摘　　要：应用有限时间热力学理论,基于利润率为目标函数,对牛顿传热规律下四热源吸收式制冷机进行优化分析,导出制冷机的经济优化性能,揭示了其与生态学优化性能的内在联系。所得结论可为四热源制冷机的优化设计和最佳工况选择等提供些新理论依据。Using finite-time thermodynamics, the optimal analysis of a class of four-heat-source refrigerator for Newton heat transfer law was done based on the rate of profit objective function. The exery economy optimal performances of refrigerator were derived and the internal relation between it and the ecological optimal performance was revealed. The conclusions obtained here may provide some new theoretical guidance for the manufacture and the optimal design of three-heat-source refrigerator.
