Initial admission audit


Selection of units to be tested


EUROVENT CERTITA CERTIFICATION shall select units to be tested based on its evaluation of the declaration file LCP-1 communicated by the Applicant.

Within the programme, tests may be conducted under the following procedures:

Scheduled tests in qualifying procedure Scheduled tests in surveillance procedure Penalty test in surveillance procedure Complaint test

Eurovent Certita Certification is responsible for the selection of a unit for testing and may select any unit as defined below.

Selection from the existing available stock is preferable, even if only a single unit is available. If no stock is available a selection will be made from the Participant production schedule within a 6-month period.

For high capacity units, if a declared standard unit is not available, Eurovent Certita Certification can ask the list of units ordered or recently sold by the manufacturer, accompanied with the associate data from their selection tool. Eurovent Certita will select a model among these units

For the penalty tests, Eurovent Certita Certification shall select the additional units from the failed range, if applicable.

All models presented by the Participant shall be listed together; however only basic models shall be included, various options shall not be counted.

The Participants are free to group models in commercial ranges in accordance with their own rules.

The required number of units for scheduled tests is defined as the highest number of tests in Table 8 corresponding to the number of basic models or the number of commercial ranges.

Example: if a Participant presents 21 ranges with 120 BMG, he will be required to submit 5 models for testing although according to the number of BMG only 4 tests should be needed.

When Participant chooses to certify models in option (except for water-cooled units above 1500 kW), the total number of BMG and ranges includes as a single group, units in the regular scope & units in options.

For the option “air-cooled units above 600kW”, at least one unit over 600kW shall be selected for testing

For the option “water-cooled units above 1500kW”, one supplementary unit above 1500kW shall be selected for testing.

Note: The supplementary tests for the water-cooled units >1500kW is maintained for the qualification campaign of this option. It will be removed after the qualification campaign and will be managed as the other options.

For all options, except water cooled high capacity units, Eurovent Certita Certification will choose a number of selected units representative of the share of optional units in the global number of units.

If an option can’t be tested during the test campaign, ECC can ask a witness test per option covering the missing options (when possible) among the witness tests to submit (if the witness test option was taken).

When the witness test cannot cover a missing option (or if the Participant did not take the witness test option), one unit per option can be tested every 2 years for the missing options (when possible).

For the Indian option, ECC will calculate the number of “ISBMG” among the Indian models.

“ISBMG” Definition: “A ISBMG is defined as a family of chillers using the same compressor model family or combination of same compressors from the same compressor model family.”

These “ISBMG” are different from Eurovent LCP Basic Model Group.

For the Indian option, the number of selected unit shall be equal to 30% of these “IS_BMG”.

Example : 5 IS_BMG ➔ 1.5 unit ➔ 2 selected unit.

Note: For the first years, ECC will consider the number of selected units required for the “Indian Option”, among the global number of selected units for the testing campaign.

The principle of the witness tests:

The tests have to be done in the manufacturer laboratory with the attendance of the client or designated representative.

The tests must be done with an ECC certified unit (with or without options) for a standard conditions or non-standard conditions available in the software tool (under certification/certified).

The conditions to take the option:

The manufacturer has to choose the option “certification of the software tool” for 2019. The manufacturer needs to have his own laboratory. The references of the unit have to be mentioned clearly in the witness test reports. The report

has to be signed (the name and signature) by the client who attended the test. The tests have to be done according to the TCR and the mentioned standards if applicable

(EN14511, EN 14825, ISO 9614, ISO 3744, ISO3741, IS16590, SASO 2874). An acquisition time of 15minutes is accepted.




In minimum a full load performance (capacity and efficiency) must be mentioned in the test report.

All the type of units, tested in the Participant laboratory for “witness test”, which are in the scope of the programme and >100kW, will be accepted.

The manufacturer must provide all the witness test reports as agreed: ½ of the total number of the witness reports before end of June ½ of the total number of the witness reports before end of November If the agreed test reports were not submitted according to the above deadlines, the removed

tests will be added the next year campaign. The performances indicated in the witness tests will be verified with the software tool and if there

is a failure, the rerate defined in the APPENDIX E (software tool) will apply.

Depending on the total number of the tests to be performed for 2019, between 1 and 4 tests will be removed. In return, the manufacturer has to provide between 3 and 14 witness test reports with the corresponding numbers of points (in total) according to the below table.

The number of test points shall be determined in accordance with the number of application ranges (air-conditioning, cooling floor, medium brine, low brine, low temperature, intermediate temperature, medium temperature, or high temperature) applied for by the Participant.




If the application ratings are entirely included within one application range, the selected models shall be tested at the corresponding conditions stated in the APPENDIX A.

If the application ratings cover totally or partially other application ranges, the selected models shall also be tested at the corresponding Standard Rating conditions. In this case, if the Standard Rating conditions cannot be reached, they shall be replaced by one application rating condition in the range.

In addition, all the selected models shall be tested at:

• One application rating condition (selected by Eurovent Certita Certification) with the exception of air source heating-only heat pumps for which two points at +7°C and +2°C can be required.

