2 Liquid to liquid Plate Heat Exchangers certification 17 October 2018 Nuremberg Marie-Clémence BRIFFAUD Project Development Manager

3 Agenda of the presentation 1. Presentation of Eurovent Certita Certification 2. How does a certification programme work? 3. Overview of the LPHE certification programme

4 Where is the added value of voluntary third party certification? My product is the best My product is the best My product is the best My product is the best

5 Where is the added value of voluntary third party certification? Third-party certification establishes rules that enable an objective assessment of the performances COMMON AND FAIR RULES common evaluation criteria integrity + impartiality fairness of the ratings precision and transparency of data. AN OBJECTIVE COMPARISON Certified characteristics published on Eurovent Certita Certification website

6 What are the guarantees????????????? Integrity* Independency* Impartiality* Competency* * ISO Accreditation by COFRAC (n ) recognized by agreements EA/IAF : and

7 The voluntary certification marks delivered by ECC

8 The Eurovent Certified Performance mark (1/2) Some brands never mislead 25 manufacturers disqualified 1600 tests in laboratory Tests last between 2 and 5 days >200 software checks 400 audits Performance reports available on Internet 24/7 Data of 2015

9 The Eurovent Certified Performance mark (2/2) VENTILATION & INDOOR AIR QUALITY Air Handling Units (+ higienic option) Ventilation ducts Air Filters Residential Air Filters INDOOR CLIMATE Variable refrigerant flow Liquid-to-liquid plate heat exchangers Fans Air Cleaners Air to air heat exchangers Residential AHU Rooftops Chilled beams Air conditioners Fan coils PROCESS COOLING & FOOD COLD CHAIN Refrigerated Display Cabinets Drift eliminators Chillers & Heat-Pumps Evaporative cooling Heating & Cooling Coils Heat Recovery Systems with intermediate heat transfer medium Cooling towers Heat Exchangers for refrigeration

10 How does a certification programme work? Decision of certification Test results OK Audit OK Software check OK Certificate delivered (or renewed) Certification manual + Operational manual + Rating Standard

11 Overview of the LPHE certification programme 3 product types : Gasketed plate-and-frame heat exchangers Brazed plate heat exchangers Fusion-bonded plate heat exchangers SCOPE Several fluids : Clean water (and by extension seawater) Aqueous solutions (EG, PG, EA) Liquid-to-liquid PHE used in HVAC applications (but not refrigeration)

12 Overview of the LPHE certification programme Range = family of plate heat exchangers models of the same product type (gasketed or brazed or fusionbonded) named under a unique designation. Model* = family of references which present the same essential characteristics (plate-to-plate pitch; nominal plate dimensions; distances between port axis; pattern type; single-wall/double-wall) Note : Certify-all applicability to be reconsidered in 2023 CERTIFICATION BY RANGE 1 Certificate per range *vocabulary used on the LPHE market

13 Overview of the LPHE certification programme Measured parameters Pressure drop on primary 1 circuit [kpa] Pressure drop on secondary 2 circuit [kpa] Calculated parameter Capacity [W] CERTIFIED CHARACTERISTICS 1 Primary fluid (EN 306:1997) : Fluid acting as the heat source (t 11 >t 12 ) 2 Secondary fluid (EN 306:1997) : Fluid acting as the heat sink (t 21 <t 22 )

14 Overview of the LPHE certification programme TEST Conducted by an independent laboratory ISO accredited Specific test method in Rating Standard notably based on, but amending, standards EN 306:1997 and EN 1148:1999 list of test conditions defined (temperatures + possible fluids) 1 condition tested (design condition only) Test location Independent laboratory facility by default Participant laboratory (upon request) for big units (H > 2,5 m) and/or heavy units (> 3 tons) and/or nonscalable units* see Operational manual & Rating Standard *as last resort the test report can be provided by the participant

15 Overview of the LPHE certification programme Scaling down procedure Enables to reduce the number of plates and therefore The flow rate The capacity different Plate size remains the same see Operational manual same

16 Overview of the LPHE certification programme Selection of models to be tested 1. Selection of models to be tested in the declaration file 1/4 of the models with at least 4 models selected in qualification procedure (entry year) 1/10 of the models with at least 2 models selected in repetition procedure (subsequent years) If more than three (3) new models are introduced in the range during the annual declaration file update (LPHE-1 file) then one (1) extra test will be conducted on one (1) of this new models 2. Software running to get the product design details and the performances for a given operating condition 3. The list of selected designs is sent to the applicant/participant to order the manufacturing see Operational manual

17 Overview of the LPHE certification programme AUDIT 1 audit / factory / year Onsite inspection of products to be tested Verification of declaration file consistency Verification that key controls are conducted and recorded Plate pressing checks : Visual check at a given frequency Pressing depth check at a given frequency Pressure and leak testing see Operational manual

18 Overview of the LPHE certification programme 1. Pre-check (remote) Verification of compliance to general and specific requirements E.g. : Printout content 2. On-site check (audit) Verification that the software version submitted for certification is the one used in situ Verification that all orders are treated fairly (no undersizing, etc.) 3. Software / test results comparison ( Test check ) Verification of consistence between software ratings and test results CHECK SOFTWARE see Certification Manual and Operational manual

19 Overview of the LPHE certification programme Wide and clear scope Definition of model without any possibility of ambiguity Covers aqueous solutions (EG, PG, EA) Robustness Annual checks (tests + audit(s) + software checking) Penalty tests foreseen in case of established failure Possibility for any end-user to ask for a printout check STRENGHTS
