In this analysis the Performance of Compression cycle is assessed theoretically with different refrigerants. In compression refrigeration system, Hydrofluoric refrigerants such as R134A and R404A are considered as a refrigerant by mixing of these as different mass fractions. Various performance measures like compressor, discharge temperature, pressure ratio, Volumetric cooling capacity, volumetric efficiency and mass flow rate are analyzed. The results are compared with halogenated refrigerant such as R134A and R404A for different condenser and evaporator temperature. The new blend gives performance better than existing refrigerant. The mixing or blended of two or more refrigerant with exact blending ratio gives the highest rate of COP and low ozone depletion potential. The exact mixture was identified by verifying the properties of selected refrigerants .There are various combination of refrigerants and the mixture should be selected based on theoretical calculation of Coefficient of Performance.
