建立一类低温热源有限的不可逆三热源制冷机模型，探讨有限热源，传热及工质内部不可逆性对制冷机性能的影响，导出制冷率与制冷系数以及火用损率与制冷系数和制冷率间的优化关系．由此讨论了制冷机的各种优化性能，所得结论可为三热源制冷设备的开发利用提供新理论指导．
An irreversible three heat source refrigerator model involving a finite low temperature source is set up , and the effects of finite low temperature source, heat transfer and irreversibilities inside a working fluid on the performances of the refrigerator are explored. The optimal relations between the cooling rate and the refrigeration coefficient and between the exergy loss rate and the refrigeration coefficient as well as between the exergy loss rate and the cooling rate are derived.On the basis of these relations, various optimal performances of the refrigerator are discussed. The conclusions obtained here may provide some new theoretical instructions for the development and utilization of three heat source refrigerators.
