Outdoor pollutants effect on air quality of air-conditioned room

With the improvement of people's living standards, people's demands on indoor air quality are increasingly higher and higher; whether the indoor air quality is good or bad is closely related to people's health and productivity. In order to determine penetrating the indoor particle concentration distribution in the office, the use of CFD simulation method for a certain office in different particle size, and particle pollutants concentration distribution under different air distribution form, has carried on the modeling and numerical simulation. Visualization results were achieved, and the simulation results are analyzed. Though CFD, the detailed information of indoor air flow field and the pollutant concentration field is given fast. Further research should be on indoor air environment pollutant concentration field distribution about changing exhaust system, different exhaust air and office location and other environment conditions providing methods and a theoretical basis.
