Refrigerants used in the cooling industry and released into the atmosphere cause global environmental problems. In the field of cooling and air conditioning, the use of chlorofluorocarbon and hydrochlorofluorocarbon is the main cause of thinning of the ozone layer and global warming. Replacing hydrofluorocarbons used as refrigerants with lower global warming potential (GWP) refrigerants is among the priority issues in preventing environmental problems. In this study, the energy parameters of R450A and R134a refrigerant fluids, consisting of a mixture of R134a / R1234ze (E) with low GWP ratio that can be used as an alternative to R134a, were analyzed theoretically and environmentally for a small capacity vapor compression cooling system. In the parameter analysis, two different evaporator temperatures (-150 and 150C) and condenser temperature (350C) were accepted.
