Performance Investigation of VCRS system using diffuser at the inlet of compressor

Abstract

This paper gives the concept of vapour compression refrigeration system the use of diffuser to improve the coefficient of performance of device. To enhance the coefficient of performance, its miles require that compressor work need to lower and refrigerating effect ought to growth. Diffuser is the static device. It increases the pressure of flowing fluid by way of changing its kinetic energy. In vapour compression refrigeration machine, to keep away from the troubles of high speed refrigerant one of the manner is to use diffuser at condenser inlet. It smoothly decelerates the incoming refrigerant drift attaining minimal stagnation pressure losses and maximizes static pressure restoration. Due to stress healing, at equal refrigerating impact compressor has to do much less work. Hence, power consumption of the compressor might be decreased results into increase device performance.
