COP and EER have been widely used as important indices to evaluate the performance of heat pumps and refrigerating units in China.Aiming at the inconsistent definitions of COP and disagreement about COP among national standards,as well as chaotic situations in documents and engineering practice,puts forward the classification of application conditions of COP and EER after analysing their history and relevant definitions in standards at home and abroad,in order to clarify their applicable ranges and eliminate different meanings.Suggests that the definitions of COP should be unified by relevant departments for reasonable application.%COP 与EER 作为评价热泵/制冷机组性能的重要指标,在我国已广泛应用。针对国标规范定义COP 的矛盾、分歧及在文献资料和工程实践应用中的混乱现状,从二者历史沿革、国内外相关标准规范的定义等方面进行了分析研究,提出了 COP 与EER 的应用条件分类,以划清二者使用范围,排除歧义。建议相关部门统一COP 定义,以便其合理应用。
