Exergy analysis of a Vapour Compression Refrigeration system with R-22, R-407C and R-410A

0
The parametric investigations of actual Vapour Compression Refrigeration (VCR) cycle in terms of Coefficient of Performance (COP), Exergy Destruction (ED) and exergetic efficiency of refrigerants R-22, R-407C and R-410A have been predicted with the help of a developed computational model. The present investigation has been carried out for evaporator and condenser temperatures in the range of -38?C to 7?C and 40?C to 60?C respectively. The results indicate that COP and exergetic efficiency for R-22 are higher in comparison to R-407C and R-410A. The optimum evaporator temperature for minimum ED ratio has been evaluated at various condenser temperatures.
