摘　　要：以北京地区某临街办公建筑为研究对象,实时监测室内外PM2.5的计重浓度。通过对检测结果的分析得出:室外PM2.5污染较为严重;室内无污染源情况下,室内外PM2.5质量浓度成正相关、室内PM2.5的质量浓度低于室外;室内外质量浓度比(I/O)随气象参数变化波动范围较大。根据监测结果,为了有效解决集中空调系统室内PM2.5的污染问题,本文对现集中空调系统常用的G4+F7以及G4+F9两种不同空气处理机组的过滤器配置方式进行了实验研究。过滤器性能试验表明,G4+F7和G4+F9两种组合均可有效去除PM2.5。A real-time monitoring was conducted on a roadside office building to obtain mass concentration of indoor and outdoor PM2.5 in Beijing. The analyses ol the momtormg results snoweo mat, outuoor PM2.5 pollution was more serious; in the absence of indoor pollution source, the mass concentrations of indoor and outdoor PM2.5 were positively correlated, and the mass concentration of indoor PM2.5 was lower than that of outdoor PM2.5 ; I/O ratio fluctuated in a wide range with the change in meteorological parameters. According to the monitoring results, in order to effectively address indoor PM2.5 pollution problems caused by central air-conditioning system, an experimental study was carried out to investigate the filter configuration of two common air handling units （ G4 ＋ F7 and G4 ＋ F9 ） of central air-conditioning system. Furthermore, filtration efficiencies of PM2.5 under these two configuration modes were also explored. Filter performance test showed that the two configuration modes can be effective removal of PM2.2.
