现在的地下室空间利用的非常广泛,像是地下停车场、地下购物商场等等,看似节省了地上的空间,但是随之而来的还有安全问题,所以地下室通风管道也逐渐得到了重视!如何控制地下室排风排烟共用风口?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。
Now the basement space is very wide, like underground parking, underground shopping mall and so on, it seems to save the space on the ground, but the following security problems, so the underground ventilation pipe has gradually been paid attention to! How to control the common air vent of the ventilation and exhaust in the basement? Can we control the outlet closure of different smoke prevention zones? When the fire is confirmed, it should be able to open smoke outlets and smoke exhausting fans in the smoke extraction area, and automatically close the ventilation and air conditioning systems which are not related to the smoke exhaust.
如果是多个排烟分区合用的一个排烟系统呢,最好的解决的方法就是利用电动阀和排烟风口相结合,平时的时候呢也是需要经常开着排风的,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,阀门来回开启与关闭,个人认为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。

If it is a smoke exhaust system, the best way to solve it is to combine the electric valve and the exhaust air vent. In the ordinary time, it is also necessary to open the exhaust air regularly. The electric valve set on the branch pipe is closed by the fire. The fume of more than 280 degrees is closed and the flue gas is closed. If it is spread to other smoke prevention areas, the basement of the electric valve general residence on this smoke control section is opened for storage function, and it is divided into small storage room, the smoke exhaust system is used together, a system is also responsible for 1 or 2 smoke prevention areas, and the gas diffusion is very fast, the valve is opened and closed back and forth, personally think counter It reduces the safety of the system, so it is better to use all open smoke outlets, and usually open the exhaust regularly, and the fire is all opened, closing at more than 280 degrees.
地下室通风管道包括通气,如送鲜风和排气,这个范围很广,如工厂车间,生产场地空气,由于有害气体产生需要排出室外,又需要把室外空气输送至室内。这时就要使用流量大而压力小的空气输送管道,螺旋风管就最适用,一般情况下使用镀锌铁管,有腐蚀性及特别潮湿场所使用不锈钢管。送冷风。最常见的是中央空调的管道,这种管道需要加保温材料。螺旋风管可内贴保温材料,外表看来美观
The ventilation pipes of the basement include ventilation, such as the fresh air and the exhaust. This is a wide range, such as the factory workshop, the production of the air, because of the harmful gas production needs to be discharged outside, and the need to transport the outdoor air to the room. At this time, the use of large flow and pressure small air transportation pipeline, the spiral pipe is the most suitable, in general, the use of galvanized iron pipe, corrosive and special wet places to use stainless steel pipe. Send a cold wind. The most common is the central air conditioning pipeline, this pipeline needs to add the thermal insulation material. The spiral air duct can be attached to thermal insulation material and looks beautiful.
