Numerical Analysis on the Impact of Windows and Interior Doors on Indoor Airflow of Rural Residence

Abstract:

There are several factors impacting on the indoor airflows, such as building openings, ambient wind speed, occupants’ behavior and so forth. This paper concentrates on the impact of windows and interior doors on airflows in a rural multi-storey residential building. The indoor airflow simulation was carried out by using the CFD software. 3 states of interior doors were set, and 60 regions were arrayed in bedroom to observe the variation of airflows. According to data of regions, the uniformity of airflow and the thermal comfort were analyzed. Simulation results identified that closing interior doors will increase the mean age of indoor air about 7 times as it under the condition of opening doors, which is from 90s to 666s. It also shows that transom windows is beneficial to improve natural ventilation efficiency, as it can raise the average wind velocity by 40% when interior doors are closed.
