Abstract

The vortex and backflow phenomenon caused by many unreasonable designs in the indoor air environment make the velocity, pressure and temperature field distributed unevenly. These results bring out the indoor volatile pollutants local concentration is high. With numerical simulation analysis to pollutant flow field, the benzene concentration, temperature, relative humidity and the change of airflow velocity on the height direction were studied. The influence affected by indoor air change, temperature, relative humidity to pollutant diffusing dilution was discussed. The result analyzed indoor environment pollutant artificial guide flow diffusion mechanism can be a reference for solving these pollution problems. The results indicate that the benzene can be removed from the room effectively through increasing the indoor temperature, relative humidity and adding replacement ventilation quantity.
