        摘要:

        设计了一台可置换多种过滤单元的室内空气净化器,在上海某办公室,测试并分析了强电场介质(IFD)装置、高效空气过滤器(HEPA)(1)、粗效滤网+驻极体、粗效滤网+静电纺和粗效滤网+HEPA(2)+活性炭过滤单元的净化特性,包括一次过滤效率、风量、能耗、细颗粒物(PM2.5)去除效果和臭氧发生量,计算了洁净空气量CADR和净化效能。结果表明:不同过滤单元均能有效净化香烟烟雾产生的PM2.5;HEPA(1)、粗效滤网+驻极体的CADR和净化效能均较大,其次是粗效滤网+静电纺、粗效滤网+HEPA(2)+活性炭,IFD装置的CADR最大,但净化效能最低。

        Abstract:

        Designs an indoor air cleaner with replaceable filter unit. Tests the filtration performances of intense field dielectric (IFD) device, high efficiency particulate air filter (HEPA)(1), primary effect filter combining with electret air filtration material, primary effect filter combining with electrostatic spinning air filtration material, and superposition of primary effect filter, HEPA(2) and activated charcoal filter in an office in Shanghai, including singlepass removal efficiency, air volume, energy consumption, PM2.5 removing effect and ozone generation. Calculates the clean air delivery rate (CADR) and filtration efficiency. The results show that each air filter unit can significantly remove the PM2.5 generated by cigarette smoke. HEPA(1) and primary effect filter combining with electret air filtration material have higher CADR and filtration efficiency, followed by primary effect filter combining with electrostatic spinning air filtration material and superposition of primary effect filter, HEPA(2) and activated charcoal filter. IFD device has the highest CADR but the lowest filtration efficiency.
