热漏对制冷机制冷率制冷系数特性的影响

The Influence of Internal Heat Leak on the Rate of Rerfrige-ration Versus Coefficient of Performance of Refrigerators

本文研究热漏对制冷机最优性能的影响,导出存在外热阻和内热漏损失的定常态不可逆卡诺制冷机最佳制冷率、制冷系数关系,所得结果与仅存在热阻损失时的内可逆卡诺制冷机制冷率制冷系数特性关系有量和质的区别。

The influence of internal heat Leak on the optimal performance of refrig'e-rators was studied in this paper. The relation between optimal rate of refrigeration and coefficient of performance for a steady-state irreversible refrigerator with irreversibilites of external heat resistarce and internal heat leak wes derived. The rate of refrigeration versus coefficient of performance characteristics obtained here was different quantitatively and qualitatively from which for an endoreversible refrigerator.
