空气净化器细颗粒物去除效果的环境舱测试与实际评价
Environmental chamber testing and practical assessment of PM2.5 removal effect of air cleaners
摘要：
首先在环境舱中测试并分析了8台空气净化器去除细颗粒物（PM2.5）的性能，然后选择典型空气净化器测试其对学生宿舍中PM2.5的去除效果，并采用问卷调查的方式，研究了受试者对空气净化器实际效果的主观评价。实验结果表明，空气净化器在环境舱和实际环境中对PM2.5均有显著去除效果，受试者对颗粒物浓度的不满意度从83.8%降低至16.2%，对室内空气质量的不满意度从77.5%降低至7.0%。

Abstract：
Tests and analyses the performance of eight air cleaners for PM2.5 removal in an environmental chamber. Tests the PM2.5 removal effect in a practical dorm environment with a typical air cleaner. Studies the subjective assessment of the actual effect of air cleaners by questionnaire survey method. The results show that household air cleaners have obvious effect on removing PM2.5 in both chamber and practical environment, the predicted dissatisfaction (PD) reduces from 83.8% to 16.2% for particle pollution and from 77.5% to 7.0% for indoor air quality.