• Part-load condition(s)

In any cases:

Maximum two Eurovent applications shall be tested Maximum three seasonal efficiency in heating (SCOP/η) and two seasonal efficiency cooling

(SEER/η) shall be tested, among different climates and declared application (Low or Medium temperature) and declared water control (WF/FO, VW/FO, FW/VO or VW/VO).

The chillers will be characterized by two Seasonal Efficiencies for Cooling:

SEER (and ηsc) is applicable for comfort chillers, reversible or not. SEPR is applicable for Low,Medium and High temperature process chillers

When a unit with 2 declared ηsc is selected, Eurovent Certita Certification will choose to test randomly one application (12°C/7°C or 23°C/18°C).

Eurovent Certita will choose randomly:

one part load condition for each application (SEER, SEPR if declared) one auxiliary mode among the four modes (Poff, Psb, Pto, Pck) in cooling mode.

in addition to the nominal efficiency linked to each application.

These performances shall be tested if declared by the Participant.

These conditions concern Reversible Chillers and Heat Pumps.

For a declared SCOP and declared ηs (seasonal efficiency in Heating), the following tests shall be carried out: for one declared application, low or medium temperature.

Nevertheless, the Participant has also the possibility to ask for all the part loads from the start.

All the conditions are detailed in EN 14825:2018 Standard.

In order to cover all the applications and all the climates declared with a relevant number of tests, the following rules shall be applied.

At least, one condition from ISEER will be tested per unit. If needed, the manufacturer can ask additional ISEER part load points.

Only one point (randomly selected) will tested by selected unit.

The compressor type, the inverter type and the number of compressors have to be checked before the test (independent lab and part lab) by the laboratory according to the information declared by the manufacturer.

From 2019, ECC can validate the manufacturer’s laboratory based on the tests done during the Participant laboratory tests.

A temporary certificate:

If the Participant laboratory is already recognized by ECC, ECC will give a temporary certificate which mentions:

The limit of the laboratory: corresponding to the maximum power tested for air cooled and water-cooled units for each Participant.

If the manufacturer wants to increase the limit in the certificate, a test must be done with a unit which can reach the proposed limit.

End of validity of the certificate: 30th September 2019 (the same validity date than the diploma ECC for the products).

Official validation of the laboratory:

During the 2019 test campaign, a test (thermal and acoustic points) among the Participant laboratory tests can be tested per manufacturer using:

The measuring instruments of the independent laboratory The measuring instruments of the Participant laboratory by the independent laboratory’s

technicians.

A comparison of the both test reports can be done by ECC. If there is a non-conformity, the manufacturer can analyse it and propose a corrective action.




Tests at the independent laboratory


Before testing, the laboratory shall check the product against the information declared in the technical datasheet to ensure that the unit corresponds to the selection.

The laboratory shall not perform the test and contact EUROVENT CERTITA CERTIFICATION:

one of the information is not compliant with the technical datasheet (see technical APPENDIX A),

one of the units appears damaged

EUROVENT CERTITA CERTIFICATION will contact the Applicant to give instructions regarding further actions.

Laboratory

All units with cooling or heating capacity at Eurovent Certita Certification Standard Rating Conditions below the following values shall be tested in an independent laboratory approved and under contract with Eurovent Certita Certification. The choice of the independent laboratory is made by Eurovent Certita Certification for:

Up to 100 kW for Air-Conditioning & Cooling floor Applications

Up to Pdesignh = 70 kW for low temperature and/or medium temperature Applications

Units with higher capacity shall be tested either in an independent laboratory or in a Participant laboratory (approved by Eurovent Certita Certification) by an independent agency (selected by Eurovent Certita Certification) following the procedures specified in the appendix A.

Units shall be installed in the test facility in accordance with the Participant's published installation instructions. A contact person shall be designated by the Participant to provide whatever support is required during the test.

Special instructions shall be sent with the unit. The laboratory cannot be held responsible for a wrong installation if the Participant didn’t provide these specific instructions.

Notification to provide equipment for testing

Eurovent Certita Certification shall notify the Participant of the intent to test specific models in accordance with the requirements of this programme. This notification shall request delivery of the units, the duly completed Technical Data sheet, the order and all relevant installation and operation manuals.

Selection, shipment, handling of test unit and return

Eurovent Certita Certification shall arrange for a particular unit to be obtained from the Participant's production lines, or any stocking point, and delivered to the laboratory.

The independent laboratory shall have the responsibility of un-crating, handling, testing and re-crating the unit for shipment.

A contact person shall be designated by the Participant to organise the shipment to the laboratory, the laboratory shall inform him when the test is completed.

The Participant shall ship back the unit after 2 months after the reports sending when:

The result of the test is passed

The rerating is accepted by the Participant

Or the result is failed but the second test is ordered on another unit.

Time limitation of acquisition of unit

If the laboratory is unable to obtain the unit and the relevant documentation within the time limitations defined by Eurovent Certita Certification (see APPENDIX C) the Participant shall be notified that the list of its products will be withdrawn from the Website for one year.




Eurovent Certita Certification may choose not to discontinue the listing when a Participant provides him with a definite and acceptable date of his next production.

