.

ASHRAE Philadelphia Corporate Sponsorships Available

The Philadelphia Chapter invites your company to join as a Corporate Sponsor for the 2017-2018 year. Your

firm’s participation in this program would enable us to make a wonderful donation to ASHRAE Research Promotion

which includes over $ 1.5 million in local research funding.

Corporate Sponsors are listed on our web site, in our newsletter, and in our annual directory. They receive free copies

of our directory and recognition at all of our events. With the ease of one payment, you may get all this, as well as free

dinner tickets good for our monthly meetings, and make a valuable contribution to ASHRAE Research at the same

time.

Since not all companies have the same financial capabilities or quantity of employees, we offer a few different levels of

corporate sponsorship. Each level will receive the same types of benefits, with some differences in quantities and

discounting.

We hope you will decide to join us as a Corporate Sponsor. If you are interested, please email us at

philachapter@mail.ashrae.org. The Board of Governors thanks you for your continued support of ASHRAE. We hope

that this year is successful for your firm.

Using Variable Frequency Drives with Steam

Understanding Variable Frequency Drive (VFD) Applications for Centrifugal Boiler Feed Pumps

Reprinted courtesy of Shippensburg Pump Company, Inc.

This bulletin is intended a brief overview for steam system applications where variable frequency drives (VFDs) are used

for controlling centrifugal volute style boiler feed pumps. It is important to note that a turbine pump, by its inherent

design, and operational characteristics would not fit into this discussion.

Over the past few years, Shipco began coupling the use of a VFD with the use of an automatic flow control valve to

maintain a flow at a constant pumping rate, while varying the speed of the pump motor to satisfy varying boiler operating

pressures, and simultaneously meet the ASME (American Society of Mechanical Engineering) code. These various

operating pressures are part of a growing trend in our industry with respect to efforts surrounding “net zero” energy

building designs and reduced energy operation procedures (e.g., weekend shutdowns and night setbacks).

Simply stated, boiler feed pumps are sized to meet the flow requirements of boiler design loads and overcome the

internal operating pressure of the boiler, in addition to overcoming all the pressure drops of the feed piping and feed

control valves. Modern boilers are manufactured to ASME standards and this has resulted in standardization of specific

boiler design pressures. The specific design pressure that seems to continually be of concern to feed pump

manufacturers is the 150 PSIG design boiler. Boilers of this design pressure are typically fitted with a pressure relief

valve that is set for 150 PSIG. Consequently, this is not the typical operating pressure of most boilers, even when they

are designed to operate at 150 PSIG. Boilers operate over a wide range of pressures. It’s when a boiler is designed to

operate at one pressure, and then operates at a significantly different pressures, that causes centrifugal pump

manufacturers major headaches (an lots of warranty claims). This article will not go into an in-depth discussion of steam

space or steam quality. It is relevant to point out that any changes in boiler operating pressure can adversely affect the

operation of other components in a steam system such as: traps, regulators, pipe sizing.

A basic understanding of centrifugal pump flow characteristics and centrifugal pump curves is assumed for

this discussion. Pumps perform at specific conditions based on pump curves and flow characteristics required for

steam system performance. An example following the outlined characteristics is described as follows:

100 BHP boiler

Operating pressure = 100 PSIG

Pressure drop of piping and valves in the feed system = 15 PSIG

Pressure drop of automatic flow control valve = 5 PSIG

Boiler relief valve set from factory at = 150 PSIG

From the information given, we know that the evaporation rate of a 100 HP boiler is .069 GPM/HP, hence 100 times

.069 or 7 GPM. Doubling the evaporation rate to determine a pumping rate for on/off pumps is an accepted industry

standard for most boilers. Based on this formula, the recommended boiler feed pump pumping rate would be 14 GPM.

Furthermore, the ASME code dictates that the pump discharge pressure must exceed the boiler relief valve set point by

at least 3%. Using the 150 PSIG relief valve setting, plus the 3%, we get 154.5 PSIG. Depending on actual operating

pressure, we may need to add in a safety cushion for any piping pressure drop (i.e., friction loss) and flow control valve

pressure drop to arrive at the total pump discharge pressure required.

Additionally, the pump HP requirement is determined by reading the pump curve, typically available from the pump

manufacturers’ catalog or website.
