Document Type and Number:
Japanese Patent JP7354271
Kind Code:
B2
Abstract:
A refrigeration cycle apparatus according to the present disclosure includes a refrigeration circuit which includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion valve, and refrigerant is enclosed in the refrigeration circuit. The refrigerant contains three components R32, HFO1123, and R744 and, in a composition diagram in which a mass ratio between the three components is represented by triangular coordinates, the mass ratio between the three components falls in a range enclosed by a first straight line connecting a point A to a point B, where the point A represents 46% by mass of R32, 54% by mass of HFO1123, and 0% by mass of R744, and the point B represents 46% by mass of R32, 37.2% by mass of HFO1123, and 16.8% by mass of R744, a second straight line connecting the point A to a point C, where the point C represents 0% by mass of R32, 100% by mass of HFO1123, and 0% by mass of R744, a third straight line connecting the point C to a point D, where the point D represents 0% by mass of R32, 85.7% by mass of HFO1123, and 14.3% by mass of R744, and a first curve connecting the point B to the point D. All the three components each have a mass ratio of more than 0% by mass.