Participant's representatives

• Testing at an independent laboratory

A Participant’s representative can make the start-up of the unit. In that case, the Participant shall inform Eurovent Certita Certification that he wants to attend the start-up, and the laboratory shall inform the Participant about the date the unit will be installed.

Only the laboratory personnel shall be permitted to install and check out test units. The procedures used shall be in accordance with the Participant's installation start-up and service instructions. No Participant's personnel shall be permitted in the laboratory test facility before, or during the test except the personnel needed to operate.

In case of damage the laboratory personnel shall be allowed to supply necessary tools for repair of the test sample before the test. If the unit is not repairable, it shall be replaced by the Participant within one month for units below 100 kW and three months for units above 100 kW.

• Testing own products at a Participant laboratory

Tests shall be performed by an independent agency, selected by and under contract with Eurovent Certita Certification. The same procedure as for testing at an independent laboratory shall be applied except that the Participant’s personnel shall not be permitted in the laboratory test room facility. The test requirements in Participant laboratory are given in the APPENDIX A.

• Testing competitor products at a Participant laboratory

Tests shall be performed by an independent agency, selected by and under contract with Eurovent Certita Certification. The application forms shall be checked by an independent agent and shall not be disclosed to the competitor laboratory. Problems of confidentiality shall be solved by a mutual agreement between Participants.


The tests shall be conducted at the conditions stated in APPENDIX A.

Initial test failure

If any functional component is inoperative, or the unit is damaged and cannot be repaired and tested at the Laboratory, then it is considered as a “initial test failure".

If the unit defrost cycles at +7°C outdoor temperature are too short to perform acoustic performances testing the unit is considered as a initial test failure.

It is also admitted that defrost during the thermal or acoustic test at +7°C is “initial test failure” when:

According to the standard:

• auto-defrost by reversal cycle • ΔT decreases by more than 2,5 % after steady state (see the standard EN

14511)

According to the PA declaration this is an unusual/unexpected behaviour of the unit.

Whenever the test at bivalent condition shows a deviation on capacity larger than the allowed acceptance criteria, the Participant will be informed and can choose to stop the test. In this case, a new declaration shall be provided to Eurovent Certita Certification and a new test shall be scheduled.




The complete test shall then be carried out on the repaired unit or a new unit from the same range. The new unit shall be delivered within four weeks from the notification of the failure. If the new unit is not delivered on time it is considered as a non-application of procedures (see Certification Manual).

If the measured capacity at PartLoad condition is not reached, it is considered as an initial test failure. The Participant has to modify (downrate) its declaration.

General

If the value found by testing in the independent laboratory differs more than the acceptance criteria (see APPENDIX A), Participants will have four weeks from the notification of the failure to select one of the following alternatives:

Ask for a second test on the same unit.

Ask for a second test on a new unit. The new unit shall be delivered within four weeks after reply.

Re-rate the same commercial range in accordance with the re-rating rules (see below).

If there is no decision from the Participant after this deadline, the re-rate is applied.

Second test

The paragraph II.2 (especially art.117) of the CM is applicable if the second test is chosen by the manufacturer.

If the second test is performed on the same unit (without any modification on the unit, and not leaving the laboratory), the Participant can choose to repeat only:

• All thermal and pressure measurements or

• All sound measurements

If the second test is performed on a repaired or a new unit, or if the Participant has shipped

back the unit, the complete test shall be carried out.

If the second test is unsuccessful, the Participant shall re-rate according to the results from the second test and the re-rating rules.

The surveillance procedure does not allow for a third test.

The Participant has the possibility to ask a second test composed by all the part loads (including Tbivalent point for air-cooled units) when the seasonal efficiency (ηsc, ηsh and SEPR) is failed.

Re-rating rules

The performance characteristics of the tested model shall be re-rated to the values obtained by testing. If for an application, a test is performed at an additional non-standard condition, the performances (capacity, EER, COP, pressure drop, available pressure) shall be rerated according to the mean deviation between the measurement at standard conditions and the corresponding measurement at the non-standard condition.

Performances at Non Standard conditions shall be justified by a printout from the selection tool of the Applicant/Participant.

It is not acceptable to up-rate claimed values but a voluntary rerating can be possible

The following specific rules shall be applied.




For nominal applications:

1. Capacity fails and EER or COP pass

• The capacity of the tested model shall be re-rated to the values obtained by testing.

• EER (or COP) is not re-rated. • The power input shall be re-calculated from the measured capacity and the

declared EER or COP.

2. Capacity passes and EER or COP fails

• Eurovent Certita Certification shall re-rate EER or COP according to measured values.

• Capacity is not re-rated • Eurovent Certita Certification shall calculate the power input of the tested model

according to the declared capacity and the EER or COP, resulting from measurements

3. Capacity fails and EER or COP fails

• Eurovent Certita Certification shall re-rate EER or COP and capacity according to measured values.

• Eurovent Certita Certification shall calculate the power input according to measured capacity and EER or COP, resulting from measurements

4. Capacity or EER or COP fails

When capacity and/or EER and/or COP fails, the performance characteristics of all other models in the same commercial range as declared by Participant shall be re-rated by the deviation found with the tested model minus 3%.

