摘　　要：建立自然通风住宅房间室内PM_(2.5)浓度质量平衡方程,以日常室内无明显污染状况和室内吸烟状况为例对PM_(2.5)浓度进行监测,分析室内PM_(2.5)污染特征与控制效果。研究表明:一般住宅室内PM_(2.5)平均发尘量为1.9~3.8 mg/h;存在吸烟状况时,PM_(2.5)平均发尘量为3.4~9.7 mg/h,吸烟对室内PM_(2.5)浓度有显著影响,PM_(2.5)浓度最大值可达650~750μg/m^3,当自然通风换气次数从0.5 h^(-1)增加至0.8 h^(-1),室内PM_(2.5)浓度降低39%。同时关窗会增加室内PM_(2.5)浓度,此时使用净化器可降低室内PM_(2.5)污染,门窗开启1/3状态下室内净化器的CADR值为215 m^3/h,相比实验舱标定工况320 m^3/h衰减33%。This paper conducts a theoretical and experimental measurement analysis on PM（2.5） pollution characteristics and control effect of no obvious pollution and indoor smoking in residential buildings through establishing a mass balance equation of natural ventilation. The results showed that the average dust emission of PM（2.5） was 1. 9 - 3. 8 mg/h,when smoking was present,the average dust emission of PM（2.5） was 3. 4 -9. 7 mg/h, smoking had a significant effect on indoor PM（2.5） concentration,and the maximum concentration of PM（2.5） was 650 -750 μg/m3. Indoor PM（2.5） concentration decreased 39%when the natural ventilation rate increased from 0. 5 h（-1） to 0. 8 h（-1）. Meanwhile,indoor PM（2.5） concentration increased when the windows were closed,at this time using the purifier could reduce indoor PM（2.5） pollution,the CADR value of purifier was 215 m3/h in actual buildings of natural ventilation at the condition of doors and windows open 1/3 status,compared to the experimental room calibration conditions（ 320 m3/h）,the value decreased by 33%.
