EUROVENT KÄLTE KOLLOQUIUM: Ninth presentation
"Testing and certification of refrigeration systems and refrigeration components."
This presentation by TÜV SÜD Industrie Service GmbH explains the purpose of certification and the role it plays in the food cold chain. The presentation explores the laboratory tests undertaken at TÜV SÜD as part of the Eurovent Certified Performance certification process for evaporators, before discussing the testing of a range of refrigeration equipment for buildings and transport.
About the EUROVENT KÄLTE KOLLOQUIUM
Over two days, from 4th - 5th June 2024, operators, planners and manufacturers explored reliable refrigeration systems for the cold chain, "From Farm to Supermarket," in Wiesbaden, Germany. A comprehensive technical programme took delegates from theory to practical, with a mix of seminars and excursions, perfectly blended to encourage learning, discussion and networking in inspiring surroundings.
Organised by Eurovent Certification and COOLPLAN, with media partners CCI and KKA, day-one was hosted at the historic Kloster Eberbach. The extensive technical programme scrutinised the latest trends in refrigeration, decarbonisation and boldly tackled issues such as underperformance and its impact on food quality and energy efficiency.
Day-two put the theory into practice, with the chance to go explore cold food chain technology in its natural habitat, with excursions to a green farming market and NH3/CO2 logistics warehouse.
The presentation
"Testing and certification of refrigeration systems and refrigeration components."
The ninth and final lecture of day-one was from Peter Schnepf, Head of refrigeration laboratory at TÜV SÜD Industrie Service GmbH. Peter launched straight into the purpose of certification, defining the role it plays in the food cold chain.
Using the certification example for an evaporator, Peter explained the laboratory tests undertaken at TÜV SÜD as part of the Eurovent Certified Performance certification process. First, he explored the information required from the manufacturer and Eurovent Certification prior to product testing, before moving onto the test preparation and setup. Once testing is complete, he explained that a report with conversion to standard conditions was produced and sent to Eurovent Certification, who then evaluated the results and classified the product against an energy efficiency class. If the values are within tolerance range, the test is successful. However, if it is not, then corrective measures must be taken by the manufacturer.
Peter then ran through the testing of several cold chain refrigeration products including condensers, CO2 gas coolers, dry coolers, refrigerated display cabinets, fan convectors, sample boxes (for ventilation units), air handling units, cooling towers, heat pumps, and air conditioners, before moving onto certification for transport refrigeration. Next, he covered key topics such as partial load and new refrigerants, along with the important topic of safety requirements.
Peter finished by summing up the vital parts of his presentation and by stressing that in today's multi-functional landscape, only a system with constant monitoring, combined with control of production quality and supplier parts, can guarantee the specified performance values. He then took questions from the audience.
