摘要
本文研究了牛顿定律系统广义不可逆卡诺制冷机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制冷机的最优利润率解析式以及相应的制冷系数界限,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 exergoeconomic performance of a Newtonian law system generalized irreversible Carnot refrigerator 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 refrigerator model are derived. Furthermore, the comparative analysis of the influences of various factors on profit rate and finite- time exergoeconomic performnce bound of the generalized irreversible Camot refrigerator is carried out by detailed numerical examples.
