对车载空气净化器净化性能评价方法的探讨

摘要

30 car air purifiers (in view of family car) are selected in 3 m3 experiment module for testing, clean air delivery rate (CADR) and purification efficiency are used to evaluate the purifying effect of car air purifier on formaldehyde and particle pollutants, and the paper discusses the method differences. Testing result shows that it is proportional to both of them, when CADR formaldehyde≥12 m3/h and CADR particles≥15 m3/h, CADR can reflect the differences in purification capacity, and it can help consumers understand the real purification capacity of car air purifier in combination with purification efficiency.%选取30个车载空气净化器（针对家庭用车）在3 m3实验舱中进行测试，通过“洁净空气量（CADR）”和“净化效率”2种方法来评价车载空气净化器对甲醛及颗粒物污染物的净化效果，并就方法的差异展开探讨。检测结果表明，两者成正比关系，当CADR 甲醛≥12 m3/h、CADR 颗粒物≥15 m3/h时，CADR更能体现净化能力差异，结合净化效率，能帮助消费者了解车载空气净化器真实的净化能力。
