Document Type and Number:
WIPO Patent Application WO/2022/050351
Kind Code:
A1
Abstract:
The present invention inhibits propagation of a disproportionation reaction of a refrigerant. The present invention provides a use of a composition as a refrigerant for a refrigerant circuit (10), said composition containing one or more compounds selected from the group consisting of ethylene-based fluoroolefins, 2, 3, 3, 3-tetrafluoropropene (HFO-1234yf), and 1, 3, 3, 3-tetrafluoropropene (HFO-1234ze). The refrigerant circuit comprises a compressor (21), a four-way valve (22) and a first refrigerant pipe (11) which connects the compressor (21) and the four-way valve (22) to each other, while having a pipe diameter of 3/8 inch or less, or a length of 5 cm or more.
