PURPOSE The purpose of this manual is to prescribe procedures for the operation of the Eurovent Certified Performance Programme for Air Handling Units, in accordance with the Eurovent Certified Performance Certification Manual. II. SCOPE This programme applies to selected ranges of Air Handling Units. Each range shall at least present one size with a rated air volume flow below 7 m 3/s. All Real Unit sizes in the range up to the maximum stated air flow shall be declared. All Model Box configurations shall be declared. Ranges without at least one size with a rated air volume flow below 7 m 3/s (25 000 m3/h) are excluded. III. BASIC OUTLINE OF THE PROGRAMME III.1 Preapplication Before the licence agreement is signed between the company and Eurovent Certita Certification, the preapplication procedure shall be completed. The company shall first submit to Eurovent Certita Certification name of the range and complete list of names and versions of the corresponding selection tools (selection softwares) for verification by an auditor appointed by Eurovent Certita Certification. If the software fulfils all preliminary requirements, the company shall submit to Eurovent Certita Certification the complete list of factories where the range is produced for verification by an auditor appointed by Eurovent Certita Certification. If the software and the factory fulfil all the preliminary requirements, the company is entitled to sign the Licence Agreement. III.2 Qualifying procedure After signing the Licence Agreement, the Applicant shall submit to Eurovent Certita Certification the declaration list with all Real Unit (RU) sizes and Model Box (MB) configurations with all the required characteristics and performance data as required by the Rating Standard, RS 6/C/005. The following number of units per factory producing the range (except the case of “sister factories”, see IV.10) are then required for test in an independent laboratory selected by Eurovent Certita Certification: The minimum number of Model Boxes to cover all worst configurations of the mechanical, thermal and acoustical performance. If several ranges use the same construction, the corresponding unit will be tested only once. One complete Air Handing Unit, being one size from the range, for all performance. The Real Unit is selected during the factory visit by the auditor appointed by Eurovent Certita Certification. For units above the stated air flow rate of 7 m3/s, the software shall be checked for consistency. If the tests show conformity with the relevant Rating Standard and consistency is verified, certification is granted until next annual on-site checking of software. III.3 Repetition procedure For mechanical, thermal and acoustical testing, Model Boxes shall be tested every six years for ISO-certified factories, every three years otherwise. For performance testing, a Real Unit from recent regular production shall be tested, every three years for ISO-certified factories, AHU, OM-5-2014 Published February 2014 Page 5 of 36 every year otherwise. If several factories produce exactly the same range with the same components, suppliers and methods, one unit is sufficient instead of one per factory. In addition, annual onsite checking of software shall be carried out every year. When the repetition procedure is passed certification is renewed for another campaign. III.4 Failure treatment When a unit fails to comply with the requirements of the relevant Rating Standard, failure treatment shall be applied. IV. OPERATION OF THE PROGRAMME IV.1 Declaration of data Each manufacturer shall nominate one contact person who will deal with all certification matters, plus eventually one by factory. a. Rated performance data All characteristics shall be expressed in SI Units. b. Certification forms Submittal of certification of models shall be completed and sent to Eurovent Certita Certification as .xlsx files. Copies of these forms are part of this manual (see APPENDIX D). Original Equipment Manufacturer (OEM): Form AHU-1A for Real Units and Form AHU-1B for Model Boxes will be used. Brand Name: For models submitted by a company presenting on the market units, under its own brand, manufactured by a certified company, forms AHU-2A and AHU-2B will be used to identify the corresponding model number of the OEM. Technical forms: For models selected for test, Forms AHU-3A and AHU-3B have to be completed with technical description of all components along with characteristics and performance data. Evaluation of test result: For models tested, Forms AHU-4A is added to the test report and AHU-4B is sent by Eurovent Certita Certification, showing the deviations between claimed and measured data. c. Modifications to the range The Participant shall inform Eurovent Certita Certification and the auditor of any modification to the range and/or software, using Form AHU-5. A new software version without impact on performance does not have to be sent. If new components (fans, coils etc) are implemented in standard production, manufacturer shall inform Eurovent Certita Certification and provide new software to the auditor. For next test new components shall be selected. Non compliance is considered as a non-respect of procedures (see IV.14). Anytime, Eurovent Certita Certification has the right to perform extra checking of software. Eurovent Certita Certification decides whether the modification is significant for the certified performance data or not. In the case of significant modifications Eurovent Certita Certification is entitled to demand adequate tests to verify the influence on performance data. This test shall not be considered as a repetition one. AHU, OM-5-2014 Published February 2014 Page 6 of 36 IV.2 Preapplication procedure During the preapplication