因为形状相似，很多人总是会把通风管道与排烟管道弄混，下面讲一下通风管道与排烟管道的区别:

排烟管道

　　1.作用不同

　　通风管道是专门送风以及排风的管道，目的是为了保持室内空气的畅通，起到交换空气的作用。而排烟管道是将房间内产生的烟雾排出去的，不需要送风，

　　2.用处的区别

　　风管在安装时要保证表面光滑洁净，安装在室外的风管还需要采取一定的措施以达到防寒防潮的目的。当风管伸入结构风道时，在末端应安上钢板网，防止系统运行时，外部杂物会因为机器产生的吸力跟着进入风管内，造成机器损坏。

　　虽然都是采用镀锌铁皮制作，排烟风管要求耐高温，对防火要求更高;建筑设计中，排烟风管的镀锌铁皮的厚度是按照高压的标准选用的，一般通风系统是按照中低压系统选用的;如果不是空调系统的风管，一般通风管道不需要保温，排烟风管如果是室内安装，一般要做隔热处理。

排烟管道

　　就管道讲本身都是管道，但从名称和作用上来说，就可以看出差别。通风起换气作用保持室内空气通畅，所以通风管道就是为房间或设备送风排风的管道。排烟管道是专门供烟气排放的管道。

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.
