The present invention provides a refrigerant composition that is nonflammable, and ensures low LCCP and less burden on the environment. More specifically, provided is a refrigerant composition containing pentafluoroethane (HFC125), 2,3,3,3-tetrafluoropropene (HFO1234yf), and 1,1,1,2-tetrafluoroethane (HFC134a), the ratio of HFC125/HFO1234yf/HFC134a being in a range surrounded by points (21/79/0 mass%), (28.5/71.5/0 mass%), (0/30.2/69.8 mass%), and (0/64/36 mass%) in a ternary diagram of a refrigerant composition containing HFC125, HFO1234yf, and HFC134a, and the composition essentially containing HFC134a and HFC125.
