Improving the Performance of Vapour Compression Refrigeration System by using Useful Superheating

Vapour compression refrigeration systems are widely used refrigeration method in industries as well as domestic applications from a long times. There were many improvements made to get higher performance of such systems. In this paper we discuss about improvement way of such systems by useful superheating of refrigerant before entering to the compressor. The analysis shows that how could increase the performance of vapour compression systems by useful superheating occurring in evaporator to producing extra refrigerating effect. This might be possible if the heat absorbed for superheating purpose produce the additional cooling effect. The superheating of refrigerant also provide the safe working condition of compressor. The working conditions are: condenser and evaporator pressures of 7.2 bar and 2.2 bar respectively, R-12 used as a refrigerant and superheating of 10 ℃. The analytical comparison shows the way to give the preference to such superheating under the working conditions mention above.
