| Abstract: | A four heat source endoreversible cycle model is used to investigate the performance of an absorption refrigerator affected by the irreversibility of heat transfer.The fundamental optimum relation between the cooling load per unit heat transfer area and the coefficient of performance of the cycle is derived and used to discuss the various optimum performances of the cycle.Some new significant results are obtained.Moreover,the irreversible factor is introduced to analyze the influence of the internal irreversibility of the working substance,so that the results obtained here are more realistic and can play better an instructive role for the optimal design and operation of absorption refrigerators. |
| Keywords: | absorption refrigerator four heat source irreversible cycle cooling load coefficient of performance optimal analysis |
