Abstract:
Provided is a refrigerant composition as a mixed refrigerant containing refrigerant components of difluoromethane (HFC32), pentafluoroethane (HFC125), and hexafluoropropene (FO1216). The makeup of the refrigerant components in the mixed refrigerant is configured such that a global warming potential (GWP) is 750 or less, a vapor pressure at 25° C. is in a range of 1.4 to 1.8 MPa, and a flame retardant parameter Fmix represented by formula (1) below is 0.46 or more. Fmix=ΣiFixi (1) Here, Fmix indicates a flame retardant parameter of the refrigerant composition, Fi indicates a flame retardant parameter of each of the refrigerant components, and xi indicates a molar fraction of each of the refrigerant components.
