| 摘 要： | 为了分析在自然通风状态下阳台对公寓室内气流组织及房间换气次数的影响机理, 对带阳台公寓和无阳 台公寓分别进行建模, 并利用ANSYS仿真软件对两种模型进行模拟, 得出以下结论:阳台对来流空气有一定的阻碍作用, 带阳台工况下的换气次数小于无阳台工况下的换气次数;带阳台和无阳台两种工况下, 随着气流吹入角度的增大, 阳台对换气次数的影响程度先增大后减小;带阳台工况下来流空气在阳台内形成涡旋, 涡旋改变了前窗空气流向。

| Abstract: | In order to analyze the influence mechanism of a balcony on air flow and ACH in an apartment under natural ventilation conditions, the apartments with balcony and without balcony are modeled separately, and the two models are simulated by ANSYS software. The following conclusions are drawn: the balcony has a certain hindrance to incoming air, and the ACH of the apartment with balcony is less than that without balcony;in both cases with the angle of air blowing increasing, the influence of the balcony on ACH increases first and then decreases; with the balcony the air flows to form a vortex, and the vortex changes the air flow direction of the front window. |
