摘要
随着国家的经济建设的快速发展,人们的生活水平有了很大的提升。在购买房屋时不但对户型的空间利用率有很高的要求,而且开始关注房间内的空气质量问题。均匀的风场是住宅的舒适性至关重要的因素,文章选取了两种不同的住宅户型,一种为穿堂风南北向贯穿客厅,南北均有窗,另一种只有南边有窗,基于流体力学分析软件CFD ANSYS for fluent建立住宅模型,模拟了两种户型的室内风环境,探究两种户型的空气流动的均匀性、流畅性。结果显示,南北通透户型的空气流通顺畅均匀,流动速度快,室内产生的涡流区域较少,换气效率高,而只有南向开窗的户型,空气流动缓慢或停滞,产生大量涡流区,不利于室内改善空气质量。文章希望为建筑设计工作者及购买房屋的消费者提供帮助。
With the rapid development of the country’s economic construction, people’s living standards have been greatly improved. When buying a house not only to door model space utilization rate has very high demand, and begin to pay attention to the air quality problem inside the room. Uniform wind field is the comfort level of the housing vital factors, this article selects the two different types of residential door model, a kind of for cross ventilation north-south through the sitting room, north and south have a window, another only the south window, based on fluid mechanics model for fluent CFD analysis software ANSYS to establish residence, two door model to simulate the indoor air environment, explore two kinds of model of air flow uniformity and smoothness. The results show that the air flow is smooth and uniform in both north and south, the flow speed is fast, the indoor eddy area is less, the ventilation efficiency is high, and only the south window door type, the air flow is slow or stagnant, creating a large number of eddy zone, which is not conducive to indoor improvement of air quality. It is hoped that this paper can provide help to architectural designers and consumers who buy houses.
