Use of composition as refrigerant in compressor, compressor, and refrigeration cycle apparatus

Abstract

The propagation of a disproportionation reaction of a refrigerant is suppressed. Disclosed is a method of using a composition as a refrigerant in a compressor, in which the composition includes one or more compounds selected from the group of ethylene-based fluoroolefins, 2,3,3,3-tetrafluoropropene, and 1,3,3,3-tetrafluoropropene, and the dimension of a gap of a predetermined portion through which the refrigerant flows around an ignition energy generation portion in the compressor is less than or equal to 2 mm.

Dependencies are inferred from the claim text.
