Abstract: A novel low-GWP mixed refrigerant is provided. A composition comprising a refrigerant, the refrigerant comprising trans-1,2-difluoroethylene (HFO-1132(E)), difluoromethane (R32), and 2,3,3,3-tetrafluoropropene (HFO-1234yf), is provided, wherein when the mass % of HFO-1132(E), R32, and R1234yf based on their sum is respectively represented by x, y, and z, coordinates (x,y,z) in a ternary composition diagram in which the sum of HFO-1132(E), R32, and R1234yf is 100 mass % are within the range of a figure surrounded by straight lines C1D, DG, GH, HB?, and B?C1 that connect the following 5 points: point C1 (52.0, 36.9, 11.1), point D (44.0, 0.0, 56.0), point G (12.2, 0.0, 87.8), point H (0.0, 8.2, 91.8), and point B? (0.0, 36.6, 63.4), or on the straight lines C1D and B?C1 (excluding points D and B?).
