PURPOSE: An alternative refrigerant mixture is provided to not influence to an ozone layer, to have a global warming potential much lower than other refrigerant, and to replace HCF22 without high remodeling existing compressors. CONSTITUTION: An alternative refrigerant mixture is a two-component mixing coolant consisting of R32 and R1234yf. The mixed-refrigerant consists of 70-80 weight% of R1234yf and 20-30 weight% of R32. The ozone layer depletion potential of the R1234yf is 0.0 and the global warming potential(GWP) is 113-136. The global warming potential(GWP) of the mixed refrigerant is 113-168.
