Exergy Analysis of a Domestic Refrigerator with R134a

In this study, exergetic analysis of a domestic freezer-refrigerator in one ON-OFF cycle is presented. Relative irreversibility of the components is plotted versus time. The results show that the maximum exergy destruction occurs in the compressor followed by the condenser, capillary tube, freezer evaporator, refrigerator evaporator and superheating coil, respectively. Furthermore, the amount of exergy destruction of all components except the compressor decreases by time. According to the results, compressor improvement highly enhances the cycle