procedure, the auditor appointed by Eurovent Certita Certification shall first verify that the software fulfils minimum requirements (no certification shall be accepted without appropriate selection software). If yes, he shall visit the factory, verify that AHUs are really manufactured there and selected with the software, and send a report of his visit to Eurovent Certita Certification. If the report shows that rules are not followed the Licence Agreement shall not be signed. IV.3 Software An English version of the software selection is necessary. Each quotation of a certified AHU shall include the date/code/number of the software version used for the selection of the unit. From the version code-key it shall be possible to check what the latest technical software version is by splitting up the code in more characters. An example of a suitable code is given below: Version: XY / Z characters indicating a version serial number, not affecting the selection results characters to indicate the technical version serial number The participant is obliged to send the most recent technical software version to Eurovent Certita Certification. The selection software shall be operative as an entity with all unit components integrated in one software. Components in an AHU that are selected with different software or any other means of selection cannot be certified. The units of the applied range shall be built with components specified in the selection software. If some components not present in the certified software performing a certified performance item (see VI.2 of Rating Standard) are included in the technical specification of a particular order, the following statement shall be provided in the quotation: “This component is not included in the software Eurovent certified”. This statement is not required for components serving for non-certified performance items (see list on VI.2 of RS 6/C/005). At least four sections must be included: fan, filter, heating and cooling. When a heat recovery section is available, it shall be declared and included in the selected unit for test for certification. Consistency of the software shall be verified by the auditor appointed by Eurovent Certita Certification. In case inconsistency of the software is observed, failure treatment shall be applied. Anytime, Eurovent Certita Certification has the right to collect data directly from customer and perform extra checking of software. IV.4 Factory visits Before each visit the auditor appointed by Eurovent Certita Certification shall collect and study the construction details and claimed performance of the relevant AHU range in order to make a proper selection of suitable unit(s) for testing. Anytime, Eurovent Certita Certification has the right to ask an auditor to conduct a surprise visit to participants’ factory as well as to collect data directly from customer and perform extra checking of software. During selection visits, a factory tour shall be made by the auditor, accompanied by manufacturer’s technical expert. A random selection of at least one unit under construction or just built, shall be made. The selected unit shall be suitable for testing. If no unit suitable for AHU, OM-5-2014 Published February 2014 Page 7 of 36 testing is under construction or just built, a random selection from files of recently delivered units shall be made. The entire composition and technical specifications of the selected units shall then be checked onsite. Manufacturer’s technical expert shall fully inform the auditor by submitting all relevant assembly drawings, specifications and technical data sheets of the selected units. Agreement shall be reached between manufacturer and the auditor on final selection of Real Unit for testing. During annual on-site checking of software, the same procedure shall be applied, without selection of unit for testing so without the restrictions for measuring facilities. This implies that any size may be selected. The expected performance shall be recalculated based on components reselected with the software provided to Eurovent Certita Certification. The composition and technical specifications and performance from recalculation shall be the same as the one specified and announced to the customer. If in the meantime the Participant has officially launched a new software version and recalculation is made with this version, deviations should be traceable in the software update record sheet (see D.IV.2). Deviations on performance above tolerances can lead to additional test (see IV.1c). If it appears that different software had been used, this shall be considered as a non-respect of procedures (see Certification Manual). In addition, mechanical construction (all the parameters) of one production unit shall be verified by the auditor, to compare certified characteristics of production with the tested Model Box(es). If it appears that different construction had been used, additional Model Box test shall be required by the auditor. Finally, consistency of heat recovery shall be verified by the auditor. At least one unit shall be verified with the methodology detailed in the following paragraph. In case of force majeure (e.g. accidents, labour disputes, natural events, acts of war) which would not allow Eurovent Certita Certification to perform a factory visit Eurovent Certita Certification can decide to replace it by another mean of verification, to postpone it within a reasonable deadline or to cancel it. The Compliance Committee will be made informed regarding these cases. IV.5 Consistency check of heat recovery a. Manufacturer uses Eurovent certified heat recovery systems (HRS) Compare the efficiency and pressure drop data in the AHU quotation or software with results obtained