风机盘管的工作原理
2025-07-19
机组内不断地再循环所在房间或室外的空气,使空气通过冷水(热水)盘管后被冷却(加热),以保持房间温度的恒定。在制冷模式下,由入水口进入冷水,冷水通过盘管循环,电动机带动风扇运转,空气进入与盘管中的冷水发生热交换被降温

设置防火阀及排烟阀的要求?
2025-07-19
防火阀用在通风、空调系统的送、回风管路上,平时呈开启状态,当火灾一旦发生,管道内气体温度(temperature)达到70℃时即自行关闭,并在一定时间内能满足耐火稳定(解释:稳固安定;没有变动)性和耐火完整性要求,起隔烟阻火作用。

防火调节阀的作用
2025-07-19
防火调节阀(使用材料:铸铁、铸钢、不锈钢等)不需做报警联动控制,但必需设监视模块,使阀门能受主机监视,当阀门熔断器动作后,防火阀输出信号到监视模块,模块再输出信号到报警主机,这样可以使控制中心监视到空调系统防火阀的动作情况(Condition)。
