Study on design method of indoor PM2.5 pollution control

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.
