Abstract：
This article aims at the influence of outdoor PM2.5 source, analyses the chief factors that affect the indoor PM2.5, including air volume, filtration efficiency and indoor air organization, etc. According to these factors, we propose the indoor PM2.5 control technology suitable to the residential building: using the PM2.5 filtering fresh air system for residential. Then we analyses the main requirements (including ventilation rate, filtration efficiency, target indoor PM2.5 concentration), the system type and the principle of air supply and return. Aiming at the residential PM2.5 control system, the mathematical model is established, the calculation input conditions are determined, the theoretical calculation is carried out, and the indoor PM2.5 control effect is analyzed. According to the theoretical calculation results, when the air tightness of the enclosure structure is nice, the PM2.5 filtering fresh air system for residential can effectively control the indoor PM2.5 concentration.
