A3 refrigerant R290 leak and ignition testing for refrigerated display cases.

Author(s) : WANG X.

Summary

R290 (propane) is a flammable refrigerant having an A3 classification according to the ASHRAE Standard 34. Because of its extremely low Global Warming Potential (GWP), several regions around the world use or consider using it for refrigeration applications. On the other hand, the R290 application was limited to small charged self-contained products in most of the world due to its high flammability and safety implications.
The Air-Conditioning, Heating, and Refrigeration Technology Institute (AHRTI) conducted the R290 leak and ignition testing under whole room scale conditions. This paper summarizes the test results for a single door and a three-door refrigerated display cases in a full-scale room. The testing simulated refrigerant leaks from the display cases with ignition sources present. R290 charge levels ranging from 114g to 400g were tested. The tests also included using the condenser fan circulation to disperse leaked refrigerant as a mitigation method.
