摘要:
The present invention provides a non-flammable refrigerant, which is excellent in handleability while retaining the refrigerating capacity. Specifically, the present invention relates to a refrigerant composition comprising 36 to 50 mass % of 1,1,1,2-tetrafluoroethane (HFC134a) and 50 to 64 mass % of 2,3,3,3-tetrafluoropropene (HFO1234yf).
