建筑室内细颗粒物污染控制设计方法研究

Study on design method of indoor PM2.5 pollution control

提出了基于"不保证天数"的细颗粒物(PM2.5)室外设计浓度的确定方法,并给出了我国主要城市PM2.5室外设计浓度。提出了室内PM2.5负荷的概念,并基于此给出了建筑室内PM2.5污染控制设计计算方法。研究了在特定尘源条件下各级过滤器PM2.5的计重效率,为过滤器选型提供基础数据。针对室外大气PM2.5情况,提出了系统的节能运行方案。

According to the days of allowable failure, presents a determination method of PM2.5 outdoor design concentration, and provides the PM2.5 outdoor design concentrations of main cities of China. Puts forward the concept of PM2.5 load, and based on this concept, proposes the design method of indoor PM2.5 pollution control. In order to provide basic data for air filter design and selection, studies the PM2.5 weight efficiency of different filters under the condition of specific dust source. According to the pollution degree of ambient PM2.5 concentration, proposes the systematical energy-saving operation plans for indoor PM2.5 pollution control.
