摘要:

室内空气质量越来越受到人们的关注,空气净化器作为改善室内环境的有效手段,逐渐走入千家万户。室外环境恶化、新冠疫情等因素使得消费者对空气净化器洁净空气量(CADR)的需求逐年增加,大风量空气净化器逐渐被应用于各类公共场合。本文对比了中国、美国、欧洲等国家和地区的空气净化器测试标准,发现仅有中国标准对大风量空气净化器相关的测试进行了补充,但对于洁净空气量与适配的测试舱体积仍值得继续研究。本研究利用不同体积的环境舱对大风量空气净化器进行了性能测评,从有效数据、环境舱内污染物均匀度及测试结果准确性等方面对环境舱体积与其适合的空气净化器风量进行了分析,结果可为相关测试方法及标准的制定提供参考。

Abstract:

The indoor air quality has been paid more and more attention by people. As an effective means to improve the indoor environment, the air purifier has gradually entered thousands of households. The deterioration of the outdoor environment, the epidemic situation of the COVID-19 and other factors make consumers’ demand for clean air delivery rate (CADR) of air purifiers increase year by year. High volume air purifiers are gradually used in various public places. This paper compares various test standards of air purifiers in China, the United States, Europe and other countries. It is found that only Chinese standards have supplemented the testing related to high air volume air purifiers, but there is still room for further research on CADR and suitable test chamber volume. In this study, the performance of high air volume air purifier is evaluated by using test chamber with different volumes. The volume of test chamber and the air volume of the air purifier are analysed from the aspects of effective data, the uniformity of pollutants in the chamber and the accuracy of the test results. The analysis results can provide a reference for the formulation of relevant test methods and standards.
