Title:
USE OF COMPOSITION AS REFRIGERANT IN DEVICE, DEVICE, AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/025202
Kind Code:
A1
Abstract:
The present invention suppresses the propagation of a disproportionation reaction of a refrigerant. The present invention is a use of a composition as a refrigerant for an compressor (21), the composition containing one or more selected from the group consisting of an ethylene-based fluoroolefin, 2,3,3,3-tetrafluoropropene (HFO-1234yf), and 1,3,3,3-tetrafluoropropene (HFO-1234ze). The compressor comprises first to fifth heat absorption parts (51, 52, 53, 54, 55) that: include a section in which the melting point is 1000°C or higher and the heat capacity is 6.5 J/K or more; and constitute a refrigerant circuit (10), together with first to ninth refrigerant pipes (11-19), a gas-side refrigerant connecting pipe (5), and a liquid-side refrigerant connecting pipe (6).
