Experiment and CFD Simulation Study on Indoor PM2.5 Concentration Control in Office Buildings

In order to further study the law for the change of PM2.5 concentration in atmospheric environment impact on the indoor environment, projects use the experimental and CFD simulation method to quantitatively calculate the PM2.5 emission rate of cigarettes which is the main pollution sources of office building indoor. At the same time the method of experiment was used to verify the indoor PM2.5 control theory based on mass balance of indoor PM2.5 concentrations, and thus for the further study of PM2.5 and control of indoor PM2.5 concentrations provides certain scientific basis and theoretical guidance.
