Review on Performance analysis of Vapour Compression Refrigeration System by using Microchannel heat exchanger

Most of the household refrigerators work on the Vapour compression refrigeration system which has high coefficient of performance. The system consists of components like compressor, condenser, expansion valve and evaporator. The system performance depends on the influence of all the components of the system. This paper presents the study of performance of different condenser by changing the pressure and change in COP of vapour compression refrigeration system, by changing the conventional condenser by micro channel heat Exchanger. Due to change of pressure there are changes in heat transfer rate for different condenser. Hence it is very essential to study and check the heat transfer mechanism occurring at condenser section. The heat transfer will help to study and control the various heat losses occurring at condenser section. In this paper coefficient of performance of different condenser is compared at different pressure and it is found that microchannel condenser gives higher performance than other condenser and also vapour compression refrigeration cycle gives different COP at different pressure.
