The ventilation pipe is often installed in the exhaust pipe of the kitchen, which is used to discharge oil smoke. However, the hotel also needs to install the ventilation pipe. Because the hotel is relatively closed, oxygen is relatively insufficient, but carbon dioxide may exceed the standard.

很多空调还需要靠通风管道来通风，管道里边阴暗潮湿，没有光，特别容易滋生细菌，比如军团菌。空调还有个玻璃网，时间长了会沉积很多灰尘，这些灰尘会造成室内可吸入颗粒物的增多，它比灰尘小得多，直径在10微米以下，能携带很多细菌微生物，还有化学物质，进入人体。

Many central air conditioners also need to rely on ventilation pipes to ventilate. The inside of the pipes is dark and humid, and there is no light. It is easy to breed bacteria, such as Legionella. The air conditioner also has a glass net, which will deposit a lot of dust after a long time. These dust will cause the increase of indoor inhalable particles. It is much smaller than the dust, with a diameter of less than 10 microns. It can carry a lot of bacteria, microorganisms, and chemicals into the human body.

济南通风管道提醒您想要以上问题，就需要给酒店安装通风管道设备，保障酒店内良好的空气质量。

In order to solve the above problems, it is necessary to install ventilation pipe equipment to ensure good air quality in the hotel.
