| 摘 要： | 本文在某高层安全核区域设计了一系列现场实验,通过送风系统和机械排烟的不同开启、关闭组合方式,定性判断送风与排烟的相互作用。结果显示：在送风量略大于排烟量的前提下,烟气层能够稳定在一定的高度,对人员的安全疏散是最有利的。因此,本文提出在满足楼梯间及其前室足够正压值的前提下,改造现有的送风系统,利用多余的正压值进行补气,以优化高层建筑内的防排烟效果。

| Abstract: | In this paper, some experiments were carried out to estimate the reciprocity between them in quality through the different operation manner including "opening" and "closing" in a high-rise building. It is shown that the layer heightcan maintain a constant when the air supply is just more than the smoke exhaust, which is advantaged to evacuation. Inthis paper, a new method is introduced that the altered pressurization system can be used to support the air supply whenthe pressurization in stairwell and its atria are enough. Thus, the smoke protection design is optimized. |
