Experimental Performance Evaluation of Vapor Compression Refrigeration System for R134a and R152a

An experimental performance evaluation of a vapor compression refrigeration system with refrigerants R134a and R152a were done and there results were compared. According to the results refrigerant R152a have slightly higher coefficient of performance (COP) than R134a for evaporating temperatures ranging between -5°C and 10°C and condensation temperature of 44°C. Refrigerant R152a was found superior to Refrigerant R134a. Various parameters of performance such as Pressure ratio, Compressor work, Refrigeration effect, power per ton refrigeration, volumetric refrigeration capacity, compressor power, discharge temperature, mass flow rate were also investigated for various evaporating temperatures.
