1.5 Changes vs the specific verification protocol

There were not significant changes to the protocol: the proposed schedule were followed.

2. DESCRIPTION OF TECHNOLOGY AND APPLICATION

2.1 Summary description of the technology

The project relates to the development of an innovative product-service offer that intends to revolutionise

the hydronic market. SmartCIM value aims at transforming water distribution valves from simple actuators

of the Heating Ventilating Air Conditioning (HVAC) distribution systems into smart active nodes that can

control with great accuracy quantities flowing through and interoperate with other components of the

system (coils, thermostat, pumps) in such a way as to deliver the exact amounts of heat/cooling in each

zone served with minimal amount of water and losses. In a nutshell, smart valves shall enable smart,

efficient HVAC plants.

The new valve technology is based on the deep integration of sensors and actuators; software eco-system

makes the valve interoperable with other hydronic components, enables seamless implementation of

advanced controls and allows monitoring from the internet. SmartCIM is among the first valves with IoT

(Internet of Things) features, including monitoring/user feedback on mobile devices (at present there are

only few companies manufacturing valves which can be run by Internet).

2.2 Application and relevant alternative

In HVAC plants heating and cooling are regulated by balance of heat/cool load served from the heat/cool

terminals. In such conditions, it is possible to regulate the flow to the terminals, opening the valves, while

reducing pump velocity, as none of the terminal requests a different power level. The saving is less when

the thermal load is unbalanced, as one or more of the rooms served by the plant would need more power

than the others, so a certain degree of dissipation will occur in the terminals serving the less requesting

rooms, where the valves will be partially closed to reduce the flow.


ETV02/2017

At present PICVs (Pressure Independent Control Valves) represent the most advanced and relevant

alternative and the state-of-art; they feature an internal mechanical device (diaphragm) to regulate the

flow rate regardless of pressure fluctuations. An electric actuator modulates the flow rate in response to

the Building Management System (BMS). Then PICVs are not active and control elements, but rather

passive actuators operated by an external BMS control, with self-adjusting mechanical adaptation to plant

conditions. PICVs allow indirect control of HVAC plants, where actuators (generators, valves, pumps, fan

coils) are regulated to achieve a target set point of ambient temperature in each zone where a thermostat

is on. Actuation is controlled by the BMS using room temperature as the measured output. Control is

indirect because there are two systems in between actuators and output, i.e. the building and hydronic

plant with their characteristics. This creates lags and imprecision in control resulting in losses and

instabilities. A typical situation occurs when valves are opened until air reaches set point. When differential

over-pressure (>2,5bar) occurs in the plant, valves have trouble maintaining proper flow and closing against

that pressure. Under such common circumstances, valves could take up to 30 minutes to respond to

flow/temperature changes. Meanwhile, a lot of chilled water passed through the system, causing

unnecessary operational costs. Another typical situation occurs when actuators are not precise enough to

reach set point temperature and control bounces on and off until the target is reached. Such ‘hunting’

causes discomfort and unnecessary losses.

On the other hand the control enabled by SmartCIM is direct and provides much richer information, since

each valve measures flow rate, temperature and heat flow passing through, giving following advantages:

• control of flow rate is direct for each valve, thus giving the possibility to perform optimal zone control

with minimal amount of water (savings in the pump) in any service conditions

• combined control of valve-fan coil is implemented, fan speed can be adjusted depending on flow rate

• heat flow delivered in each fan coil/radiator is measured by the valve, thus allowing refined analysis of

consumption in each zone served

• flow rate and pressure measured in each valve contain detailed information on the operation of each

branch of the hydronic plant, suitable to allow early detection of drifts or malfunctioning

• flow rate measure in combination with wireless communication enables a smart commissioning

procedure where the target flow rate can be set up in less than one minute using the actuator as the tuner.

The valve becomes an active node of the distribution plant that enables smarter controls and demand

management strategies.

2.3 Environmental benefits

Benefits in application are substantial in terms of electrical power savings by: 1) drastically reduce power

for pumping; 2) cut parasitic losses due to membrane pre-load in PICVs.

At present, no other environmental benefits can be considered.

3. EXISTING DATA

3.1 Existing data and evaluation of the need of specific tests

Since at the beginning of the verification process no fully reliable performance data were available, the

Proposer and the Verification Body agreed to develop specific test plan in order to verify and validate the

claim. In the next chapter it is described the summary of the agreed test plan.


