The present invention provides a refrigerant with a comprehensively lowered environmental impact, including a low global warming potential resulting in an excellent effect on direct environmental impact, and a good energy efficiency when charged into an apparatus resulting in an excellent effect on indirect environmental impact, and low LCCP. Specifically, the present invention relates to a refrigerant composition containing 10 to 26 mass% of difluoromethane (HFC32) and 74 to 90 mass% of 2,3,3,3-tetrafluoropropene (HFO1234yf). |
