某建筑中庭自然通风效果测定与评价

The Study & Evaluation on Natural Ventilation in an Atrium-style Building

以上海一幢具有高大中庭的建筑为研究对象,通过实测,研究了供冷日和非供冷日、通风天窗开启与关闭时对中庭内温度分布的影响,同时实测了中庭自然通风能力。结果表明,通风天窗开启可使中庭室内顶部与室外温差比天窗关闭时降低达4℃以上。通风天窗开启时,自然通风量达到1万m3/h以上,通风效果良好。

Taking an atrium-style building of shanghai as a research object, tested the temperature distribution in the atrium while opening or closing the ventilation skylights in cooling and non-cooling day and tested the natural ventilation capacity as well. The results show that when the ventilation skylights open, the temperature difference between the top of the atrium and outdoor is more than 4℃ lower than that when the ventilation skylights close. Meanwhile, the natural ventilation can reach more than 10,000 m3/h resulting a good ventilation.
