The performances of the different refrigerants mentioned have been compared and R-152a is found to be the most efficient one.Colmac Coil A+ Pro Parametric Selection Software creates custom air cooler designs quickly and easily.

Effect of degree of subcooling on these computed parameters are also computed in this present work. The parameters that are computed in this study are required compressor power, coefficient of performance (COP) and required mass flow rate of refrigerants. Effect of compressor isentropic efficiency and degree of subcooling is also taken into consideration for the simulation model. Simulation is done within the condenser temperature range of 25C to 45C and evaporator temperature range of 0C to -20C. A computational simulation model is developed and simulation is carried out using CoolPack software for analyzing the vapour compression refrigeration system performances. Abstract : A numerical simulation of vapour compression refrigeration system has been carried out using different refrigerants such as R152a, R404A and R600a.
