Study on the Influence of Window Type on Natural Ventilation Effect Based on CFD Simulation
School of Energy and Environmental Science, Solar Energy Research Institute, Yunnan Normal University, Kunming 650500, China
Good natural ventilation is one of the basic conditions for people to be able to work and live indoors. In this paper, wind velocity, wind velocity non-uniformity coefficient and air age are taken as the evaluation indexes of indoor ventilation condition. A simulation software Airpak is used to build room models with three window types (with the same ventilation area), namely, top-hung window, casement window and sliding window. The wind incidence angle was adjusted between 0°- 90°, and the indoor wind velocity and air age of the room were simulated when the casement window was opened at 90°, the sliding window was fully opened and the top-hung window was opened at 30°. The average wind velocity, wind velocity non-uniformity coefficient and air age of the room under each working condition were calculated and analyzed to evaluate the freshness and comfort of the indoor air, so as to provide guidance for the reasonable design of indoor layout.
