| 摘 要： | 合理的建筑设计可增强室内自然通风，使室内环境的舒适性得到明显的改善。为了对比建筑设计对室内自然通风效果的作用，结合重庆市的最佳户型评选活动的部分建筑户型，利用数值分析的方法，对建筑进行了建筑布局和建筑朝向的不同设计情况下室内速度场分布、温度场分布和室内PMV分布的分析。分析表明，通过改变建筑朝向和局部改变建筑布局设计，室内产生的最大气流可从0．24m／s增强到0．82m／s，显著改善了室内的自然通风效果；半小时后室内温度较原朝向降低0．9℃，室内的PMV值更接近舒适。由此可见，建筑布局和建筑朝向的合理设计，是保证建筑良好室内舒适环境的前提。

| Abstract: | Indoor thermal comfort can be significantly improved by natural ventilation with reasonable architectural design. In order to compare natural ventilation effect, the distribution of velocity field, temperature field and the PMV in different architecture layout and orientation design were analyzed with house types in Best House Type Competition. It was found that indoor natural ventilation effect was obviously improved by means of altering the layout and orientation, where the maximum velocity varied from 0.24m/s to 0.82m/s. And the temperature decreased 0.9℃ and the value of PMV was more approximate to comfort. |