from the current stand-alone certified software from the HRS supplier. AHU manufacturer can never claim higher efficiencies and/or lower pressure drops than the values received from the stand-alone software. If possible one quotation with a rotor and one quotation with a plate heat exchangers have to be checked. b. Manufacturer does not use Eurovent certified HRS Additional testing of non-certified HRS are requested in the laboratory of the regular certification campaign, of the different models, one every year. Repetition would only be necessary in case of change of the structure of the HRS. When a HRS is tested in the RU one year, this additional testing is not necessary for that year. Compare the efficiency and pressure drop data in the AHU quotation or software with results obtained from the test result. Deviation shall be equal or lower than the acceptable tolerance defined in the certification programme for the HRS. In case a RU is tested every year, this additional testing is not necessary. AHU, OM-5-2014 Published February 2014 Page 8 of 36 c. For certified and non-certified rotors Observations of rotor arrangements in the AHUs shall be made during the annual factory inspection. If it appears that (sometimes) parts of the actual heat exchanger surface of the rotor are blanked / obstructed it shall be verified in manufacturer’s software if this unfavourable assembly has been considered. The software shall predict (small) reduction in efficiency and (substantial) pressure drop increase, compared to a selection with completely open rotor surface. IV.6 Qualifying campaign For a company (“Brand name”) presenting on the market units, under its own brand, manufactured by a certified company, only on-site checking of software shall be conducted at the place (“office”) where the orders to the customers can be accessed. This place is often the factory of the certified manufacturer. For manufacturers, Real Units taken from the production line shall be selected by the auditor appointed by Eurovent Certita Certification during a factory visit, using the selection software. Models Boxes will be directly selected by Eurovent Certita Certification from the declaration list, to cover all worst configurations of the mechanical, thermal and acoustical performance (see Table 1). Selected units shall be sent to the independent laboratory within maximum 6 months. If this deadline is not fulfilled another on-site checking with selection shall be scheduled within maximum one year from the previous on-site checking. Units are then tested and the obtained performances compared with the values calculated using the software. The test on the Real Unit of a range can be carried out after the test results on the Model Box(es) is/are available. Assembly places of flat-package units shall be considered exactly the same way as manufacturing places. When a manufacturer presents several manufacturing places, each place shall be considered independently. If all the test results are within the tolerances and calculation model appears consistent, Eurovent Certita Certification shall grant the certification. If not, failure treatment shall be applied. When certified, the range is published on the Eurovent Certified Performance website with an agreement number, associated characteristics and performance, name and version of the last software verified by Eurovent Certita Certification, and production places. The participant is then entitled to use the certification mark for this range in literature and on products (see V.2). It shall be obvious for which products the certification is granted (see also APPENDIX B and Certification Manual). IV.7 Repetition campaign For a company (“Brand name”) presenting on the market units, under its own brand, manufactured by a certified company, only on-site checking of software shall be conducted annually at the place (“office”) where the orders to the customers can be accessed. For manufacturers, Participant’s quality control shall be appropriate to maintain the performance within the tolerances. A quality system according to ISO 9001 (covering the production quality systems) is acknowledged by a reduction in the frequency of repetition tests. The manufacturer shall then annually provide a valid ISO 9001 certificate to Eurovent Certita Certification. In addition, annual on-site checking shall be performed in each Participant’s factory(ies). Assembly places of flat-package units shall be considered exactly the same way as manufacturing places. AHU, OM-5-2014 Published February 2014 Page 9 of 36 For each certified range and factory, repetition tests in the independent laboratory selected by Eurovent Certita Certification shall be required: Every six years for mechanical, thermal and acoustical performance on Model Boxes for participants holding valid ISO 9001 (every three years otherwise) Every three years for performance on Real Unit for participants holding valid ISO 9001 (every year otherwise) Eurovent Certita Certification shall select the units for repetition using the same procedure as for selection of units for the qualification test. If possible, a RU size or MB configuration different from those previously tested shall be selected. If all the test results are within the tolerances and calculation model appears consistent, Eurovent Certita Certification shall maintain the certification for another period. If not, failure treatment shall be applied. IV.8 Ranges to be taken out of production Running a test on a unit from a range which is going to disappear from the market can represent a useless cost for the Participants. If a test is necessary on a unit from a range which is going to disappear from the market, the Participant may send an official letter to