Abstract

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently completed the first phase of its low global warming potential alternative refrigerants evaluation program (Low-GWP AREP). This industry-wide cooperative research program identified and evaluated promising alternative refrigerants’ performance over the past two years. Thirty-eight low-GWP refrigerants were tested during the first phase of the program in a variety of products; including air conditioners, heat pumps, chillers, ice makers and commercial bottle coolers. This paper provides a comprehensive summary of the test results obtained during phase I. Furthermore, AHRI is launching a second phase of testing at the beginning of 2014 that includes newly developed refrigerants and performance testing under high ambient conditions that were not covered in the first phase. A status update of Phase II testing will also be provided.
