两级串接的内可逆制冷机的最优构形

Optimal Configuration of Two Endoreversible Refrigerators in Series

文中导出两级串接的内可逆制冷机在循环周期和每循环从低温热源吸取的热量一定时,所能达到的最佳制冷系数的表达式。并且讨论了热传导系数及中间热源热容量有限,对串接制冷机上作性能的影响,

In this paper, the expression of optimal coefficient of Performance obtainable from two endoreversiblc refrigerators in series under a given cycle time and the heat obsorbed from low-temperature heat reservoir Per cycle are derived, Moreover, the influence of thermal conductances and finite heat capacity of intermediate heat reservoir on the performance of refrigerators in series is discussed.