Example: If the deviation of cooling capacity is – 7 %, the tested model shall be re-rated by – 7 %, and other models in the range by - 4%.

5. Pressure drop or available pressure fails

• The performance characteristic of the tested model only shall be re-rated to the value obtained by testing.

• Other models in the same commercial range are not affected.

6. Sound power level fails

• The performance characteristic of the tested model shall be re-rated to the value obtained by testing.

• The performance characteristic of all other models in the same commercial range shall be re-rated by the deviation found with the tested model minus 2 dB(A) for deviation up to intermediate deviation (intermediate deviation included - see APPENDIX A).

• The performance characteristic of all other models in the same commercial range shall be re-rated by the deviation found with the tested model minus 1 dB(A) for deviation from intermediate deviation (intermediate deviation excluded) to high deviation (high deviation included - see APPENDIX A).

• The performance characteristic of all other models in the same commercial range as declared by Participant shall be re-rated by the deviation found with the tested model for high deviation (high deviation excluded - see APPENDIX A).




For Seasonal applications:

7. Rerating of design load in heating

Whenever the test at bivalent condition shows a deviation on capacity larger than the allowed acceptance criteria, the Participant will be informed and can choose to stop the test (in this case, a new declaration shall be provided to Eurovent Certita Certification and a new test shall be scheduled). Otherwise, the design load is rerated according to the measured deviation for all models in the same basic model group.

8. Part load point fails for SCOP or SEER or SEPR (or ISEER)

When the Participant has tested one part load point, and the COP (respectively EER) is outside the acceptance criteria (see Table 24: Table of acceptance criteria, intermediate and high deviations in Appendix A.I.6), the COP measured (respectively EER) will be applied for SCOP calculation.

Other COP (respectively EER) for part load points will be rerated according with the deviation minus the acceptance criteria used for the test.

When the first Part load (COP) (respectively EER) is outside the acceptance criteria but below or equal to the high deviation, the Participant has the right to ask for a second part load point.

The average deviation will be applied to rerate the other 2 part loads.

If one capacity (lower or upper) stage fails, the Participant can choose to change to the other stage without changing for another part load point.

When the first Part load (COP) (respectively EER) is outside the acceptance criteria but above the high deviation, the Participant has the right to test the 3 other part load points.

9. Rerating of SCOP or SEER or SEPR (or ISEER)

Whenever a measurement at a part-load condition selected by Eurovent Certita Certification shows a deviation on COP (respectively EER) larger than the allowed acceptance criteria, the d.7 or d.8 shall be applied on all the other part load COP (respectively EER) and then, SCOP (respectively SEER or SEPR) and will be recalculated by Eurovent Certita Certification, to be rerated.

Whenever the test on auxiliary power consumption or/and the test on capacity at extreme condition/bivalent condition shows a deviation larger than the allowed acceptance criteria the value of SCOP (respectively SEER or SEPR) should be recalculated.

In case of recalculation of SCOP (respectively SEER or SEPR) for the tested model:

- the deviation on SCOP (respectively SEER or SEPR) shall be applied to all models in the same BMG,

the deviation of the tested auxiliary power consumptions shall be applied to all models in the BMG.Table 14: Example of rerating

BMG Model Items Declared Calculated Deviation Rerated / Calculated Value

1

A SCOP 3,8 3,18 -16% 3,18

B SCOP 3,9 - - SCOPdeclared x (1 - 0,16) 3,26

C SCOP 3,7 - - SCOPdeclared x (1 - 0,16) 3,10

All rerating of SEER or SCOP will lead automatically to the rerating of associated seasonal space efficiency ηsc or ηsh, using the formula mentioned below:




Where:

- CC is the conversion coefficient, equal to 2.5; - ΣF(i) is the correction calculated according to the following formula:

ΣF(i) = F(1) + F(2)

The correction F(1) accounts for a negative contribution due to adjusted contributions of temperature controls, expressed in %. F(1) = 3 %

The correction F(2) accounts for a negative contribution by electricity consumption of ground water chillers / heat pump(s), expressed in %. F(2) = 5 %

10. LRcontmin or CcpLRcontmin fails

EER/COPLRcontmin is measured and compared to the efficiency at LRcontmin derived from the declared CcpLRcontmin.

If the unit allows to keep stable conditions during the test as definied in EN 14511:2018, then LRcontmin is validated.

The values measured are the rerate values.

If the deviation of CcpLRcontmin is within the acceptance criteria, declared CcpLRcontmin is validated.

Otherwise, CcpLRcontmin is rerated according the measured deviation of Ccp.

The performance characteristics of all other models in the same commercial range as declared by Participant shall be re-rated by the deviation found with the tested model or the default values when applicable.

11. Auxiliaries fails: Psb, Pto, Poff, Pck

The tested model shall be re-rated to the values obtained by testing.

The performance characteristics of all other models in the same BMG shall be re-rated by the deviation found with the tested model.

12. TER failed

Eurovent Certita Certification shall re-rate TER according to measured value.

The performance characteristics of all other models in the same commercial range as declared by Participant shall be re-rated by the deviation found with the tested model minus 3%.

