Abstract
The propagation of a disproportionation reaction of a refrigerant is suppressed. Disclosed is a method that uses a composition in a device, 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 heat capacity of a portion with a melting point greater than or equal to 1,000° C. in the device is greater than or equal to 6.5 J/K.
