摘要
通过建立室内颗粒物集总参数模型,对自然通风房间室内的颗粒物污染特征及室内外颗粒浓度比值进行理论分析和实验研究,结果表明,室内PM10、PM2.5、PM1.0分别有46.7%~54.4%、48.7%~57.3%、22.9%~28.9%来自室内污染,室内外颗粒物的相关性随粒子尺度的增大而增强;测试房间PM1.0的I/O比在0.97~1.31内变化,PM2.5、PM10的I/O分别介于0.90~1.23、0.95~1.08之间,随着粒径的增大I/O比降低,其均值分别为1.09、1.06、1.00。
This paper conducts a theoretical.analysis and experimentally studies the characteristics of particle matter pollution and the ratio of the indoor to outdoor particle concentration of a natural ventilation building through establishing a mass balance equation. The results show that indoor PM10, PM2.5, PM1.0 are 46.7% -54.4%, 48.7%~57.3% , 22.9%-28.9% from indoor air pollution respectively, the correlation between indoor and outdoor particulate matter strengthened with the increase of the diameter, The I/O value of PM1.0 is in the range of 0.97-1.31, the PM2.5 and PM10 are in the range of 0.90-1.23and 0.95-1.08, the I/O value reduces with the increase of the diameter, the mean ratio are 1.09, 1.06, 1.00 respectively.
