Because of the existence of catering stores, the cooperation of mechanical and electrical disciplines is also required: the planning of air conditioning and ventilation, especially the purification and emission of lampblack, and the scheme of lampblack exhaust system are not only related to the quality of lampblack exhaust in the kitchen of catering industry, the air quality of outdoor sensitive areas, but also affect the commercial internal environment and grade.

對于新建商業綜合體其餐飲業態排油煙系統的設計，可歸納為以下兩大類的多種方式：

For the design of the oil smoke exhaust system of the catering industry in the new commercial complex, it can be summarized into the following two categories:

“一一對應”獨立系統型

"One-to-one correspondence" independent system type

所謂“一一對應”型即一個餐飲廚房對應一個管井及一套排油煙與油煙凈化系統，設備由客戶方自行根據需求二次設計安裝，開發商僅預留管道位置即可，此方式在獨立的餐飲區域或者在集中管井內設置每戶獨立的立管可實現。

The so-called "one-to-one correspondence" type means that a catering kitchen corresponds to a tube well and a set of oil fume and oil fume purification system. The equipment is designed and installed by the customer according to the requirements for the second time. The developer can only reserve the position of the pipeline. This method can be achieved by setting an independent riser for each household in the independent catering area or in the centralized tube well.

“多對一”集中系統型

"Many-to-one" centralized system type

所謂“多對一”型即多個廚房對應一個集中管井，集中系統型其實可以分為：用戶廚房內設置、開發商設置、用戶和開發商共同設置的三種形式，這個在前期設計中就已經確定。

The so-called "many-to-one" type means that multiple kitchens correspond to a centralized tube well. The centralized system type can be divided into three types: user kitchen settings, developer settings, and user and developer settings, which have been determined in the preliminary design.

高層建筑廚房煙囪的類型主要有住宅廚房成品排氣道和土建排油煙道，內襯不銹鋼鐵皮風管；住宅廚房成品排氣道尺寸，依據層數、層高查??；土建排油煙道，需要知道每戶排油煙罩的風量和同一個煙囪負擔戶數的同時開啟率，從而來計算排油煙道的尺寸。

The types of kitchen chimneys in high-rise buildings mainly include finished exhaust ducts in residential kitchens and oil exhaust ducts in civil works, lined with stainless steel sheet iron air ducts; The size of finished exhaust duct of residential kitchen shall be checked according to the number of floors and the height of floors; For the civil oil exhaust flue, it is necessary to know the air volume of each oil exhaust hood and the simultaneous opening rate of the same chimney bearing the number of households, so as to calculate the size of the oil exhaust flue.

廚房排油煙需要高空排放，對于200m及以上（或150m及以上)的公寓樓，排油煙需要轉換核心筒上塔樓頂排放，150m及以上的樓層，廚房煙囪不轉換直接出屋面排放。

The kitchen oil fume needs to be discharged from high altitude. For apartment buildings of 200m and above (or 150m and above), the oil fume needs to be transferred to the core tube and discharged from the top of the tower. For floors of 150m and above, the kitchen chimney is not converted and discharged directly from the roof.

排油煙轉換豎井和水平干管的尺寸計算，采用成品廚房排氣道，風管的面積可以等于所負擔的豎向煙道的面積之和；采用土建煙道，風管按照所服務總的戶數，根據每戶排油煙罩風量，同時開啟率，來計算排油煙量，根據風管風速，來求取匯總管的尺寸。

For the size calculation of oil fume conversion shaft and horizontal main pipe, the finished kitchen exhaust duct is adopted, and the area of the air duct can be equal to the sum of the area of the vertical flue; The civil flue is adopted, and the air duct is calculated according to the total number of households served, the air volume of the fume hood of each household, and the opening rate at the same time, and the size of the header is calculated according to the wind speed of the air duct.
