可吸入颗粒物通过建筑围护结构从室外渗透进入室内,是室内颗粒物不可忽视的重要来源。本文系统评述了室外颗粒物向室内渗透的最新研究进展,从室内颗粒物的质量平衡方程出发简要分析了室内颗粒物浓度的主要影响因素,辨析了颗粒渗透研究中穿透系数、渗透因子和室内外颗粒物浓度比等常用术语的区别与联系,从现场测试、实验室研究、模型研究三个方面总结了颗粒物渗透研究方法以及主要结论和成果,最后给出了相关研究分析建议和展望。旨在为可吸入颗粒物围护结构渗透相关研究工作厘清思路,为我国相关研究工作的深入开展奠定基础。
Inhalable particles penetrate into the room from the outside through the building envelope and are an important source of indoor particulate matter. This paper systematically reviews the recent research progress of outdoor particulate matter penetration into the room. Based on the mass balance equation of indoor particulate matter, the main influencing factors of indoor particulate matter concentration are briefly analyzed. The relationship between penetration coefficient, permeation factor and indoor / outdoor particulate matter concentration ratio And other commonly used terms and contact, from the field test, laboratory research, model studies summarized three methods of particle penetration studies and the main conclusions and results, and finally gives the relevant research and analysis recommendations and prospects. The purpose is to clarify the thinking of infiltration of respirable particulate matter surrounding structures and to lay the foundation for the further development of related research work in China.
