  • 排煙管道和通風管道的區別

因為形狀相似,很多人總是會把通風管道與排煙管道弄混,下面講一下通風管道與排煙管道的區別:


排煙管道


  1.作用不同


  通風管道是專門送風以及排風的管道,目的是為了保持室內空氣的暢通,起到交換空氣的作用。而排煙管道是將房間內產生的煙霧排出去的,不需要送風,


  2.用處的區別


  風管在安裝時要保證表面光滑潔凈,安裝在室外的風管還需要采取一定的措施以達到防寒防潮的目的。當風管伸入結構風道時,在末端應安上鋼板網,防止系統運行時,外部雜物會因為機器產生的吸力跟著進入風管內,造成機器損壞。


  雖然都是采用鍍鋅鐵皮制作,排煙風管要求耐高溫,對防火要求更高;建筑設計中,排煙風管的鍍鋅鐵皮的厚度是按照高壓的標準選用的,一般通風系統是按照中低壓系統選用的;如果不是空調系統的風管,一般通風管道不需要保溫,排煙風管如果是室內安裝,一般要做隔熱處理。


排煙管道


  就管道講本身都是管道,但從名稱和作用上來說,就可以看出差別。通風起換氣作用保持室內空氣通暢,所以通風管道就是為房間或設備送風排風的管道。排煙管道是專門供煙氣排放的管道。


Because of their similar shape, many people confuse the ventilation duct with the smoke exhaust duct. Here's the difference between the ventilation duct and the smoke exhaust duct. The function is different, the ventilating duct is the specialized air supply and the exhaust duct, the goal is maintains the indoor air unobstructed, plays the exchange air the role. The smoke exhaust pipe is generated in the room to discharge the smoke, do not need to supply air, 2. Use of the difference, wind pipe in the installation to ensure smooth and clean surface, installed in the outdoor wind pipe also need to take certain measures to achieve the goal of cold and damp. When the air duct into the structure, the end should be installed with Steel Mesh, to prevent the system operation, external debris will be generated by the suction into the air duct, resulting in machine damage. Although they are all made of galvanized iron sheet, the smoke exhaust duct requires high temperature resistance and higher requirements for fire protection. In architectural design, the thickness of the galvanized iron sheet of the smoke exhaust duct is selected according to the high pressure standard General ventilation system is in accordance with the low-pressure system selected; if not air-conditioning system duct, general ventilation does not need heat preservation, smoke exhaust duct if indoor installation, general to do heat insulation treatment. Exhaust smoke pipe, on the pipe itself is a pipe, but from the name and function, you can see the difference. Ventilation plays the role of ventilation to keep the indoor air open, so the ventilation duct is for the room or equipment supply and exhaust air duct. Smoke exhaust pipe is a special pipe for smoke emission.
