乐清汽车组合开关:电动窗开关电动开窗机的一些小常识
作者:管理员    发布于:2015-10-27 15:16:38    文字:【】【】【


    乐清汽车组合开关,清电动窗开关电动开窗机的系统控制和自动控制目前有两种。温室控制系统是根据测得的温度,阳光照度,风的强度,湿度,下雨程度的数值,并与预先设定值相比较,来进行开窗和关窗控制的系统。

  自动排烟排热系统是国际化的新型的消防观念,如发生火警产生烟和热时,用于排烟排热的窗户会自动打开。由于现在的建筑对建筑材料的防火要求逐渐全面,并从阻燃性方面精确地界定材料的防火性能。如果一旦产生火灾,烟雾及其中所含的有害物质对人员产生更直接的伤害。或者说有害烟雾妨碍主动的救生行为和被动的逃生行为。

   从火灾的发展历史中的研究中可以看出,火灾发生的开始阶段,一开始会产生大量的烟雾和热能。烟雾由于热的作用而上升并聚集在建筑物的上层。