The intermediate capacities and efficiencies (EER & COP) will be rerated according to § 1, § 2, § 3 and § 4.

High deviation and penalty tests

For each failure above high deviation in cooling, heating capacity, EER, COP, TER, sound power level, EER at part load condition, COP at part load condition or SCOP, an additional test shall be




scheduled for the next test campaign. There will be a maximum of 3 penalty tests per campaign4. High Failures on several performances in the same test lead to one penalty test.

Liquid Pressure Difference on Outdoor side: Liquid internal pressure difference between outlet and inlet of unit on Outdoor side (kPa).

A-weighed Sound Power Level: Sound power level radiated by the unit (Lw(A)) expressed in dB(A)

The following definitions are in accordance with EN14511-1.

Total Cooling Capacity: Heat given off from the heat transfer medium to the unit per unit time (kW).

Effective Power Input: Average electrical power input of the unit within the defined interval of time (kW) obtained from:

the power input for operation of the compressor(s) and any power input for defrosting

the power input of all control and safety devices of the unit




proportional power input of the conveying devices (e.g. fans, pumps) for ensuring the transport of the heat transfer media inside the unit

Heating Capacity: Heat given off by the unit to the heat transfer medium per unit of time (kW).

Energy Efficiency Ratio (EER): Ratio of the total cooling capacity to the effective power input of the unit (-).

Types of units

2-pipe units

2-pipe units are providing cooling or heating a single water loop.

They can provide cooling only, heating only, can be reversible unit providing seasonal cooling and heating.

2-pipe units + heat recovery

2 pipes + heat recovery (partial or total heat recover) unit are providing cooling and heating at the same time.

They can provide cooling only, cooling + heating, but cannot provide heating if there is no simultaneous demand of cooling (no heating only operation allowed).




This unit are certified only in cooling mode.

4-pipe units

There are two types of 4 pipes units:

1st type is providing cooling and heating to two separate water loops. They can provide cooling only, heating only and simultaneously cooling and heating. One loop always cooling and the other is always heating.

When the units provide cooling and heating at the same time the heating is recovered energy resulting from the cooling operation.

2nd type can provide either cooling or heating on one loop plus only heating on a second loop. Those units are connected to two water loops: one loop is for seasonal comfort cooling and heating, a second loop is dedicated to production of hot sanitary water. When the unit provides cooling on the first loop the heating on the second loop is recovered energy resulting from the cooling operation.

The differences between the “2-pipe units + heat recovery” and the “4-pipe units” are clearly identified specially concerning the number of loop which can be controlled:

For “2-pipe units + heat recovery”, only one loop is controlled (Cooling loop)




For “4-pipe units”, the 2 loops are controlled.

Testing in Participant’s Laboratory

Introduction

All units with cooling capacity at Eurovent Certita Certification Standard Rating Conditions below the limits defined in the relevant Operational Manual shall be tested in an independent laboratory approved and under contract with Eurovent Certita Certification. The choice of the independent laboratory is made by Eurovent Certita Certification.

Units with higher capacity shall be tested either in an independent laboratory or in a Participant laboratory (approved by Eurovent Certita Certification) by an independent agency (selected by Eurovent Certita Certification) following the procedures specified in the APPENDIX A.

The test agency is requested to install its own instruments and to carry out complete test under its own responsibility. The Participant’s personnel are requested to help during the preparation and to operate the test installation during the measurement. The Participant may perform its own measurement in parallel, but only results obtained by the independent test agency are considered by Eurovent Certita Certification.

Basic outline of the procedure

The following procedure shall be applied:

Approval of independent test agencies by Eurovent Certita Certification (based on technical capabilities and cost)

Approval of Participant’s laboratory by the independent agency selected by Eurovent Certita Certification (based on characteristics of test installation)

Selection of unit to be tested by Eurovent Certita Certification

Selection of test agency by Eurovent Certita Certification (based on availability, cost or other considerations)

The Participant provides the selected test agency with all the required information concerning test installation

The test agency notifies the Participant of its requirements to prepare adjustments for installation of measuring probes and instruments

On the agreed date of test, the test agency installs its own instruments and performs the test; the Participant’s staff ensure the correct functioning of the installation

Test report prepared by the test agency is sent to Eurovent Certita Certification

Detailed procedure

13. Approval of Independent Test Agencies

The Independent Test Agency shall have qualified personnel and adequate instruments in order to meet the requirements concerning maximum acceptable uncertainty of measurement as specified in EN 14511-3.

The cooling and heating capacity at the standard rating conditions shall be determined within a maximum acceptance criteria of 5% independent of the individual uncertainties of measurement, including the uncertainties on the properties of fluids.

Concerning the acquisition time period for the output measurement, it is necessary to record all the meaningful data continuously; in the case of recording instruments which operate on




a cyclic basis, the sequence shall be adjusted such that a complete recording is effected at least once every 10 s.

