廚房排煙工程的安裝是一個很細致的工作，有的時候處理不好，就可能有噪音發出，所以在進行廚房排煙工程安裝的時候一定要做好靜音處理，那廚房排煙工程的靜音工作應該怎么做好呢，
The installation of kitchen smoke exhaust engineering is a very detailed work. Sometimes, if it is not handled properly, there may be noise. Therefore, when installing the kitchen smoke exhaust project, we must do a good job of mute treatment. How should we do a good job in the silent work of kitchen smoke exhaust engineering,
通風工程對于工廠、倉庫、飯店等都是需要準備的設備，通風工程主要負責通風、引風、排風、除塵等工作，濟南酒店廚房排煙罩平常看到的風扇、空調其實都是通風工程的一種。那么像一般在工廠、燒烤店等安裝的通風裝置是利用風管，因此在通風工程的施工之前要做好準備工作，一起來了解一下吧。
Ventilation engineering is the equipment that needs to be prepared for factories, warehouses, hotels, etc. the ventilation engineering is mainly responsible for ventilation, induced air, exhaust, dust removal and other work. The fan and air conditioning commonly seen in the kitchen exhaust hood of Jinan hotel are actually one kind of ventilation engineering. Well, the ventilation devices installed in factories, barbecue shops, etc. generally use air pipes. Therefore, we should make preparations before the construction of ventilation engineering. Let's have a look at it.