ETV02/2017

4. DESCRIPTION OF LABORATORY TEST ON EQUIPMENT

4.1 Description of test elaboration and installation of equipment

The tests were organized and managed by ENERSEM srl, a new spin-off company (founded 2016) which

develops broad-spectrum innovative solutions in the energy sector, on the basis of expertise generated

from research projects at Politecnico of Milano.

As stated in verification protocol, no official method are available for the type of parameters which were

verified. The test methodology was developed by Enersem S.r.l. [see ANNEX 3. TEST

PROCEDURE_SMARTCIM_FINAL] and performed by ReLAB laboratory, a well equipped Laboratory of

Politecnico, located at new Department of Energy, Politecnico of Milano-Bovisa. ReLAB is accredited for UNI

CEI EN ISO/IEC 17025:2005 [See also ANNEX 3 and ANNEX 4 of Specific Verification Protocol for

accreditation details].

The panel with all equipment to be tested (the complete hydraulic scheme) were prepared by Cimberio

R&D Department and was placed in the climatic chamber maintained at a temperature of 25°C± 2 °C.

The hydraulic scheme of circuit, shown in figure 2, consists in: 3 parallel branches in which 3 pressure

independent control valves (PICV) used for the comparison, 3 smart control valves (SmartCIM) e 3

flowmeters were installed. A series of manual valves allowed the selection of the pressure independent

control valves (PICV) instead of smart control valves (SmartCIM) and vice versa. While hydraulic lines,

between the branches, and further manual valves allowed the connection in series of the flow rate meters.

The 3 flowmeters allowed independent flow rate measurements of each branch. These measurements

were not used as reference.

Figure 2 test facility:


ETV02/2017

The reference flowmeter was installed in place of the stub pipe; while the hydraulic circuit was filled with

tap water through the filling tap and pressurized until 3 bar. The pump and the electric board were

“energized” through “metered” sockets. A temperature probe (PT100) was installed for monitoring the

water temperature within the hydraulic circuit during the tests; two differential pressure gauges were

installed close by the two balancing valves: one for measuring the pressure drop at balancing valve M1; the

other one for measuring the pressure drop at the 3 branches (M2).

4.2 Main objectives of tests and description of instruments

The main objective of the tests is to assess the performances of the SmartCIM valve compared to the Best

Available Technique (BAT). At present the Pressure Independent Control Valve (PICV) valve is the only

available best technology for commissioning and tuning of HVAC plants.

At the beginning of the experimentation the Proposer Cimberio had to choose a PICV valve suitable to be

compared with the new SmartCim system. Among different manufacturer datasheets, they checked the

technical characteristics of each valve and mainly the value of start-up pressure: this parameter shows the

minimum pressure needed in the pipe at which the PICV valve starts opening and working in the right way,

giving constant flow rate in a specific range. As it can be seen in different datasheets, the start-up pressure

value is quite different for all manufacturers, ranging from 16 kPa to 50 kPa and depending on the valve

size and actual flow rate inside. For this reason the Proposer decided to use, as a comparison, a PICV valve

of his standard production, i.e. model 717HF DN15 (with a nominal start-up pressure value of 13-19 kPa),

corresponding to the lower value of previous range: so the tests did not aid the new SmartCim system in

any way, as they were run against a PICV valve with one of the minimum head loss among the competitors.

All datasheets used for comparison are available upon request.

Main data of tested valves are listed in table 2:

Table 2: tested valves

Denominazione Internal lot Type – Nominal flow

SmartCIM valve 1717 SmartCim 15 – 600 l/h

PICV valve 1440 Cim 717HF 96 – 483 l/h

The comparison was made by monitoring the electrical power requested among 3 different scenarios:

A) PICV valve, the BAT and also the reference BASELINE, was compared with scenarios B) and C) that

performed a lower electric power, mainly the last C).

B) new SmartCIM valve with a steady flow rate given from circulation pump

C) new SmartCIM valve with advanced control strategy by automatic adjustment of pump rotational speed

All comparisons have been made among scenarios B) and C) towards scenario A) i.e. the BASELINE, which is

so the baseline for each parameter.

