摘　　要：以反映制冷机制冷率与熵产率之间最佳折衷的"生态学"准则为目标,综合考虑热阻、热漏及工质内不可逆性,导出了时不可逆制冷机的生态学最优性能,由数值算例对不同损失情况下制冷机的性能变化规律进行了比较分析,本文结果对实际制冷机的设计工作具有一定的理论指导意义。Considering comprehensively the effect of heat - resistance, heat leak and internal irreversibility on the performance of Carnot refrigerator, the optimal ecological performance of Carnot refrigerator with another liner heat transfer law is derived by taking an ecological optimization criterion as the objective, which consists of maximizing a function representing the best compromise between the refrigeration rate and entropy production rate of refrigerator. Detailed numerical examples show the effect of different losses on the optimal performance of the irreversible refrigerator. The results can provide some theoretical guidance for the designs of practical refrigerator.
