【摘要】 根据中庭建筑的特点,提出中庭建筑“回廊+中庭顶部”的排烟方案。基于此方案,运用区域模拟思想,分析了回廊排烟条件下中庭建筑内烟气运动过程,建立了回廊溢出烟气质量卷吸流量的简化模型,推导了有／无回廊排烟条件下中庭排烟量的相互关系公式,从理论上说明了方案是可行的,并进一步通过模拟实验进行了验证。更多还原

【Abstract】 A new method of venting in both cloister and ceiling of atrium was proposed to control the smoke in atrium. The smoke movement under cloister venting was analyzed by a zone model. An empirical equation was deduced to calculate the entrainment rate of smoke spilling out of the cloister. Based on the equation and a series of experiments, the exhaust rates required to control the smoke under different venting methods were discussed.更多还原
