电气上是否能控制不同防烟分区的风口关闭?当火灾呗确认后,应能开启排烟区域的排烟口和排烟风机,并自动关闭与排烟无关的通风、空调系统。

Whether can the electrical control different smoke preventing zoning tuyere close? When the fire Bai confirmation, should be able to open the exhaust area of the exhaust port and the exhaust fan, and automatically shut down ventilation, air conditioning system and smoke exhaust independent.

1、多个排烟分区合用排烟排风系统,排烟管道安装的就是电动阀+排烟风口,平时常开排风,着火关闭非着火点排烟分区的设置在支管上的电动阀,超过280度风口熔断关闭,烟气如扩散到其他防烟分区则开启此防烟分区支管上的电动阀。

1, a plurality of smoke control zones combined with smoke exhaust system, smoke exhaust pipe installation is electric valve + smoke outlet, usually open exhaust fan, fire electric valve non ignition smoke control zones set off on the branch pipe, more than 280 degrees air blown off, flue gas such as spread to other smoke preventing zoning is to open the anti electric smoke zoning branch pipe on the valve.

2、一般住宅的地下室为储藏功能,并划分为小的储藏间,排烟排风系统合用,一套系统也就负责1个或者2个防烟分区,并且烟气扩散很快。

2, the general residential basement for storage function, and is divided into small storeroom, smoke exhaust system combination, a set of system is also responsible for 1 or 2 smoke preventing zoning, and smoke spread quickly.

其实,阀门来回开启与关闭,通风设备厂家认为这样反而降低了系统的安全性,所以采用全部敞开的排烟风口比较好,平时常开排风,着火也全部开启,超过280度关闭。

In fact, the valve to open and close the back and forth, ventilation equipment manufacturers think that it reduces the system security, so using the smoke exhaust all open the better, usually open ventilation, fire are all open, more than 280 degrees off.济南油烟净化
