Abstract: This experimental work focuses the performance comparison of Vapour Compression Refrigeration System (VCRS) with mechanical subcooling. The experimental study of VCRS has been carried out with two categories such as air cooling and mechanical subcooling. The various performance measures like Coefficient of Performance, compressor input and condenser heat rejection rate and refrigeration effect are compared in these two categories at different evaporator loads (50,100,150,200,250 Watts) with respect to the results obtained. Mechanical subcooling provides a better performance as compared to conventional air cooled refrigeration system upto 22% improvement in COP, 8% improvement in refrigeration effect, 7% improvement in condenser heat rejected. The result provides that mechanical subcooling could be used to improve the performance of VCRS. This noval concept can be implemented in very large capacity of VCRS used in industrial refrigeration system.
