A computational model based on exergy analysis of optimization of an ice-on coil thermal energy storage refrigeration cycle is developed in this paper. The method is based on exergy destruction analysis and optimization. As there are single and/or two phase refrigerant streams involved in the heat transfer and pressure drop in the compressor, condenser, expansion valve, evaporator, and between the ice tank and the environment, then there are irreversibilities or exergy destruction due to finite temperature difference and due to pressure losses. These two irreversibilities which represent the principles of components of the total irreversibilities are not independent and there is a trade-off between them. In this paper the effects of pressure drop ratio (PDR) in the evaporator and the condenser on the total number of exergy destruction units and the exergetic efficiency of a refrigeration cycle are determined. The pressure drop irreversibility to the total irreversibility for ΔPcond =25 → 100 kPa and PDR =1 are determined to be 7.45% → 27.08%.
