摘　　要：基于传热规律Q∝△Tn,研究一类受热阻、热漏及循环内部不可逆性影响的卡诺制冷机,导出制冷机的最佳制冷率与制冷系数间的相互关系,并阐述了这一关系对研究实际制冷机的优化性能及性能界限具有重要意义.By applying the heat transfer law Q∝△Tn, a class of irreversible Carnot refrigerators affected by heat resistance, heat leak and internai irreversibilities is investigated, and the relationship between the optimal refrigeration rate and the performance coefficient of the refrigerators is derived. Moreover, the significance of using this relationship to study the optimal performance and performance bounds of a real refrigerator is also expounded.
