December 14, 2022      ARE YOU READY FOR A2L REFRIGERANTS?

Lisa Meline, Professional Engineer,  Meline Engineering Corporation, Sacramento, CA

Leakage from the present high-GWP refrigerants now in use has severe climate impact compared to the warming potential of straight carbon dioxide.  A shift to low-GWP refrigerants is being developed to comply with tighter regulation.  This migration requires different refrigerant compression equipment and will take some time to accomplish at scale.  A2L is a category of refrigerants with far less HFC’s (hydrofluourocarbons) that will make their way into building codes.
