In this paper, Performance of serpentine condenser sub cooling effect on the vapour compression refrigeration system using R600a is presented, which operates using directly alternatives refrigerants, have poorer energy parameters compared with R134a.The cooling capacity amounts are also desired to be kept constant while changing the refrigerant of the systems originally designed and constructed to work with R134a. In order to achieve this aim, performance of R600a refrigerant was investigated by a serpentine condenser to following Liquid-suction heat exchanger for a refrigerator operating with R134a .Therefore, smaller discharge pressure of the compressor ,decreased electricity consumption ,increased in sub cooling temperature and enhanced cooling capacity amounts were intended in this study. The results obtained through this study have shown that, in the sub cooling temperature interval from 0°C to 14°C, the condenser additive surface is lower for R600a refrigerant compared to R134a COP increased up to 16.5% under a sub cooling temperature of 8°C to 14°C. The results in increased of COP in vapour compression refrigeration system as a result of using R600a as an alternative to R134a with the presence of a serpentine condenser and Liquid-suction heat exchanger in the system