The test agency shall have at least the following equipment:

• Water flow rate (uncertainty + 1%): Electromagnetic flow meter class 0.3 or Ultrasonic flow meter (only intrusion)

• Temperatures (uncertainty: Liquid + 0.1 K, Air + 0.5 K): 12 PT 100 probes with display giving 0.01°C resolution

• Pressure drop (uncertainty + 5%): 2 differential transducers up to 1 bar with display (class 0.5)

• Electrical measurements (uncertainty + 1%): Wattmeter (class 0.5) or Network analyser

• Refrigerant pressure (uncertainty + 1%): Manometer (class 0.5) or Pressure transducers with display (class 0.5)

• Data acquisition system

14. Approval of Participant Laboratory

The Participant shall send an application form to Eurovent Certita Certification. Essential characteristics of test installation shall be indicated. The test installation shall be able to satisfy the requirement of the EN 14511-3 Standard concerning the maximum permissible deviations of measured values from set values.

The test installation shall be designed in such a way that requirement from test agencies concerning installation of measuring probes and instruments be satisfied. That concerns in particular the installation of a water flow meter for which the diameter and length of the connecting pipe are specified. In order to obtain a homogeneous water temperature, a mixing device shall be used on the leaving water.

For the airflow measurement on the ducted units (Indoor and/or outdoor), if a calibration certificate established by an accredited laboratory, of the complete measurement chain of the manufacturer is provided to Eurovent Certita Certification:

o this certificate shall include the following elements in order to be accepted: • for each checking point: manufacturer airflow measurement, test agency airflow

measurement, relative deviation, temperature, relative humidity, inlet absolute pressure, pressure drop across the nozzles measured by the manufacturer6.

• for all checking points the relative deviation between the airflow rate measured by the manufacturer and the airflow rate measured by the test agency shall not exceed 5% after correction by calibration coefficients which is the maximum uncertainty of measurements defined in EN14511-3.

o The manufacturer shall provide to the independent test agency the calibration certificates of all sensors included in the airflow measurement system (temperature, humidity and differential pressure).

In case the test agency determines that the Participant laboratory does not fulfil the required specifications, the test shall not be carried out. The Participant shall then send his unit to the Independent Laboratory for testing.

15. Organisation of test

When the unit to be tested and the test agency have been selected by Eurovent Certita Certification, the direct contact between test agency and Participant shall be established. The test agency shall provide detailed request for preparation to be executed by Participants:

• Connection of water flow meter • Adaptor for temperature probes • Adaptor for pressure transducer

This preparation shall be carried out before the day of the test.

6 For air-cooled units, ducted outdoor, both modes concerned




The test agency and Participant shall agree on the date of test. The test agency personnel shall inspect the test installation and connect measuring devices. The test is then performed under full responsibility of the test agency.

Eurovent Certita Certification shall receive the test report prepared by the test agency.

Rating requirements

General requirements

Tests with brine shall be carried out with the brine composition as specified in the table below.

Table 16: Brine composition

Medium Brine Low Brine

Applications concerned MB, LB

Brine type Ethylene Glycol

Brine composition 30% (weight) 50% (weight)

All tests shall be carried out with clean heat exchangers and that shall be specified in catalogues with published ratings.

For ducted air-cooled chillers tests for capacity shall be carried out at the air flow rate specified as nominal in the published ratings. A unit is considered as ducted if the measured ESP at the declared nominal airflow is higher than 30 Pa.

For units with ducted condenser, ESP must be between 30 Pa and 200 Pa.

Treatment of frosting of heat exchangers

The treatment of frosting shall be done according to EN 14511-3.

Checking of refrigerant

Composition of refrigerant

For 10% of the total number of tests in a test campaign, randomly chosen by Eurovent Certita Certification, a sample of refrigerant is taken just after the end of the test for composition checking.7

Refrigerant charge

The lack of refrigerant is the main reason for failure on cooling capacity. A Participant can choose to send units already equipped with Pressure / Temperature gauges (one for suction, one for liquid, one for discharge). In that case, checking the values by simple reading is part of the unit installation instructions.8

As an option, a Participant can request that the laboratory provide information on suction and discharge pressures and sub-cooling and superheating temperatures. That may help Participants to explain the failure. If the laboratory detects a leak of refrigerant, the test shall be stopped and the leak repaired.

If the Participant requests to check the refrigerant charge before the test, it can be done and the extra cost will be invoiced accordingly. In this case, the laboratory cannot be held responsible in case of failure due to lack of refrigerant.

Capacity Tests

For capacity tests the following Standard Rating Conditions Table 17 and Table 18 shall be used:

Part Load Rating Conditions for SEER (cooling mode for comfort chillers)

For each application, units either allowing or not allowing a variation of the outlet water temperature with the outdoor temperature are considered. The part load conditions for determining the declared capacity and the declared energy efficiency ratio are given in the following table.

The variable outlet temperature (Toutlet_average) shall only be applied when the control provides an outdoor air temperature dependant modification of the outlet temperature.

For units with variable outlet that have to cycle on/off to reach the required part load ratio, the inlet and outlet temperatures of the indoor heat exchanger shall be determined according to formula provided in standard EN14825:2018, paragraph 11.5.1.

