Abstract

In this study, based on the numerical simulation, we investigated aerosol pollution diffusion in residential bathroom with exhaust vents at different positions and different ventilation methods. The results show that setting an air outlet under the side wall next to the toilet can discharge aerosol pollutants in time, which not only shortens the diffusion path of aerosol pollutants, but also optimizes the air organization form. The dry and wet separation of the toilet area and the wash area separated by a physical partition adopts the principle of "screen", which effectively blocks the transmission path of aerosol pollutants.
