会议室环境中可吸入颗粒物浓度分布研究

Research on concentration distribution of inhalable particles in meeting rooms

在进行了大量实际监测的基础上选择两处有代表性的会议室作为监测对象,分析了室内颗粒物质量浓度分布情况及影响因素。研究结果表明,室内小粒径(小于1μm)颗粒物质量浓度所占比例大且存在状态稳定,大粒径颗粒物的质量浓度波动主要是由室内人员走动等造成的。

Based on a great deal of field monitors choosing two typical meeting rooms as supervision objects, analyses the mass concentration distribution and influencing factors of indoor particles. The result indicates that in meeting rooms, smaller size （less than 1 μm） particles have higher mass concentration than others and exist stably, and that the fluctuation in mass concentration of bigger size particles is caused by peoples＇s moving and other factors.
