廚房排煙工程的安裝是一個(gè)很細(xì)致的工作，有的時(shí)候處理不好，就可能有噪音發(fā)出，所以在進(jìn)行廚房排煙工程安裝的時(shí)候一定要做好靜音處理，那廚房排煙工程的靜音工作應(yīng)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(fēng)工程對于工廠、倉庫、飯店等都是需要準(zhǔn)備的設(shè)備，通風(fēng)工程主要負(fù)責(zé)通風(fēng)、引風(fēng)、排風(fēng)、除塵等工作，濟(jì)南酒店廚房排煙罩平?？吹降娘L(fēng)扇、空調(diào)其實(shí)都是通風(fēng)工程的一種。那么像一般在工廠、燒烤店等安裝的通風(fēng)裝置是利用風(fēng)管，因此在通風(fēng)工程的施工之前要做好準(zhǔn)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.
