The wall of the kitchen smoke exhaust hood installation should have sufficient strength in terms of structure and materials. The external wall openings of smoke exhaust pipes and air ducts can be made by building prefabricated concrete blocks with holes or embedding steel pipes with holes. The installation method for insulation walls (preferably using hollow bricks) is the same as for normal walls. If the walls are not strong enough, they need to be reinforced with wooden boards or other materials.

厨房排烟罩安装的烟管直接穿过外墙至室外，应该在室外排气口设置防止污染环境和避风的构件。共用竖向烟道连接的吸油烟机，爱乐瑞酒店厨房排烟罩竖向烟道的断面应根据所负担的排气量计算确定。

The smoke pipe installed on the kitchen exhaust hood directly passes through the exterior wall to the outside, and components should be installed at the outdoor exhaust outlet to prevent environmental pollution and avoid wind. The section of the vertical flue of the kitchen smoke exhaust hood of the Aileri Hotel, which is connected by a shared vertical flue, should be calculated and determined based on the amount of exhaust it bears.

排烟是否通畅直接关系到厨房能否正常工作，油烟净化则只是厨房排烟系统中的一个净化空气的强制性功能。排烟系统和净化器的合理匹配是保证爱乐瑞油烟净化器净化效率的关键，同时也是油烟净化器设计人员容易忽略的问题，如果排烟系统设计不合理而造成整个厨房排烟不畅，济南厨房排烟则将无法安装油烟净化器，即使安装了油烟净化器也无法正常工作。

The smoothness of smoke exhaust directly affects the normal operation of the kitchen, while oil fume purification is only a mandatory function of purifying air in the kitchen smoke exhaust system. The reasonable matching of the smoke exhaust system and purifier is the key to ensuring the purification efficiency of the Ailerui oil fume purifier, and it is also a problem that designers of oil fume purifiers tend to overlook. If the smoke exhaust system design is not reasonable and causes poor smoke exhaust in the entire kitchen, Jinan kitchen smoke exhaust will not be able to install an oil fume purifier, even if an oil fume purifier is installed, it will not work properly.

由于在GB18483-2001中没有给出关于油烟排风收集系统与净化器匹配的计算依据，因而在实一般说欧式烟机的管道是在中间位置，而中士烟机的排烟管口却在烟机的一侧。这些情况影响着预留口的位置。

Due to the lack of calculation basis for matching the oil fume exhaust and collection system with the purifier in GB18483-2001, in practice, the pipeline of the European style smoke machine is generally in the middle position, while the exhaust pipe outlet of the sergeant smoke machine is on one side of the smoke machine. These situations affect the location of reserved openings.

厨房排烟即使安装了油烟净化器也无法正常工作。由于在中没有给出关于油烟排风收集系统与净化器匹配的计算依据，因而在实际进行油烟排风系统和净化器的设缺乏可靠实用的计算方法。掌握排烟系统的各部分特性及其对厨房整体排烟的影响，是进行油烟净化器选型和安装的前提，对于保证油烟净化器的正常工作具有非常重要的意义。

Even if an oil fume purifier is installed for kitchen smoke exhaust, it cannot function properly. Due to the lack of calculation basis for matching the oil fume exhaust and collection system with the purifier in, there is a lack of reliable and practical calculation methods for the design of the oil fume exhaust and purification system in practice.
