如何区分正压送风机和消防排烟风机

 

记得以前汇弘小编和大家说过,风机大体被分为两大类,一种是离心风机,而另一种是轴流风机。但按照功能再细制划分的话,还会分出很多,比如消防排烟风机、正压送风风机、厨房排油烟风机、除尘风机、高压风机、锅炉引风机等等,而今天小编要和大家说的是正压送风风机和消防排烟风机应该如何区分,我们在选择风机的时候,如何分清楚应该选择的是正压送风风机还是消防排烟风机,下面汇弘小编就详细的来和大家讲解一下。

1、定义区别:

  正压送风机主要是一种可以将空气从外面吹到里面的风机。一般室内压力高于室外压力,普通风机无法将空气从室外送入室内,因此在建筑现场,风机是室内通风的主要设备。此外,送风机还用于向避难建筑供气。一旦发生火灾,会产生大量的烟雾、一氧化碳等有毒气体,遮挡视线,通过风机将空气吹入方舱消防楼梯,使室内烟雾无法到达楼梯,为人们创造避难条件。

  消防排烟风机是指适用于“高层建筑、地下建筑、隧道及公共场所”等,可用于通风和高温排烟的风机。另外,根据消防要求,消防风机要在280°等高温条件下连续工作30分钟以上,即使连续工作20小时也不会损坏。平均温度为100°C 时的时间。

  2、功能区别:

  在防烟排烟系统中,送风机常用于防烟系统,主要用于对建筑物内部进行加压送风。通常,它可以对建筑物内部的空气进行加压,以保证建筑物内的空气流通。发生火灾时,室外的新鲜空气也可以通过送风管道吹入楼梯间,使烟雾和有毒气体不扩散到消防管道,使人员及时逃生。

  在排烟和防烟系统中,消防排烟风机一般用于排烟系统。当发生火灾时,消防风机可以在有效时间内将建筑物内的烟雾和有毒气体排除,使人员能够顺利逃生。

  3、安装位置不同

  正压风机主要用于防烟系统,安装在通风管道内。它通常与防火阀组合使用,形成防烟系统。

  消防排烟风机主要用于排风系统,安装在排风管道内。排烟器和排烟通常相互组合使用,组成一个排烟系统。

  以上就是正压送风机消防排烟风机的区别。两者在使用过程中区别并不明显,主要是功能和安装场所有些区别,主要功能是排烟。所以在使用安装过程中分清哪根管道是送风系统,哪根管道是排烟系统,这样就会很清晰的分辨出哪里应该安装正压送风风机,哪里应该安装排烟风机了。
