ABSTRACT

Abstract: - At first glance, calculating the efficiency of any type of compression system seems to be straight forward Comparing the work required of an ideal compression process with the work required of an actual compression process. But the difficulty lies in defining appropriate system boundaries that include losses associated with the compression process. Generally the losses that occur in the refrigerant compressor are Electric motor losses, Mechanical power distribution losses, Heat losses, Cycle losses, Volumetric efficiency losses.The EER (Energy Efficiency Ratio) of the refrigeration and Air Conditioning system is improved by improving the cooling capacity (or) by reducing the power input to the compressor and by reducing the losses. In this project the parameters affecting the performance of reciprocating compressor are analyzed and appropriate modifications have been made which resulted in improving the performance (or) EER of the system.The modifications made are Surface finish improvements and usage of low viscosity co mpressor oils to reduce frictional losses between the mating parts. Reducing the displacement volume and suction valve leaf thickness to reduce the volumetric losses. Finally changing the suction head material from metal to plastic so as to reduce the heat losses and thereby improving the thermal efficiency
