                摘要:

                通过某气密性较好的办公房间的渗透通风实验,分析了室内外累积粒径颗粒物和分段粒径颗粒物的逐时质量浓度分布,以及室内外不同粒径颗粒物的质量浓度相关性。研究发现:不同粒径颗粒物的质量浓度相关性差异很大,小粒径颗粒物相关性较强,随着粒径的增大,相关性逐渐降低,当粒径大于5 μm时,室内外颗粒物质量浓度无明显相关性;分段粒径颗粒物的室内外质量浓度相关性更能反映建筑围护结构的阻隔性能和室内颗粒物的污染特征。

                Abstract:

                Through the infiltration ventilation experiment in an airtight office room, analyses the hourly mass concentration distributions of indoor and outdoor cumulative and segmented particle size particles, and the correlation of indoor and outdoor particles with different sizes. The results show that the correlation values differ from different size zones, the value reduces with the particle size increasing,and there is no direct correlation with particles larger than 5 μm. The indoor and outdoor segmented particle size analysis can reflect the barrier performance of building envelope and indoor pollution characteristics.