Eurovent Certita Certification stating that the range will disappear between the date of the scheduled test and the date + one year. The range remains then certified for maximum one year. If the Participant changes his mind or if it appears that the range is still available after that time, it is considered as a major breach of the rules, and the Participant will have to pay a penalty fee of 15 000 €. In addition, the unit will have to be tested and the following test will have to follow normal schedule. IV.9 Selection of units for tests Table 1: Table for selection of model boxes Construction variation Corner post Mullion Filter construction Panel shape Panel thickness Sheet metal thickness Insulation material (wool vs foam): - density out of - 25% - conductivity out of + 15% Way of insulation mounting (fixed vs loose) Metal sheet of panel (galvanized vs stainless steel) Casing strength x x Casing air leakage x x x the thinnest the thinnest x the thinnest x (density) Filter bypass Thermal leakage transmittance x x x x x x the thinnest the thickest - Thermal bridging x x Acoustic insulation x x x the thinnest the thickest x the thinnest the thinnest x x (conductivity) (conductivity) x x (density) x worst case: galvanized worst case: galvanized External finishing (galvanized vs coated) Hinge and /or latch Regarding Model Boxes, Eurovent Certita Certification shall select the minimum number of units to cover the construction variations available on the software and catalogue under the declared range names. All variations (marked by a X) and worst cases are mandatory to be tested according to the Table 1 above, and worst case performances can be transferred from the tested MB to other constructions. To claim better class on one performance data, another MB with the construction parameter variation has to be tested too. AHU, OM-5-2014 Published February 2014 Page 10 of 36 Selection of one Real Unit suitable for testing shall be made during selection visits as described above (see IV.4). Size of the units, air volume performance, heating and cooling capacity, shall be within the limits of the measuring facilities of the laboratory. An up-scaled or down-scaled unit can be selected if no suitable size is available. In case no unit with heat recovery or cooling/heating coils can be provided by the factory, these components and the associated performance shall be non-certified. Because it is a significant parameter for the energy efficiency classification, in case the software proposes heat recovery, then the selected unit shall include heat recovery. Unit for test shall be supplied to the laboratory within six weeks for factories in Europe and within eight weeks for factories outside Europe (see APPENDIX C). When the manufacturer does not meet the time limits for the supply of units this will be considered as a non-respect of procedures. The manufacturer shall inform the laboratory (preferably before the test) if he wants the unit to be scrapped after the test results are available. IV.10 Ranges produced in several production places When a manufacturer presents several production places, each place will be considered independently so each factory has to be visited every year by the auditor appointed by Eurovent Certita Certification (selection or annual on-site checking). Assembly places of flatpackage units shall be considered exactly the same way as manufacturing places. Regarding the selection of units to be tested, the production places for an identical product – identical software, identical components (designation) and suppliers, same casing (same drawings and materials), same assembly procedures and ISO 9001 – have to be considered as one collective production place. In that case each time a different production location will be randomly chosen for the selection of the unit to be tested. The different production places are thus called “sister production places”. During the annual on-site checking (see IV.4), if there is any suspicion that the production place cannot ensure the same performances as its sister production places, then the auditor may ask that a Real Unit and/or Model Box be tested. IV.11 Procedures at the laboratory a. General Only the independent laboratory personnel shall be permitted to handle test units. The manufacturer's installation and handling instructions shall be followed. The laboratory shall be responsible for uncrating, handling, testing and recrating the unit for shipment. The laboratory personnel shall make repairs to the test unit only in agreement with the manufacturer. No manufacturer's personnel shall be present in the test facility during the test. b. Test conditions The units shall be tested at the conditions as stated in the relevant Rating Standard. Thermal tests will be performed at 2 conditions in the heating mode and 2 conditions in the cooling mode (one condition at manufacturer’s rated design and one condition selected by Eurovent Certita Certification within the scope of the selection software). Independent laboratory shall test units at the conditions as close as possible to the selected rating conditions. Aerodynamic tests (air flow - pressure - power input) shall be performed in accordance with the test standard ISO 5801, in an operating range of +/-5% around the selected rating point. AHU, OM-5-2014 Published February 2014 Page 11 of 36 Testing for heat recovery shall be carried out with at least 20 K difference, under dry conditions (supply air temperature should not be below +5°C). c. Test report and tests results For each unit, upon completion of all the measurements, the laboratory will render a test report (pdf) to Eurovent Certita Certification with tested data compared to original selection data. If at least one performance