9种住宅空气净化器的净化效果

Purification Effects of Nine Residential Air Cleaners

摘要

摘要:
目的评价目前市场上主要品牌住宅用空气净化器对空气污染物的净化效果。

方法采用30 m³环境测试舱法测试9种家用空气净化器对颗粒物、甲醛、总挥发性有机化合物(TVOC)、氨、二甲苯的净化效果,并以去除率、洁净空气量、净化效能等指标评价上述空气净化器的净化性能。

结果在所测试的净化器中,对甲醛、TVOC、氨、二甲苯的3 h去除率≥ 80%的净化器分别占测试总数的55.6%、88.9%、33.3%和88.9%。按甲醛、TVOC、氨、二甲苯净化效能符合《空气净化器》 (GB/T 18801-2008) (≥ D级)要求划分的净化器分别占测试总数的77.7%、88.9%、55.6%和100.0%;颗粒物净化效能符合《空气净化器》净化效能A级要求的空气净化器占测试总数的88.9%。

结论所抽检的家用空气净化器有机污染气体和颗粒物净化的总体性能良好,而对氨类的净化性能不足。

Abstract:
Objective To evaluate the actual performance of residential air cleaners by major manufacturers in the consumer market.

Methods The purification effects of 9 residential air cleaners were tested including particulate matter, formaldehyde, total volatile organic compound (TVOC), ammonia and dimethylbenzene in a 30-cubic-meter-volumn test chamber. The cleaning capability of the air cleaners were evaluated by comprehensive indexes of pollutants removal rate, clean air delivery rate (CADR), efficiency of clean etc.

Results Among the tested air cleaners, those with 3 h gaseous pollutants (formaldehyde, TVOC, ammonia and dimethylbenzene)removal rate higher than 80% accounted for 55.6%, 88.9%, 33.3% and 88.9% respectively. In testing the cleaning efficiency of air cleaners for gaseous pollutants (formaldehyde, TVOC, ammonia and dimethylbenzene), those meeting the technical requirements of "Air Cleaners" (GB/T 18801-2008) (≥ Grade D) accounted for 77.7%, 88.9%, 55.6% and 100.0% respectively. For particulate matter, 88.9% of air cleaners met the technical requirements of GB/T 18801-2008 (Grade A).

Conclusion The tested air cleaners show good performances in organic gaseous pollutants and particulate matter purification, but low ammonia cleaning capability.
