摘　　要：利用有限时间热力学理论,综合考虑热阻、热漏及其它内不可逆性,研究了传热规律服从Q∝(△T)n时不可逆制冷机的生态学优化性能,并由数值算例对不同损失、不同传热规律情况下的卡诺制冷机性能变化规律进行了比较,其结果对实际制冷机的设计工作具有一定的理论指导意义。Using the theory of finite time thermodynamics, the optimal ecological performance of irreversible Carnot refrigerator with the losses of heat-resistance, heat leak and internal irreversibility are derived, in which the heat transfer law between the working fluid and the heat reservoirs obeys the heat transfer laws of Q∝（AT）^n. Some numerical examples are given to show the effects of different losses and different heat transfer laws on the optimal performance of the Carnot refrigerator. The results can provide some theoretical guidance for the designs of practical refrigerator.