measurement is out of the tolerances, the auditor shall conduct a “test check”, i.e. the selection software will be used to recalculate the performance at conditions used for test: test data will be compared to recalculation data. Eurovent Certita Certification will transmit a copy of the report together with results of test check (Forms AHU-4, see APPENDIX D). Manufacturer has to collect its products one month after receiving the test report. After this delay, the laboratory will destroy the units if not collected and the manufacturer will be invoiced through Eurovent Certita Certification. If the results are out of the allowable tolerance, or the calculation model appears inconsistent, failure treatment shall be applied. IV.12 Failure treatment For each test, a performance item fails when the difference between the declared value and the measurement differs by more than the allowable tolerance (see relevant Rating Standard). A test fails when one or more performance(s) fail. In case of failure, Eurovent Certita Certification shall promptly notify the Participant. a. Component failure The manufacturer shall be authorised to examine the reasons of the failure. In case of a component failure the unit may be repaired or replaced by a new one of the same model within 4 weeks, which shall be tested then, according to normal schedule of the laboratory. b. Unit failure on a real unit If the failure is established after the recalculation, the manufacturer shall rerate his data by adapting the software to the test results within 6 weeks (see APPENDIX C). If the software is then in accordance with all measurements, certification is granted or maintained with the re-rated data. After reverification (“test recheck”), if the software is still not in accordance with the test results, manufacturer will have two additional weeks for final adjustment of the software (see APPENDIX C). In case of new failure, no adjustment of software will be accepted and manufacturer has to restart the test procedure. c. No class reached during RU tests In case of failure on RU tests not reaching any Filter By-pass Leakage (FBL) class, it is considered as Component failure (immediate stop of the test) and complete retest is mandatory. In case retest is failed, manufacturer is excluded from the programme for 1 year. In case of failure on RU tests not reaching any Casing Air Leakage (CAL) class, it is considered as Component failure (immediate stop of the test) and complete retest is mandatory. In case retest is failed, manufacturer is excluded from the programme for 1 year. AHU, OM-5-2014 Published February 2014 Page 12 of 36 d. Unit failure on a Model Box Manufacturer has four weeks after notification of failure to select one of the following alternatives: Accept measured values. (Uprate is allowed.) Ask for a second test on the same unit. In this case, the Manufacturer can choose to re-test only the performances which are not accepted Ask for a second test on another unit of the same model selected by Eurovent Certita Certification. The delivery shall be done within 8 weeks from the date of the test report. In this case, all measurements are to be re-tested. e. Failure in case of multiple production places When a range is tested for different production places, if one repetition test fails, all production places will have to re-rate their data and the software shall be re-rated according to the worst test results for each performance item. f. Irregularities in production places Irregularities found in a factory can be a reason for retesting or suspension of certification of the factory or the complete range. In case several factories produce the same range, if one factory is suspended, the Participant has one year to align it. After this delay, if the factory is still not in accordance with the requirements, the complete range is suspended from certification for one year. IV.13 Special complaint procedure The general complaint procedure is described in Certification Manual. In addition, if a Participant obtains doubtful data from a competitor quotation he may present a complaint request. The Participant who complains will pay 1000 € as fee. Eurovent Certita Certification auditor will examine complaint within 6 weeks and complaint data will be also used during annual on-site checking. If checking results show that the obtained data are different – meaning that other software had been used or quotation data manipulated – this is considered as a non-respect of procedures (see Certification Manual). The 1000 € fee will then be sent back to the plaintiff and it will be invoiced to the Participant who failed. IV.14 Brand Name This covers the case of models submitted by a company presenting on the market units, under its own brand, manufactured by a certified company. When Company A doesn’t produce his own range but distributes under its own brand ranges already certified by Participant B, no additional test is required for A. Nevertheless, A has to declare to Eurovent Certita Certification a place (“office”) where the orders to the customers can be accessed to and the software can be annually verified by an Eurovent Certita Certification auditor, during the same quarter as the verification of software hold by B. A’s office is often B’s factory. If a range or a production place of B doesn’t fulfil the requirements and B’s certificate is suspended and/or expelled from the programme, A is also automatically suspended. If B quits certification, A is offered the possibility to cover test expenses for B’s products. The Brand of the A company must be shown on the output. A is fully responsible of his software and any non compliance may have a consequence on A certification, even if B is the software provider.
