摘　　要：以反映制冷机火用输出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 ,导出了牛顿传热定律系统广义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。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 Newton 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.
