由于廚房所在建筑物的格局以及廚房在建筑物中位置不同，有條件的廚房應(yīng)由建筑物的集中空調(diào)系統(tǒng)進(jìn)行有序送風(fēng)。但目前所遇到的大部分情況是建筑物沒(méi)有設(shè)置廚房的送風(fēng)系統(tǒng)。許多帶餐廳、廚房等的建筑物，僅設(shè)計(jì)了集中采暖系統(tǒng)而無(wú)集中空調(diào)系統(tǒng)。當(dāng)廚房處于工作狀態(tài)時(shí)，排風(fēng)系統(tǒng)投入運(yùn)行，廚房?jī)?nèi)處于負(fù)壓狀態(tài)，新風(fēng)來(lái)源包括室外新風(fēng)滲透和餐廳的空氣大量補(bǔ)入廚房。

Due to the difference between the layout of the kitchen and the location of the kitchen in the building, conditioned kitchens should be ordered by the central air conditioning system of the building. But at present, most of the situation is that the building does not set the kitchen air supply system. Many buildings, such as restaurants, kitchens, etc., have only been designed for a centralized heating system without a centralized air conditioning system. When the kitchen is in working state, the exhaust system is put into operation, and the kitchen is in a negative pressure state. The fresh air source includes outdoor outdoor air infiltration and restaurant air filling into the kitchen.

無(wú)序送風(fēng)會(huì)造成廚房的工作環(huán)境惡劣。特別是在夏季，雖然餐廳內(nèi)通常會(huì)安裝一些局部柜式空調(diào)機(jī)以降低餐廳的室內(nèi)溫度，但室內(nèi)空氣補(bǔ)入廚房，并不能廚房的熱負(fù)荷并降低廚房溫度。由于廚房油煙較大，如果在廚房?jī)?nèi)設(shè)局部柜式空調(diào)機(jī)以降低廚房?jī)?nèi)的溫度，柜式空調(diào)機(jī)的回風(fēng)過(guò)濾則應(yīng)定期清理。

Disordered air supply will cause bad working environment in the kitchen. Especially in summer, although some local cabinet air conditioners are usually installed in restaurants to reduce the indoor temperature of restaurants, indoor air filling into the kitchen can not eliminate the heat load of the kitchen and reduce the temperature of the kitchen. If the kitchen fume is large, if the local cabinet air conditioner is installed in the kitchen to reduce the temperature in the kitchen, the return air filtration of the cabinet air conditioner should be cleaned regularly.

一般家里的油煙會(huì)先到副煙道里，做一個(gè)緩存，然后再通過(guò)隔板上的孔進(jìn)入主煙道，這樣可保證每戶的油煙是隔離開來(lái)的，不會(huì)串煙。主副煙道必須同時(shí)存在。一些業(yè)主家出現(xiàn)倒煙或是串煙現(xiàn)象很可能是由于裝修時(shí)錯(cuò)誤地把排煙管和主煙道相連，或是為了節(jié)省空間拆掉了副煙道。如果直接連接主煙道，由于其向上的吸力很大，可以比喻為“拔火罐效應(yīng)”，一旦氣壓比較低，就可能把別家的油煙壓到自家來(lái)。而副煙道則有很好的緩存作用，所以不能拆除。

Generally, the lampblack in the family will go to the auxiliary flue first, make a cache, then enter the main flue through the holes on the clapboard, so that each household's lampblack is isolated and does not smoke. The main and auxiliary flue must exist at the same time. Some owners smoke or smoke phenomenon is likely due to the decoration mistake of the exhaust pipe is connected with the main flue, or in order to save space down side flue. If the direct connection of the main flue, the upward suction is large, can be likened to the "cupping effect", once the pressure is relatively low, it may bring pressure to their home don't smoke here. And the auxiliary flue has a good caching effect, so it can't be dismantled.

廚房的排氣系統(tǒng)宜按防火分區(qū)劃分，盡量不穿過(guò)防火墻，穿過(guò)時(shí)應(yīng)裝防火閥。 廚房通風(fēng)系統(tǒng)的管道應(yīng)采用不燃燒材料制成。

The exhaust system of the kitchen should be divided according to the fireproof partition, and try not to pass through the firewall as far as possible, and the fire valve should be installed when passing through. The pipe of the kitchen ventilation system should be made of non - burning material.
