摘　　要：本文研究了牛顿定律系统广义不可逆卡诺热泵的有限时间火用经济性能,导出了存在热阻、热漏和其它内不可逆性时卡诺热泵的最优利润率解析式以及相应的供热系数界限,并用数值算例分析了热漏等因素对利润率和火用经济性能界限的影响。The finite time exergy economic performance of a Newtonian law system of generalized irreversible Camot heat pump with heat resistance, heat leakage and internal dissipation is investigated in this paper.The analytical formulas about profit rate and COP （coefficient of performance） of the heat pump model are derived.Furthermore, the comparative analysis of the influences of various factors on profit rate and finitetime exergy economic performance bound of the generalized irreversible Carnot heat pump is carried out by detailed numerical examples.
