针对室内环境PM_(2.5)污染问题,设计了一台空气净化器,以强电场介质(Intense Field Dielectric,IFD)装置作为其核心过滤元件。在上海某办公室,以香烟烟雾为PM_(2.5)发生源,测试了净化器的一次过滤效率、风量、能耗、臭氧发生量,以及不同档位运行工况下室内PM_(2.5)质量浓度衰减情况和换气次数,并计算了各档位的洁净空气量(Clean Air Delivery Rate,CADR)和净化效能。结果表明,IFD装置能够有效净化实际环境中的高浓度PM_(2.5),其臭氧发生量符合环境要求。空气净化器在2档运行时,CADR和净化效能均较大。
Aiming at the problem of indoor PM_ (2.5) pollution, an air purifier was designed to use the Intense Field Dielectric (IFD) device as its core filter element. In an office in Shanghai, the PM_ (2.5) source of cigarette smoke was used to test the primary filter efficiency, air volume, energy consumption, ozone production and attenuation of indoor PM_ (2.5) concentration under different operating conditions Conditions and ventilations, and calculated Clean Air Delivery Rate (CADR) and purifying performance for each stall. The results show that the IFD device can effectively purify PM_ (2.5) in high concentration in the actual environment, and the amount of ozone produced accords with the environmental requirements. Air purifier in the second gear operation, CADR and purification efficiency are large.
