YALICHUANGANWI正压送风系统的送风口出风可使楼梯间及消防电梯前室形成正压,阻挡有害烟气进入人的疏散通道。但是当正压送风系统送风量及送风时间不可控时,正常的逃生路线有可能会因为前室正压过大,防火门无法开启的严重后果。鉴于上述考虑,部四川消防科学研究所结合国际经验提出余压值的数据。建筑发生火灾时,防烟楼梯间、避难走道及其消防前室,是人员撤离的生命通道和消防人员进行扑救的通行走道

压力控制系统可通过控制旁通阀的开闭,将机械加压送风系统的压力值有效控制在要求的合理范围内-----防烟楼梯间40-50Pa,前室、合用前室、消防电梯间前室、封闭避难层(间)为25-30Pa。The pressure control system can effectively control the pressure value of the mechanical pressurization air supply system within the reasonable range required by the national standard-40-50 PA in the smoke-proof Stairwell by controlling the opening and closing of the by-pass Valve, the front room, the shared front room, the front room of the fire elevator room and the enclosed refuge floor (room) are 25-30Pa.

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.
