The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently released several final test reports for its Low Global Warming Potential Alternative Refrigerants Evaluation Program (Low-GWP AREP). The reports contain test results of low-GWP refrigerants for residential heat pump, water-cooled chiller and commercial ice machine applications, and also include the refrigerants’ compositions. “Eleven low-GWP refrigerants were tested, and their performance was compared to their respective baseline refrigerants, either R-410A or R-404A,” said AHRI president and CEO Stephen Yurek. “This is the first set of many reports that will be published as part of our research program.” Currently, tests are ongoing, but all are expected to be completed by early 2013. Test reports are released to the public as they are reviewed and approved by the AHRI Low-GWP AREP technical committee. Reports available online include: System Drop-in Test of R-410A Alternative Fluids in a 5-RT Air-Cooled Water Chiller; System Drop-In Test of L-40, L-41a and N-40b in Ice Machines; System Drop-In Test of R-32/R-152a (95/5) in Air Source Heat Pump; System Drop-in Test of Refrigerant R-32 in Split System Heat Pump; and Soft-optimized System Test of Refrigerant R-32 in 3-ton Split System Heat Pump.
