| Abstract: | A general cycle model of a multi stage irreversible combined refrigeration system is established. The influence of thermal resistance and heat leak on the performance of the cycle is studied. The coefficient of performance is taken as an objective function. The performance of the refrigeration system is optimized. The fundamental optimum relation between the coefficient of performance and the specific cooling rate is derived. The maximum coefficient of performance and the corresponding specific cooling rate are determined. Other optimum performances are also discussed. The results obtained here are of general significance and can reveal the general performance characteristics of refrigeration systems. |
