WIPO Patent Application WO/2023/181403
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises a refrigeration circuit including a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion valve, wherein: a refrigerant is enclosed in the refrigeration circuit; the refrigerant contains three components R1234yf, HFO1123, and R290; a composition diagram in which the mass ratios of the three components are represented by triangular coordinates includes a point A indicating that R1234yf/HFO1123/R290 = 100/0/0 in terms of mass%, a point B indicating that R1234yf/HFO1123/R290 = 85/0/15 in terms of mass%, a point C indicating that R1234yf/HFO1123/R290 = 20/80/0 in terms of mass%, and a point D indicating that R1234yf/HFO1123/R290 = 6.2/78.8/15 in terms of mass%; the mass ratios of the three components fall within a first range surrounded by a first straight line connecting the point A and the point B, a second straight line connecting the point A and the point C, a third straight line connecting the point B and the point D, and a first curve connecting the point C and the point D; and the mass ratios of the respective three components are larger than 0% by mass.
