当楼宇住宅火灾发生时，人员走向是:室内→走廊→前室→楼梯间。当量较大时，电梯前室和楼梯间的防火门会出现同时开启的情况，这时要求正压送风的流向是:楼梯间→前室→走廊，这样才能起到防烟的效果。

压力传感器根据其传感器结构，分为机械式压力传感器和电子式压力传感器。当楼宇住宅火灾发生时，人员走向是:室内→走廊→前室→楼梯间。当量较大时，电梯前室和楼梯间的防火门会出现同时开启的情况，这时要求正压送风的流向是:楼梯间→前室→走廊，这样才能起到防烟的效果。

智能建筑余压监控系统的整个目的就是保持楼梯间和前室的余压值维持在范围，阻挡有害烟气进入的同时，确保防火门的正常开启，保证生命通道的畅通。也叫余压测控系统、压差测控系统、或智能余压监控系统，是高层建筑的正压送风系统中一个调节消防前室或楼梯间余压值的一套系统性装置。本系统含余压监控系统主机、余压探测器 、余压控制器和泄压阀及旁通阀执行机构控制模块。

When the supply air volume and time of itive pressure air supply system is out of control, the normal escape route may be too high because of the itive pressure of the front room, the fire door can not open the serious cequences. In view of the above ciderati, the Sichuan Institute of Fire Science combined with experience to provide data of residual pressure value. By controlling the opening and closing of the by-pass Valve, the differential control system can effectively control the residual pressure of the mechanical pressurized air supply system within the reasonable range required by the national standard ——40-50 PA in the smoke-proof Stairwell, the front room, the shared front room, the front room of the fire elevator room and the enclosed refuge floor (room) are 25-30Pa.
