In this paper different literature about the experimental analysis of vapor compression refrigeration system by using the diffuser at inlet of condenser are studied. Coefficient of performance can be increased by reducing compressor work or by increasing refrigeration effect. A diffuser after compressor for a vapor compression system helps to reduce compressor work. The diffuser accepts a compressed liquid refrigerant from a compressor of a refrigeration system. The refrigerant coming out of the diffuser has higher-pressure level than that of refrigerant entering the diffuser. In the condenser, there is a drop in pressure across the tubes thereby increasing the power consumption of the compressor. This paper is a theoretical study about how diffuser will help to reduce the compressor work. Diffuser is the static device which converts the high velocity of liquid refrigerant coming out from the compressor into the pressure energy. Diffuser recovers the pressure without any work input. Refrigerant from the compressor discharge enters the diffuser and increases its pressure considerably.
