湿热气候区建筑天井的优化设计策略
Optimization design strategy of courtyard in hot and humid climate zone
摘要：
以三亚地区某多层天井式办公建筑为研究对象，采用数值模拟方法研究了天井的主要结构特性、底层架空方式和室外环境等因素对通风效果的影响。结果表明：当天井的长宽比为1∶1时，天井最佳设计高宽比宜取4∶1~5∶1；底层架空方式以单面架空为最佳；随室外风速的增加，室外环境对天井内温度的影响减弱。

Abstract：
With a multi-story office building in Sanya as the object, studies the influence of the main structural characteristics, bottom overhead model and outdoor environment of the courtyard on the ventilation effect by simulation. The results show that when the length-width ratio is 1∶1, the optimum courtyard depth-width ratio is between 4∶1 and 5∶1, the optimum bottom overhead is unilateral, and the influence of outdoor environment on the temperature within courtyard is weakened with the increase of outdoor air velocity.
