Study of Relationship Between Air Purifier Efficiency and Placement in Ventilation Environment

Air purifier was used more and more widely, its placement and characteristics of indoor air have a significant impact on the efficiency of air purifiers. Based on CFD software, the effect of five different ways of the placement were analyzed; according to experimental station, the effect of three cases were detected, which verified the correctness of the simulation. The results show that: the placement of the air purifier should be placed by considering the impact of air distribution, purifiers should be put in near the outlet, and far away from the return air, supply air could expand the work area of air purifier to achieve better effect It provide some basis for optimizing the use of air purifier and improving, indoor air quality.