To better compare the two different technologies in different working conditions, a total of 28 tests were

carried out, choosing rate that are representative of two different terminals at two levels of nominal flow

full load, i.e. Q nom 650 l/h and 1230 l/h. Then 3 partial flows were tested too, to appraise the savings at

terminal partial load, so the equipment was tested at 100%, 75%, 50%, 25% for each Q nom: in this way all


ETV02/2017

the possible plant conditions were simulated and the results of tests can give a complete picture of the real

working of a standard HVAC plant: for better understanding when speaking of Q nom, its value is referred

to total flow rate measured by main Fr instrument, that measures the sum of flow rate of the three valves,

i.e. in each valve flows 1/3 of total Q nom.

As described in Test Procedure SmartCIM 20170710, the following devices, instruments and related

variables were utilized and measured:

- 1 variable speed pump with remote control;

- 2 manual balancing valves for the local pressure drops; only M1 is regulated, while M2 must be

always shut;

- 1 Electric board located on the back of the panel in which also the control was included;

- 2 taps: one for filing and the other for emptying hydraulic circuit;

- 1 reference (laboratory’s) flowmeter, Fr

- 2 reference (laboratory’s) differential pressure drops , Dp1, Dp2

- 2 reference (laboratory’s) energy meter, EE1, EE2

- 1 reference (laboratory’s) water temperature (PT100)

- In controlled ambient air (temperature, humidity and pressure)

All references of instruments are reported in final test report page 18 released by RELAB [see ANNEX 4.

TEST REPORT – ReLAB - ENE-RE-C0217-RP-01_firmato].

5. EVALUATION

5.1 Evaluation of test results

The complete campaign of tests has been carried out by RELAB Laboratory on July 12-14th 2017 according

to the standards mentioned in “TEST PROCEDURE_SMARTCIM_FINAL”.

The first step was the VERIFICATION PHASE consisting on checking the 3 flow rate meters F1, F2, F3 in

comparison with the reference meter Fr. To simplify this test, it was set up a special distribution network

by opening and closing the manual valves, in order to send the same flow rate in each flowmeter, one

another put in series, as described in table 1 page 8 of final TEST REPORT.

The tested mass flow rates were 100, 150, 300, and 450 l/h for each flow rate meter. These checks were

repeated twice with a total of 8 tests. The whole set of checks showed acceptable values of measurement

error, measurement stability and uncertainty of measure also for commercial meters, not periodically

calibrated, as showed in tables 4, 5 and 6, see page 11-12 of TEST REPORT final by RELAB.

The second step, after this preliminary Verification Phase, the most important one, was the POWER

REDUCTION ASSESSMENT whose scope was to measure the real performance of the new technology

SmartCIM in comparison with present BAT (PICV valve). To better compare the two different technologies

in different working conditions, a total of 28 tests were carried out. The test scenarios identified as A), B)

and C) are described in previous paragraph 4.2.

In this Verification Report are enclosed only the main results of tests. In final test report released by RELAB,

[ANNEX 4. TEST REPORT – ReLAB - ENE-RE-C0217-RP-01_firmato] is enclosed the complete results and data

elaboration.


ETV02/2017

The results of final test report show that the new SmartCIM valve can save electrical energy, decreasing

the power requested by circulation pump. It must be added that the most power saving is obtained at low

flow rates into the distribution network of a HVAC plant.

5.2 Verification parameters and tests results

In the following tables 3a) and 3b) are reported the main parameters monitored and used to compare the

different scenarios A), B) and C) as part of this verification. The environmental parameters, i.e. measured

POWER REDUCTION ASSESSMENT PHASE

During this phase it was estimated the monitored electrical power reduction of the circulation pump among

the scenario A) as the Baseline with PICV valve and the other two B) and C) with SmartCim.

All comparisons have been made among scenarios B) and C) towards scenario A) i.e. the BASELINE, which is

so the baseline for each measured parameter.

The Energy Saving Assessment was done for the minimum nominal flow rate of 650 l/h, see Table 4 and for

the maximum nominal flow rate of 1230 l/h, see Table 5 according to the formulas reported in the section

“Calculation Method” of Test Procedure SmartCIM. In tables 4 and 5 is reported the monitored electrical

power of the circulation pump among the three scenarios.

Table 4: Pump Electrical Power at different percentage for minimum nominal flow rate 650 l/h

The most interesting comparison is between Scenario C and Scenario A, as it will have big energy saving

impact on a standard HVAC plant, especially during design, construction, commissioning and running

phases. As it can well be seen, there is a very big amount of power saving (in percentage) between the

Scenario C and Scenario A, variable from 27% up to 75% at minimum flow rate and from 18% up to 83% at

maximum flow rate, depending on actual flow rate through each valve.

