自然排烟设计中应注意的问题

The Problems with the Natural Smoke Ventilation Design

自然排烟作为一种投资低廉、技术依赖性弱的防排烟方式在工程实践中被广泛采用,但在自然排烟的设计和施工中出现了许多不能真正实现防排烟功能的问题。从自然排烟口位置的设置、开启方式及自然排烟口面积的设计三个方面对自然排烟设计工程实践中存在的问题及改进的方法进行了探索性分析,为自然排烟设计提供了依据。

Natural smoke ventilation is a cheap and non -technology dependent smoke ventilation method in engineering practice. However, this method encounters some problems with smoke ventilation. This paper explores these problems in terms of the position of the smoke ventilation mouth, the opening of the smoke ventilation mouth and the area of the smoke ventilation.
