某超高中庭机械排烟消防设计优化分析

Optimization analysis of the mechanical smoke exhaust design of a super-high atrium

分析传统高层建筑中庭排烟系统设计中存在的问题。以某高层建筑为例,介绍其超高中庭的防烟分区和中庭烟气控制策略,对其烟气流动情况进行模拟分析,计算该项目中庭在各设定火灾场景下可提供的安全疏散时间,论证其排烟系统有效性,提出相应的优化策略和具体措施。

Problems of traditional higb-rise building atrium smoke exhausting system design were analyzed. Taking a high-rise building as an example, the smoke prevention zone and atrium smoke control strategy of the super-high atrium were introduced. The smoke movement was simulated, to calculate tbe safety evacuation time in each fire scene, demonstrate the effectiveness of the smoke exhausting system, and provide optimization strategy and specific measures.
