空气净化器性能评价指标——关于空气净化器几个问题的探讨（1）
Performance evaluation index of air cleaners—Discussion on several problems about air cleaners (1)
摘要：
空气净化器主要有3种运行工况——试验工况、引入新风的循环工况和室内自循环工况。分析表明，洁净空气量作为空气净化器的常用评价指标，不能准确反映这些工况下的净化能力，会引起混淆。探讨了空气净化器3种运行工况与洁净空气量的关系，并提出了一种新的性能评价指标——单位能耗的净化效能CPEE。

Abstract：
There are three main operating conditions of air cleaners, including test condition, indoor part-cycling condition and indoor self-cycling condition. The analysis results indicate that the clean air delivery rate (CADR), as a common evaluation index of air cleaners, can not accurately reflect the cleaning performance under the three operating conditions which causes some confusions. Discusses the relationship between three operating conditions of air cleaners and CADR, and puts forward a new performance evaluation index—cleaning performance under energy efficiency (CPEE).
