Composition containing refrigerant, use thereof, refrigeration method using the same, and refrigerator including the same

摘要

PROBLEM TO BE SOLVED: To provide a refrigerant composition having (1) low GWP, stability and temperature glide minimization characteristics, and (2) refrigerating capacity, compressor outlet pressure and COP comparable to those of R404A . A composition containing a refrigerant, the refrigerant containing difluoromethane (R32), trifluoroethylene (R1123) and 2,3,3,3-tetrafluoropropene (R1234yf), A (R32 / R1123 / R1234yf = 25.6 / 13.4 / 61.0mass%); Point B (R32 / R1123 / R1234yf = 25.6 / 3.4 / 71.0mass%); and Point C (R32 / R1123 / R1234yf = 3.9 / 36.5 / 59.6 mass%) The mass ratio of the three components is shown in the triangular composition diagram of FIG. 1 with the three components as vertices: within the area surrounded by the lines a, c and d connecting the three points There is a composition.
