摘　　要：本文以不可逆量子谐振子卡诺制冷机为研究对象,以利润率为目标,以循环中2个等温过程中工质温度为优化变量,采用数值计算方法,分析和优化了其有限时间■经济性能,并详细分析和讨论了各种损失项和价格比对其最优性能的影响。By taking an irreversible quantum harmonic Carnot refrigerator as research object and profit rate as optimization objective, this paper analyzes and optimizes finite time exergoeconomic performance of the refrigerator with numerical examples. In the optimization, the selected optimization variables are the temperatures of the working medium in the two isothermal processes. This paper also analyzes and discusses the influence of various loss issues and price ratio on the optimal performance.
