摘要
建筑设计中室内PM2.5的控制策略与室内发尘、室内外浓度等参数有关。本文通过建立和简化室内PM2.5宏观质量守恒模型,提出设计过程中的空气过滤器选型方法。设计参数建议室外采用城市年不保证10天浓度值,室内采用分级限值,以75μg/m3,50μg/m3和35μg/m3为标准进行划分。引入主要尘源相对人员的当量产尘系数,进而实现选型计算。最后综合阐述当前市场中各种类型空气过滤器产品的优缺点。
The control strategy of indoor PM2.5 concentration is related to indoor particulate emission rate,outdoor and indoor concentration and other parameters.The selection method of the air filter during the design is proposed based on the establishment and simplifying of PM2.5 mass conservation macro model.The outdoor particulate concentration is suggested to be the value of no guarantee for 10 days.The indoor concentration should be classified to different levels which are 75μg/m3,50μg/m3 and 35μg/m3 respectively.The equivalent emission coefficient on each person of main particulate is proposed,so that the selection calculation can be conducted.In the end,the advantages and disadvantages of different types of air filter products in present market are discussed comprehensively.