This huge saving, mainly at lower flow rate which is a standard working condition for many plants, is

generated by the possibility of reducing dramatically the rotational speed of the pump, so decreasing the

electrical power, but maintaining the necessary right flow rate through the SmartCIM valve. Moreover this

valve has a very low pressure drop due to innovative internal shape, about 1/6 of a standard PICV valve.

5.3 Evaluation of uncertainty and stability of measures

Each test was performed under steady state conditions. Once each hydraulic condition (flow and pressure)

was reached and stabilized, then measures were taken for 5 minutes. One measurement every 2 sec, which

means 30 measures per minute, was done for each of the reference instrumentation.

The uncertainties of measurement shall not exceed the values specified in Table 6, based on Standard BS

EN 14511-3:2013: Air conditioners, liquid chilling packages and heat pumps with electrically driven

compressors for space heating and cooling. Test methods.

5.4 Test run conditions and quality evaluation

The test run conditions managed by ReLAB were carefully checked during VB Certiquality quality audit step

and finally evaluated by Certiquality experts as consistent with test procedure [see ANNEX 3.

TESTPROCEDURE_SMARTCIM_FINAL] .

According to ETV GVP principles all the tests were run by using recognized International Standards (ie ISO,

ASTM, EN, UNI, etc) or in case relevant standard were missing by using drafts or GLP (Good Laboratory

Practices). The requirements of tests are described in the above-mentioned procedure.


ETV02/2017

Data storage, transfer and control must be done in accordance with the EU ETV General Verification

Protocol (Version 1.2 - July 27th, 2016 Corrigendum 1 - October 15th, 2016) and furthermore follow the

principles of EN ISO 9001 Quality management systems – requirements (International Standardization

Organisation, 2008). Data management shall enable full control and retrieval of documents and records.

The ReLAB Laboratory is ISO 17025 accredited. A complete evaluation and audit made by Certiquality

confirms that the Laboratory test plans, procedures and manual are consistent with the requirements. The

audit were carried out by a qualified quality auditor of Certiquality with a large expertise of analytical

laboratories.

6. VERIFICATION RESULTS

6.1 Performance claim

On the basis of test results, the initial claim can be confirmed, mainly due to power saving values, as

already stated in paragraph 5.2, ranging, between the Scenario C and Scenario A, from 27% up to 75% at

minimum flow rate and from 18% up to 83% at maximum flow rate, depending on actual flow rate through

each valve.

As it can be seen, the highest power saving is gained at minimum flow rate, i.e. 75% saving at 153 l/h and

83% at 311 l/h. This fact is due to the specific characteristic of a pump which gives the maximum power

saving at the minimum flow rates: this is often a common condition in the distribution network, mainly in

the middle seasons when the HVAC plant do not work at full load.

This situation is well known by designers and plant managers, who would have the possibility to adjust the

main working parameters in a smooth continuous way and a wide range of heating or cooling loads.

Another interesting characteristic of SmartCIM is the very low pressure drop inside the valve, due to special

internal shape, that means a total head loss about 1 / 6 against a standard PICV: this aspect reduces,

besides power of pump, also the mechanical stress in distribution networks with advantages for

maintenance operations. These results are reported in tab 3a) and 3b) for operational parameter Dp2,

which measures the head loss of different valves and running conditions.

For above reasons, this new valve SmartCIM can be considered among the devices to be kept into

consideration during the design of a new plant or in case of revamping of an existing one. Of course the

present performances of this new device shall be deeper investigated in all type of installation to better

state the real advantage of this new technology.

6.2 Conclusions and considerations

The tests made by ReLAB Laboratory have simulated some usual conditions of standard HVAC plants

working with different flow rates, mainly at partial and low mass flow.

The results given by Test Report show that the new SmartCIM system can be considered an energy saving

technology, able to lower the electric power of the circulation pump into a distribution network. As seen

before, the most power benefit is obtained at low flow rates, which can be a common situation generated

by a different thermal load onto a side of a building (i.e. South oriented) or during the middle seasons.

Then as a consequence of reducing the power of pumping station, also the running costs of a HVAC plant

slow down.

At present all measured parameters and saving results are tightly linked to this specific hydraulic facility

used in ReLAB test and nothing can be told about other type of installation.


ETV02/2017
