应用四热源内可逆循环模型研究吸收式制冷机受传热不可逆性影响时的性能。导出循环的单位面积制冷负载和制冷系数间的基本优化关系。由此讨论循环的各种优化性能 ,从而得到一些有意义的新结果。进而引进不可逆因子 ,用于分析工质内不可逆性的影响 ,使结果更接近于实际 。
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.
