摘要
阳台是影响住宅建筑室内自然通风效果的一个重要因素且具有较强的可干预性。利用Workbench软件中的Fluent模块对某热门户型在不同阳台装修情况下进行速度场和空气龄的三维数值模拟和分析,建立了四种不同工况下的计算模型,对不同工况的风场和空气龄的分布均匀度进行了计算和对比,研究了阳台装修对室内自然通风的作用。研究结果表明:该户型南北通透,自然通风效果良好;阳台开窗越大,自然通风效果越好;阳台开窗大小与其他迎风面窗户大小相近时,室内风场最均匀。
The balcony is an important influencing factor of the indoor natural ventilation effect of residential buildings and the effect can be improved.In this paper,velocity field and air age of a popular house type were simulated with FLUENT software.There were four different calculation models,and the distribution uniformity of velocity and air age were calculated and compared with other three models.The effects on indoor natural ventilation of balconies were studied.The results showed that the house type which is transparent from north to south had good natural ventilation effect.The wider balcony window opened,the better natural ventilated effect was;When the size of balcony window and other windward face window sizes were close,the indoor wind field was the most even.
