厦门地区单侧通风房间的窗户开口形式对室内风环境的影响研究

摘要

针对厦门地区的气候特征及自然通风条件,对该地区建筑中有代表性的单侧通风房间进行简化抽象,得到五种不同通风开口形式的单侧通风物理模型,并加入不同楼层高度这一变量,运用CFD方法对其进行模拟研究.通过分析模拟结果得出,楼层高度可影响进入室内的风速、方向以及室内风场的分布,在单侧通风模型迎风面的竖向增设通风开口可在局部或整体上提高室内通风效果并且可以增强地面除潮和室内采光效果,但仍需从构造上解决此类开口形式的防水等问题.%Based on the climatic characteristics and natural ventilation conditions in Xiamen,by simplifying and abstracting the representative one-side ventilation room which existing in buildings there,the paper obtained the physical models of single ventilation with five different ventilation openings.Besides,the paper also added the variable of different floors height and carried out a simulation research through the computational fluid dynamics technology.By analyzing the simulation results,it can be concluded that the height of the floor can affect the wind speed,direction and the distribution of the indoor wind field.The new vertical ventilation openings in the windward side of the single-side ventilation model can improve the indoor ventilation effect locally and in whole,and enhance the surface dehumidification and indoor lighting effect.But the structure such as the waterproof ability of such ventilation opening forms should be solved.
