摘　　要： 通过对HVAC&R系统环境性能评价方法的回顾,提出了一种新的评价方法。该方法基于专家问卷调查和层次分析法,确定各种环境影响因素的权重系数,根据各类污染物的排放总量和权重系数,计算各类污染物的当量值,将HVAC&R系统对环境的各类影响转化为一个统一的指标——黑点,从而直观、准确地表达HVAC&R系统对环境影响的大小。利用新方法对某办公楼空调系统的环境性能进行了模拟计算,结果表明该方法简单直观、切实可行。 Reviews the literatures on the assessment methods for the environmental performance of HVAC ＆ R systems, and puts forward a new method, in which based on expert questionnaire survey and analytic hierarchy process method, defines the weights of various environment influencing factors, calculates equivalence of various pollutants based on the emission quantity and the weights calculated of various pollutants, and unifies all the influencing factors to a new unit--black point, which expresses the environmental performance of HVAC ＆ R systems directly and precisely. Applies the method to calculating the environmental performance of the HVAC ＆ R system in an office building. The results show that the new method is simple and effective.
