Abstract：
PM2.5 pollution control design and calculation method includes indoor PM2.5 load calculation and air-treatment equipment capacity calculation. The calculation method was formulated according to the Practical Design Manual of Heating and Air Conditioning and five typical air-treatment systems were introduced. During calculation of indoor PM2.5 pollutant source load, simultaneity coefficient of pollutant sources shall be comprehensively considered. Pollutant sources shall not be summed up simply, but be calculated according to the possible practical activities in different buildings.