Purpose

The purpose of this appendix is to establish definitions and specifications for the operation of the Eurovent Certified Performance (ECP) certification programme for heating-only Hydronic Heat Pumps (LCP-HP).

This standard describes the Appendix A for heating-only Heat Pumps.

Definitions

General definitions

Certified Published Ratings: A statement of the assigned values of those performance characteristics under stated rating conditions, by which a unit may be chosen to fit its application. These values apply to all units of nominal size and type produced by the same Participant.

The term "published rating" includes those shown on the unit, published in specifications, advertising computer selection programmes and other literature controlled by the Company. If the Participant publishes non-certified ratings they shall be clearly indicated.

Standard Ratings: A statement of performance characteristics based on tests performed at standard rating conditions as specified in this appendix A.

Application Ratings: A statement of performance characteristics based on other than standard test conditions.

Basic Model Groups (BMG): The basic models shall be defined by units which are essentially the same in terms of thermal performance (capacities with not more than 10% difference) and function and application. The same or comparable in terms of basic components, specifically fans, coils, compressors and motors. Single-phase and three-phase versions of one model belong to the same BMG.

Hydronic Heat Pump: A factory assembled unit of the self-contained type designed to heat liquid using a compressor, an evaporator and an integral condenser and appropriate controls.

Liquid Pressure Difference on Indoor side: Liquid internal pressure difference between outlet and inlet of unit on Indoor side (kPa).

Liquid Pressure Drop on Outdoor side: Liquid internal pressure difference between outlet and inlet of unit on Outdoor side (kPa).

A-weighed Sound Power Level: Sound power level radiated by the air source heat-pump (Lw(A)) expressed in dB(A)

The following definitions are in accordance with EN 14511-1:2018




Effective Power Input: Average electrical power input of the unit within the defined interval of time (kW) obtained from:

the power input for operation of the compressor(s) and any power input for defrosting

the power input of all control and safety devices of the unit,

proportional power input of the conveying devices (e.g. fans, pumps) for ensuring the transport of the heat transfer media inside the unit

Heating Capacity: Heat given off by the unit to the heat transfer medium per unit of time (kW)

Coefficient of Performance (COP): Ratio of the heating capacity to the effective power input of the unit (-).

Power input in stand-by mode (Psb), in off mode (Poff), in thermostat-off mode (Pto), in crankcase heater modes (Pck): as defined in EN 14825: 2018.

LRcontminh: Load rate under which a unit with a variable speed compressor behaves as an ON/OFF unit. For staged capacity units it is the load rate of the smallest capacity step in full mode. For ON/OFF units LRcontmin equals 1.

CcpLRcontminh: Ratio of the COP at LRcontmin and the COP at Low temperature application (previously Heating floor application).

Energy Classification

Classification concerns COP at the rating conditions.

The energy efficiency of heat-pumps is designated by “Eurovent Certita Certification Class …” in catalogues and in the present ECP Website of Certified products. The following limits between classes have been defined.

Testing requirements

Testing in Participant’s Laboratory

Introduction

All units with heating capacity at Eurovent Certita Certification Standard Rating Conditions below the limits defined in the relevant Operational Manual shall be tested in an independent laboratory approved and under contract with Eurovent Certita Certification. The choice of the independent laboratory is made by Eurovent Certita Certification.

Units with higher capacity shall be tested either in an independent laboratory or in a Participant laboratory (approved by Eurovent Certita Certification) by an independent agency (selected by Eurovent Certita Certification) following the procedures specified in the APPENDIX A.

The test agency is requested to install its own instruments and to carry out the complete test under its own responsibility. The Participant’s personnel are requested to help during the preparation and to operate the test installation during the measurement. The Participant may perform its own measurement in parallel, but only results obtained by the independent test agency are considered by Eurovent Certita Certification.

Basic outline of the procedure

The following procedure shall be applied:

Approval of independent test agencies by Eurovent Certita Certification (based on technical capabilities and cost)

Approval of Participant’s laboratory by the independent agency selected by Eurovent Certita Certification (based on characteristics of test installation)

Selection of unit to be tested by Eurovent Certita Certification

Selection of test agency by Eurovent Certita Certification (based on availability, cost or other considerations)

The Participant provides the selected test agency with all the required information concerning test installation




The test agency notifies the Participant of its requirements to prepare adjustments for installation of measuring probes and instruments

On the agreed date of test, the test agency installs its own instruments and performs the test; the Participant’s staff ensure the correct functioning of the installation

Test report prepared by the test agency is sent to Eurovent Certita Certification

Detailed procedure

Approval of Independent Test Agencies

The Independent Test Agency shall have qualified personnel and adequate instruments in order to meet the requirements concerning maximum acceptable uncertainty of measurement as specified in EN 14511-3.

The capacity at standard rating condition shall be determined within a maximum acceptance criteria of 5% independent of the individual uncertainties of measurement, including the uncertainties on the properties of fluids.

Concerning the acquisition time period for the output measurement, it is necessary to record all the meaningful data continuously; in the case of recording instruments which operate on a cyclic basis, the sequence shall be adjusted such that a complete recording is effected at least once every 10 s.

