消防排烟风机空间排烟量最基本要求
The most basic requirements of smoke exhaust volume in the space of fire smoke exhaust fan.

消防排烟风机是高层建筑排烟通风的重要设备，发挥着非常大的作用。随着应用的增多市场上也出现了各种型号的风机，但是由于消防排烟风机的特殊作用，其性能要求是相同的，消防排烟风机的空间排烟量需要满足以下要求，才能够发挥其高效作用。
Fire smoke exhaust fan is an important equipment of smoke exhaust and ventilation in high-rise buildings, which plays a very important role. With the increase of application, there are various types of fans in the market. However, due to the special role of fire smoke exhaust fan, its performance requirements are the same. The space smoke exhaust volume of fire smoke exhaust fan needs to meet the following requirements to play its efficient role.



一个防烟分区排烟或净空高度大于6.0m的不划防烟分区的房间时，应按每平方米面积不少于60m3/h计算（单台风机最小排烟量应不少于7200m3/h)。
For a smoke control zone or a room without smoke control zone whose clearance height is greater than 6.0m, the calculation shall be based on an area of not less than 60m3 / h per square meter (the minimum smoke exhaust volume of a single fan shall not be less than 7200m3 / h).

两个或两个以上防烟分区排烟时，应按最大防烟分区面积每平方米不少于120m3/h计算。中庭体积少于17000时，其排烟量按其体积的6次/h换气计算；中庭体积大于17000时，其排烟量按其体积的4次/h换气计算；但最小排烟量不应小于102000m3/h。
When smoke is discharged from two or more smoke control zones, the maximum smoke control zone area per square meter shall not be less than 120m3 / h. When the volume of atrium is less than 17000, the smoke exhaust volume shall be calculated as per 6 times / h of its volume; when the volume of atrium is greater than 17000, the smoke exhaust volume shall be calculated as per 4 times / h of its volume; however, the minimum smoke exhaust volume shall not be less than 102000m3 / h.



高层建筑防烟楼梯间及其前室、消防电梯间前室或合用前室，当裙房以上部位利用可开启外窗进行自然排烟，裙房部分不具备自然排烟条件时，其前室或合用前室应设置局部机械排烟设施，其排烟量按前室每平方米不少于60m3/h计算。
In the smoke-proof staircase and its front room, the front room of fire elevator room or shared front room of high-rise building, when the part above the podium uses the openable external window for natural smoke exhaust, and the part of the podium does not have the conditions for natural smoke exhaust, the front room or shared front room shall be equipped with local mechanical smoke exhaust facilities, and the smoke emission shall be calculated as per the front room of not less than 60m3 / h per square meter.

以上就是目前消防排烟风机应用比较多的领域的排烟量基本要求，只有满足以上要求，消防排烟风机才能算是合格的设备，才能够发挥其自身的性能优势。
The above is the basic requirements of smoke exhaust volume in the field of fire smoke exhaust fan application. Only if the above requirements are met, the fire smoke exhaust fan can be regarded as qualified equipment, and can play its own performance advantages.



果我哋喺应用过程中发现救火排烟风机嘅流量过大，唔符合使用要求或者系短时间内要较小嘅流量，我哋可以利用节流装置进行较。喺救火排烟风机嘅车、泊车或者运转过程中，如发现唔正常现象时，应即刻进行检查。对寒暑表同油标嘅灵敏性定期检查，并且应该控制轴承箱油位喺规定嘅允许裏面食.次次拆修后救火排烟风机应更换机油之外，重应定期更换机油。对E式传动嘅轴承座应定期（季度）检查，清洗同补加机油，以防轴承烧坏。
