对内可逆三热源制冷循环进行了探讨.指出它是在传热不可逆的条件下,工作在三个热源间的最优制冷循环,并导出其最佳制冷系数、最大制冷量等诸最优性能.同时阐了这些结果的重要意义及其在实际中所起的作用.还讨论了内可逆三热源制冷循环与内可逆卡诺制冷循环之间的内在联系和相互区别,以及把三热源循环视为一个二热源热机驱动一个二热源制冷机的等效联合系统的重要理论意义.
The reversible three-source refrigeration cycle is discussed, and it is pointed out that it is the optimal refrigeration cycle among the three heat sources under the condition of irreversible heat transfer and derives the optimal performance such as the optimal refrigeration coefficient and the maximum refrigeration capacity At the same time, the significance of these results and the role they play in practice are also discussed.The internal relations and mutual differences between the endoreversible three-heat source refrigeration cycle and the endoreversible Carnot refrigeration cycle are also discussed, and the three-heat source cycle The important theoretical significance of an equivalent combined system driven by a two-heat source heat engine and a two-heat source refrigerator.
