The present invention relates to a mixed refrigerant composed of 'R32 and RC270 and R1234yf' which can be used as a refrigerant (hereinafter referred to as R) in a vapor compression refrigerator / air conditioner. More specifically, methane to mono chlorofluorocarbons have been widely used in the air conditioner (CHClF2, R22 or less HCFC22 quot;) relates to the three-way mixed refrigerant which can replace, the composition components R32 (methylene fluoride; CH 2 F 2) 15- 30% by weight, RC270 2-10% by weight, R1234yf 60-83% by weight, and the sum of the three refrigerants is 100%. This mixed refrigerant has a low global warming index (GWP) of 105-205, which is 5.9-11.5% lower than that of the existing R22, so it does not cause the ozone layer collapse and the global warming index is much lower than that of existing refrigerants. It can be used as a refrigerant.
