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.

所以安裝通風設備很有必要。那么在酒店安裝通風工程的安裝準備是怎樣的呢？

So it is necessary to install ventilation equipment. So what is the preparation for the installation of ventilation works in the hotel?

部件安裝前應進行如下檢查，經檢查合格并填寫有關驗收資料后方可進行安裝。

Before the installation of components, the following inspection shall be carried out, and the installation can only be carried out after passing the inspection and filling in the relevant acceptance data.

1、風口表面應平整。

 The surface of air outlet shall be flat.

2、風口各轉動部分應靈活，葉片或插板應平直，葉片內距應均勻，散流器的擴數環和調節應同軸，軸向間距分布勻稱，葉片等啟閉應完全，人防密閉閥方向與沖擊波相準確，不可裝反，葉片全開或全閉，不可作調節風量之用。

The rotating parts of the tuyere shall be flexible, the blade or insert plate shall be straight, the internal distance of the blade shall be uniform, the expansion ring and adjustment of the diffuser shall be coaxial, the axial spacing shall be evenly distributed, the opening and closing of the blade shall be complete, the direction of the air defense airtight valve shall be accurate with the shock wave, and it shall not be installed reversely, the blade shall be fully open or fully closed, and it shall not be used for adjusting the air volume.

3、各類閥門制作應牢固，調節制動裝置應準確靈活、可靠，并標明閥門啟閉方向，材料選用應符合規范要求。

All kinds of valves shall be made firmly, the adjustment and braking device shall be accurate, flexible and reliable, and the opening and closing direction of the valve shall be indicated, and the material selection shall meet the specification requirements.

很多空調還需要靠通風管道來通風，管道里邊陰暗潮濕，沒有光，特別容易滋生細菌，比如軍團菌?？照{還有個玻璃網，時間長了會沉積很多灰塵，這些灰塵會造成室內可吸入顆粒物的增多，它比灰塵小得多，直徑在10微米以下，能攜帶很多細菌微生物，還有化學物質，進入人體。

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.

濟南通風管道提醒您想要解決以上問題，就需要給酒店安裝通風管道設備，保障酒店內良好的空氣質量。

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