Performance Analysis of Vapour Compression Refrigeration System under alternative Refrigerant

Abstract

The vapor compression cycle is used in most house hold refrigeration as well as in many large Commercial
and Industrial refrigeration systems. The main components in this system are compressor, condenser, evaporator and
expansion valve. It uses a circulating liquid refrigerant as medium which absorbs and removes the heat from the
space to be cooled and subsequently rejects the heat to atmosphere. When the use of R134a in Vapor Compression
Refrigeration systems, it causes has high Global Warming Potential to Ozone layer. In this work to overcome above
difficulties and to enhance the performance, the existed vapour compression refrigeration system is modified and
replaced the new refrigerant instead of R134a and different quality tests are conducted to fix leakages then after
completion of fabrication, the experiments are to be conducted at load and unload conditions and COP has been
calculated and compared. Finally overall performance has proved that the R600a refrigerant has high COP than the
R134a.
