The result shows that the setting up of the flue outlet reduces the distance of people fleeing. But under this condition the fire smoke density inside and outside of the two flue outlet will increase. The exhaust velocity designed at smoking outlet can accelerate the move of the smoke, and makes the fire smoke density outside of the flue outlet reduced greatly. This situation will offer an relatively safe space for people fleeing, and fire rescuing can also be carried out from two directions.
结果表明：烟道的设置降低了人员逃生的相对长度，但使得位于火源点2端烟道口内外侧的隧道顶部烟气浓度均有所增高；烟道口处设有一定的排风时，可加速烟气进入烟道从而排出的速度，使得2端烟道口外侧的烟气浓度和温度大大降低，提高了人员逃生的安全系数，也使得火灾发生时消防人员可从上、下游两个方向对火灾进行扑救。
No matter what kind of pressurization systems are used, the situation that building exit door, stair door and vestibule door on first floor open at the same time should be avoided, because on one hand it is difficult to ensure the air velocity at the door opening on the fire floor, on the other hand the pressure difference on other closed evacuation door drops greatly, which may lead to failure of system.
不论何种形式的加压送风系统，人员疏散时应尽量避免建筑外门、首层楼梯间门和前室门三道门同时开启，因为此时一方面难以保证着火层开启门洞的风速，另一方面其它关闭的疏散通道门上的作用压差也大幅下降，可能直接导致加压系统失效。
