地暖采暖空间中庭火灾烟气流动规律探究

在理论研究采用地暖采暖空间的垂直温度场分布规律的基础上,对此类环境火灾情况下烟气蔓延和流动规律进行小尺寸试验,并进行数据分析。通过对比分析得到烟气在地暖采暖空间中庭下降速度要比普通的均匀无采暖环境迅速。为此类环境的防烟设计提供理论依据。

On the Pattern of the Fire Smoke Movement in large Space Heated by Floor Heating

The construction scale of the current commercial complex in a new city shows a tendency of booming development. This paper makes a study of the fire smoke pattern of large space of the vertical distribution of temperature with a floor heating system. A pilot test is done about the movement of the fire smoke and the pattern of this movement. The result shows that the descending movement of the smoke in the space heated by floor heating system is faster than that of the smoke in the space without this heating system.
