义乌大剧院复杂中庭空间排烟设计分析

Design and analysis of smoke exhaust in complex atrium space of Yiwu Grand Theater

介绍了义乌大剧院公共前厅复杂的建筑空间及其内部防烟分区的划分。通过对该前厅的自然排烟和机械排烟方案进行计算和分析比较,确定了前厅的机械排烟方式和各防烟分区机械排烟量。利用火灾模拟软件对该前厅的烟气厚度等参数进行了模拟,验证了排烟设计方案的合理性。

The complex architectural space of the public front hall of the Yiwu Grand Theater and the division of its internal smoke-proof partitions are presented.Through the detailed calculation,analysis and comparison of natural smoke exhaust and mechanical smoke exhaust in the front hall,the mechanical smoke exhaust method of the front hall and the mechanical smoke exhaust volume of each smoke prevention zone are determined.Fire smoke simulation is carried out on the smoke thickness of the front hall by using fire simulation software,and the rationality of the smoke exhaust design scheme is verified.
