摘　　要：以反映热泵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卡诺热泵的生态学最优性能,由数值算例对不同损失情况下热泵的性能变化规律进行了比较,其结果对实际热泵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 heat pump, the optimal ecological performance of Carnot heat pump 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 rate of heat pumping and entropy production rate of pump. Detailed numerical examples show the effect of different losses on the optimal performance of the irreversible pump. The results can provide some theo- retical guidance for the designs of practical pump.
