专注通风管道加工·排烟罩

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.

对于新建商业综合体其餐饮业态排油烟系统的设计，可归纳为以下两大类的多种方式：

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:

“一一对应”独立系统型

"One-to-one correspondence" independent system type

所谓“一一对应”型即一个餐饮厨房对应一个管井及一套排油烟与油烟净化系统，设备由客户方自行根据需求二次设计安装，开发商仅预留管道位置即可，此方式在独立的餐饮区域或者在集中管井内设置每户独立的立管可实现。

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.

“多对一”集中系统型

"Many-to-one" centralized system type

所谓“多对一”型即多个厨房对应一个集中管井，集中系统型其实可以分为：用户厨房内设置、开发商设置、用户和开发商共同设置的三种形式，这个在前期设计中就已经确定。

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.

高层建筑厨房烟囱的类型主要有住宅厨房成品排气道和土建排油烟道，内衬不锈钢铁皮风管；住宅厨房成品排气道尺寸，依据层数、层高查取；土建排油烟道，需要知道每户排油烟罩的风量和同一个烟囱负担户数的同时开启率，从而来计算排油烟道的尺寸。

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.

厨房排油烟需要高空排放，对于200m及以上（或150m及以上)的公寓楼，排油烟需要转换核心筒上塔楼顶排放，150m及以上的楼层，厨房烟囱不转换直接出屋面排放。

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.

排油烟转换竖井和水平干管的尺寸计算，采用成品厨房排气道，风管的面积可以等于所负担的竖向烟道的面积之和；采用土建烟道，风管按照所服务总的户数，根据每户排油烟罩风量，同时开启率，来计算排油烟量，根据风管风速，来求取汇总管的尺寸。

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.
