具有外热阻内摩擦和冷头热漏制冷机的最大制冷系数

The Maximum Refrigeration coefficient of a Refrigerator with External Heat Resistance, Internal Friction,Cold End Heat Leak

采用有限时间热力学研究了传热热阻，内部摩擦和冷头热漏三种不可逆损失对制冷机最优性能的影响。导出具有传热热阻，内部摩擦和冷头热漏不可逆损失的不可逆卡诺制冷机的最大制冷系数。

Using finite-time thermodynamics, it is investigated that the optimal function of a refrigerator is affected by three kinds of irreversible of heat resistance, internal friction and cold end heat leak. The maximum refrigeration coefficient of an irreversible Carnot refrigerator is derived.
