空气是人们生活中最重要的，缺少了空气人们就会感到窒息活不下去，空气中的氧气也是维持人生命最基本的要素，所以要时刻保持着室内的通风，满足人们对于氧气的需求，这也是通风管道对于人们生活的作用。在人群密集或者相对于封闭的空间中空气的不流通、呼出的二氧化碳等等都会使得空气不流通，所以要时刻记得通风，尤其是在工厂中更要注意。
Air is the most important thing in people's life. Without air, people will feel suffocated and unable to live. Oxygen in the air is also the most basic element to maintain human life. Therefore, it is necessary to keep indoor ventilation to meet people's demand for oxygen, which is also the role of ventilation duct in people's life. In crowded or closed space, the air is not in circulation, exhaled carbon dioxide and so on, so always remember to ventilate, especially in the factory.
通风管道的使用可以使得良好的通风，促进室内的空气流通，控制气流的速度缓解窒息感，什么叫做通风，也就是将室内或者是封闭空间里的污浊的空气排出去，在工厂中将产生的有害物质都经过净化处理之后都排出室外，然后再将新鲜空气送入室内，稀释空气的有害物质，满足人们对于空气的需求。
The use of ventilation duct can make good ventilation, promote indoor air circulation, control the speed of airflow and relieve suffocation. What is called ventilation, that is, the dirty air in the room or in the enclosed space is discharged out, and the harmful substances produced in the factory are discharged outdoor after purification treatment, and then the fresh air is sent into the room to dilute the air Harmful substances, to meet people's demand for air.
还有一点就是通风管道保持空气的流通，让人们能够呼吸到新鲜的空气，这也是为人们的身体着想，通风管道在楼房建筑中都有着广泛的应用，让室内的空气更加的畅通。
There is also a point is that the ventilation duct to maintain the air circulation, so that people can breathe fresh air, which is also for the sake of people's body, ventilation ducts in buildings and buildings have a wide range of applications, so that indoor air more smooth.
