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(duì)于新建商業(yè)綜合體其餐飲業(yè)態(tài)排油煙系統(tǒng)的設(shè)計(jì)，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(duì)應(yīng)”獨(dú)立系統(tǒng)型

"One-to-one correspondence" independent system type

所謂“一一對(duì)應(yīng)”型即一個(gè)餐飲廚房對(duì)應(yīng)一個(gè)管井及一套排油煙與油煙凈化系統(tǒng)，設(shè)備由客戶方自行根據(jù)需求二次設(shè)計(jì)安裝，開發(fā)商僅預(yù)留管道位置即可，此方式在獨(dú)立的餐飲區(qū)域或者在集中管井內(nèi)設(shè)置每戶獨(dú)立的立管可實(shí)現(xiàn)。

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(duì)一”集中系統(tǒng)型

"Many-to-one" centralized system type

所謂“多對(duì)一”型即多個(gè)廚房對(duì)應(yīng)一個(gè)集中管井，集中系統(tǒng)型其實(shí)可以分為：用戶廚房?jī)?nèi)設(shè)置、開發(fā)商設(shè)置、用戶和開發(fā)商共同設(shè)置的三種形式，這個(gè)在前期設(shè)計(jì)中就已經(jīng)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(nèi)襯不銹鋼鐵皮風(fēng)管；住宅廚房成品排氣道尺寸，依據(jù)層數(shù)、層高查取；土建排油煙道，需要知道每戶排油煙罩的風(fēng)量和同一個(gè)煙囪負(fù)擔(dān)戶數(shù)的同時(shí)開啟率，從而來計(jì)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(duì)于200m及以上（或150m及以上)的公寓樓，排油煙需要轉(zhuǎn)換核心筒上塔樓頂排放，150m及以上的樓層，廚房煙囪不轉(zhuǎn)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(zhuǎn)換豎井和水平干管的尺寸計(jì)算，采用成品廚房排氣道，風(fēng)管的面積可以等于所負(fù)擔(dān)的豎向煙道的面積之和；采用土建煙道，風(fēng)管按照所服務(wù)總的戶數(shù)，根據(jù)每戶排油煙罩風(fēng)量，同時(shí)開啟率，來計(jì)算排油煙量，根據(jù)風(fēng)管風(fēng)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.
