The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) is in the midst of a Low Global Warming Potential Alternative Refrigerants Evaluation Program (Low-GWP AREP). The approved test reports are due at the end of the year or early 2013, but some preliminary results were presented during the 14th International Refrigeration and Air Conditioning Conference recently held at Purdue University in West Lafayette, Ind.
The cost-effectiveness of refrigerants were reviewed in a report titled “Lifecycle Climate Performance (LCCP) of Various Refrigerants and System Options” from Emerson Climate Technologies that was presented at the fall Food Marketing Institute and Store Development Conference in Phoenix.
