The ventilation effect in different places in the teaching building is different. The aim of this paper is to study the relative ventilation relationship of the rooms in "L" type middle school teaching building. Taking Xiamen in the subtropical region as a typical city, different aspect ratio for 1:1, 1:1.5 and 1:2 were set as variables, using the CFD simulation method. Combined and separated effects of the defined parameters on natural ventilation performance are evaluated using the ratio of age of air area as criteria. The result shows that the "L" type teaching building ventilated condition presents several characteristics as the approaching wind direction changed. Corner, long wing and short wing of building have some influences on the wind environment for classrooms. In addition, different aspect ratio "L" type buildings correspond to different optimal inlet wind angles. The research results in this paper can help architects to design buildings more scientifically and reasonably.
教学楼不同位置的通风效果各异。本文旨在研究“L”型中学教学楼内各房间的相对通风关系。以亚热带地区的厦门作为典型城市，将不同的长宽比1:1、1:1.5和1:2设为变量，采用CFD模拟方法。以空气龄面积比为标准，评估所定义参数对自然通风性能的综合和单独影响。结果表明，随着来风方向的改变，“L”型教学楼的通风状况呈现出若干特征。建筑的拐角、长翼和短翼对教室的风环境有一定影响。此外，不同长宽比的“L”型建筑对应不同的最佳进风角度。本文的研究结果有助于建筑师更科学合理地设计建筑。
