| 摘 要： | 本文以一超市建筑为例，运用火灾模拟软件FDS对排烟口位置、排烟口数量、排烟量、排烟口面积等对机械排烟效果的影响进行了研究。研究表明顶棚排烟优于侧壁排烟；排烟口应尽量远离疏散出口；排烟量达到一定数值之后，再增加排烟量，对排烟效果影响不大；增加排烟口数量，并合理分布其位置，可以得到良好的排烟效果。

| Abstract: | Taking a supermarket architecture as an example,the influence on mechanical exhaust effect by the smoke vent location,the amount of smoke vent,smoke exhaust rate,smoke vent area were studied with fire simulation software FDS. The results showed that the roof is superior to wall exhaust smoke; and smoke vent should be far from escape exits as possible; and after the smoke exhaust rate reaches a certain value,there is only little effect on the exhaust effect can be obtained by increasing smoke exhaust rate; a... |