The test agency shall have at least the following equipment:

• Water flow rate (uncertainty + 1%): Electromagnetic flow meter class 0.3 or Ultrasonic flow meter (only intrusion)

• Temperatures (uncertainty: Liquid + 0.1 K, Air + 0.5 K): PT 100 probes with display giving 0.01°C resolution

• Pressure drop (uncertainty + 5%): 2 differential transducers up to 1 bar with display (class 0.5)

• Electrical measurements (uncertainty + 1%): Wattmeter (class 0.5) or Network analyser

• Refrigerant pressure (uncertainty + 1%): Manometer (class 0.5) or Pressure transducers with display (class 0.5)

• Data acquisition system

Approval of Participant Laboratory

The Participant shall send an application form to Eurovent Certita Certification. Essential characteristics of test installation shall be indicated. The test installation shall be able to satisfy the requirement of the EN 14511-3 Standard concerning the maximum permissible deviations of measured values from set values

The test installation shall be designed in such a way that requirement from test agencies concerning installation of measuring probes and instruments could be satisfied. That concerns in particular the installation of a water flow meter for which the diameter and length of the connecting pipe are specified. In order to obtain a homogeneous water temperature, a mixing device shall be used on the leaving water.

For the ducted units (indoor and/or outdoor), if a calibration certificate, etablished by an accredited laboratory, of the complete measurement chain of the manufacturer is provided to Eurovent Certita Certification:

• this certificate shall include the following elements in order to be accepted:

- for each checking point: manufacturer airflow measurement, test agency airflow measurement, relative deviation, temperature, relative humidity, pressure drop across the nozzles measured by the manufacturer10.

- for all checking points the relative deviation between the airflow rate measured by the manufacturer and the airflow rate measured by the test

10 For air-cooled units, ducted outdoor




agency shall not exceed 5% after correction by calibration coefficients which is the maximum uncertainty of measurements defined in EN14511-3.

• The manufacturer shall provide to the independent test agency the calibration certificates of all sensors included in the airflow measurement system (temperature, humidity and differential pressure).

In case the test agency determines that the Participant laboratory does not fulfil the required specifications, the test shall not be carried out. The Participant shall then send his unit to the Independent Laboratory for testing.

Organisation of test

When the unit to be tested and the test agency have been selected by Eurovent Certita Certification, the direct contact between test agency and Participant shall be established. The test agency shall provide detailed request for preparation to be executed by Participants:

• Connection of water flow meter • Adaptor for temperature probes • Adaptor for pressure transducer

This preparation shall be carried out before the day of the test.

The test agency and Participant shall agree on the date of test. The test agency personnel shall inspect the test installation and connect measuring devices. The test is then performed under full responsibility of the test agency.

Eurovent Certita Certification shall receive the test report prepared by the test agency.

Rating requirements


All tests shall be carried out with clean heat exchangers and that shall be specified in catalogues with published ratings.

For ducted air-source heat-pumps, tests for capacity shall be carried out at the air flow rate specified as nominal in the published ratings. A unit is considered as ducted if the measured ESP at the declared nominal airflow is higher than 30 Pa.

Treatment of heat exchangers frosting

The treatment of frosting shall be done according to EN 14511:2018.

Checking of refrigerant

Composition of refrigerant

For 10% of the total number of tests in a test campaign, randomly chosen by Eurovent Certita Certification, a sample of refrigerant is taken just after the end of the test for composition checking.11

Refrigerant charge

The lack of refrigerant is a principal reason of failure on capacity. A Participant can choose to send units already equipped with Pressure / Temperature gauges (one for suction, one for liquid, one for

11 See minutes of meeting held on 25/04/2004




discharge). In that case, checking of the values by simple reading is part of the instructions of installation of the unit.12

As an option, a Participant can request that the laboratory provide information on suction and discharge pressures and sub-cooling and superheating temperatures. That may help Participants to explain the failure. If the laboratory detects a leak of refrigerant, the test shall be stopped and the leak repaired.

If the Participant requests to check the refrigerant charge before the test, it can be done and the extra cost will be invoiced accordingly. In this case, the laboratory cannot be held responsible in case of failure due to lack of refrigerant.

Capacity Tests

For capacity tests the following Standard Rating Conditions Table 25 shall be used:

One global value will be considered. The following certified performances are taken into account:

cooling capacity at full load (Pc)

heating capacity at full load (Ph)

EER at full load

COP at full load

Sound levels

And depending on the choice of the manufacturer; either:

EER at part load if one or two tests are performed on the unit, or

The thresholds to consider are the intermediate deviations given in Table 24 (A.I.6) and Table 26 (A.II.6).

Eurovent Certita Certification takes into consideration data of the last three test campaigns of each manufacturer.

A manufacturer is suspended from the Eurovent Certita Certification Programme for one year if the mean value of failure MVF is higher than 25%.

A Participant who is going to be suspended will receive a notification from Eurovent Certita Certification, with a possible additional selected unit to be tested. The purpose of this additional test is to give the Participant the opportunity to comply with the limits. The response to Eurovent Certita Certification with confirmation of request for additional testing has to be done within 30 days after this notification, and the unit has to be delivered within 45 days after this notification.
