AHRI to start A3 refrigerant risk tests

USA: The AHRI is to begin leak and ignition tests on propane in commercial and residential air conditioning and refrigeration applications.

Following its study on A2L refrigerant leaks and ignition testing completed earlier this year, the AHRI’s research arm, the Air Conditioning, Heating, and Refrigeration Technology Institute (AHRTI), will now focus on the use of the A3 refrigerant R290 (propane).

This Phase II study will conduct refrigerant leak and ignition testing under whole room conditions to understand the risk associated with the use of A3 refrigerants. Tests will be conducted at UL.

This project is financially supported by the California Air Resources Board (CARB) and is a part of the flammable refrigerant research programme supported by AHRI, ASHRAE, CARB and the US Department of Energy. The programme aims to establish a robust fact base about the properties and the use of flammable refrigerants.
