Low-GWP Refrigerant Alternatives Being Evaluated
AHRI has posted nine final test reports for its Low Global Warming Potential Alternative Refrigerants Evaluation Program (Low-GWP AREP). The reports contain drop-in test results of low-GWP refrigerants in several different types of systems:
- Chillers
- Commercial ice machines
- Residential heat pumps
- Bottle coolers
- Trailer refrigeration
This Low-GWP AREP was started over two years ago. The alternative refrigerants are not ranked, however. The goal of the program was simply to identify potential refrigerant replacements for high GWP refrigerants (such as R404A, R134a, and R410A) and present performance of these replacements in a consistent and standard manner.
