摘要
该文简要分析了室内颗粒物浓度的主要影响因素,归纳总结了室内颗粒源释放速率的主要计算方法,从颗粒物释放速率和粒径分布两方面详述了室内各类颗粒物源包括燃烧类、烹饪类、再悬浮类和其它类源的颗粒释放特征,同时分析了各类颗粒源释放率的影响因素。对民用建筑颗粒物污染源释放机理、规律特性的全面理解和把握,有助于从源头出发减少室内颗粒污染及人员暴露危害。
This paper analyzes the main factors of indoor particle concentration briefly and summarizes the major calculational methods of emission rates for the indoor particulate matter source. The characteristics of particle emission in various indoor particulate sources, including combustion, cooking, resuspension and other sources, are described in details from two aspects such as particle emission rate and particle size distribution. The factors affecting the emission rate of various particle sources are also analyzed. A comprehensive understanding of the emission mechanism and characteristics of particulate pollutants in civil buildings is helpful to reduce the indoor particle pollution and personnel particle exposure from the source of particulate matter.
