Mixed refrigerants are obtained from mixing pure refrigerants in specific proportions and it is known as mixed refrigerants. Mixture refrigerants are divided into two groups according to their thermodynamic behavior: zeotropic mixtures and azeotropic mixtures. In this study, the performance of R410A refrigerant obtained from mixture of two pure refrigerants (R125 and R32) in vapor compression refrigeration cycle was investigated. The coefficients of performance (COP) of the cooling system under different operating conditions were investigated. The highest COP value for working conditions in this study was determined as 7.3. In addition, the capacity of the cooling system compressor has been determined for different operating conditions.
