| 摘 要： | 基于热力学第一定律,反映热泵能量数量关系的性能指标-供热系数,在用于评价热泵系统节能效益及对热泵系统进行可行性评价的问题上,存在一定的局限性。本文对这一问题进行了分析。在此基础上,根据热力学第二定律,提出了以热泵系统单位火用损供热率作为其性能评价指标的思想。以此作为热泵系统的性能评价指标,更科学、更客观。

| Abstract: | Based on the first law of thermodynamics,the coefficient of performance(COP) of the heat pump system,which reflects the quantity relation of input and output energy,has certain limitation on the evaluation of energy saving efficiency and the feasibility of the heat pump system.Based on the analysis of this problem and the second law of thermodynamics,a new performance index called the heating load of unit exergy loss is proposed,which reflects energy saving efficiency and the feasibility of the heat pump system more scientifically and more objectively. |

| Keywords: | heat pump system performance evaluation coefficient of performance heating load of unit exergy loss |
