摘要
按照传统设计方法很难准确计算高大中庭保持均匀热舒适性时各层的送风量。以深圳某商业综合体为模型,利用CFD软件分析了当采用"计算+经验"设计方法时会出现"上热下冷"状态,通过调整送风量试算得出了合适的风量、冷量分配比例,该比例能够保证建筑温室内温度的均匀性并满足人员的热舒适要求。
It is difficult to accurately calculate the air supply volume aiming to achieve the temperature uniformity of the atrium using the traditional method. This article analyzes the phenomenon of＂hot on top and cold in the bottom＂of a commercial building in Shenzhen when employing the ＂calculation ＋ experience＂method by means of the CFD software. By adjusting the air supply volume and cooling capacities of different floors, a proper ratio was obtained which can fulfill the temperature uniformity and satisfy people＇s thermal comfort.
