摘　　要："能效比EER是英制有量纲值"的观点是比较拘泥于对ASHRAE标准原文的认识。本文通过分析认为EER或COP既可以是英制,也可以是国际单位制(也称SI制)。究竟是英制还是SI制,取决于使用者在计算或表达EER或COP时冷(热)量单位的选取。在美国,英制单位的使用历史悠久、根深蒂固,在从英制往SI制过渡期间,也许在使用EER和COP时分别用英制和SI制表示比较有利于理解和区别,但不代表它们就必须是英制单位的量纲。The point that energy efficiency ratio is a British system dimension value is tied to the recognition of the original text of ASHRAE standards.EER or COP is taken for not only British system,but international system of units（also called SI） in this paper through the analysis.Whether the EER or COP is British system of units or International system of units depends on what the unit choosen when EER or COP is used.In USA,British system of units is old-line and inveteracy.In the transition period from British System to SI,perhaps in the use of EER and COP applying British system and SI is in favor of understanding and distinguish.However,it does not represent that they must be British system dimension value.
