加压送风量与门两侧压差值关系的网络模拟分析
Network simulation for relationship of pressurized supply air rate and pressure difference across the door
摘要：
利用多区域网络模型，以20层高层建筑为例，分别对各种加压方式下的加压送风量与门两侧压差值的关系进行了定量模拟分析。模拟结果表明，加压送风量的大小对门两侧压差值特别是着火层门两侧的压差值具有决定性的影响。

Abstract：
Taking a twenty storied highrise building for example, uses a multizone network model to simulate the relationship of the pressurized supply air rate and the pressure difference across the door under various pressurized conditions, providing a quantitative analysis method of evaluating the availability of the smoke control system. The result shows that the pressurized supply air rate has a significant effect on the pressure difference across the door especially the door in the fire floor.
