厨房抽风排烟系统送风系统要计算清楚排风量，主要依据主厨房的尺寸、炉灶的数量、烟罩的大小规格、管道的长度和损耗，污染物的释放量来确定的；
The air supply system of the kitchen ventilation and smoke exhaust system should first calculate the exhaust air volume, which is mainly determined according to the size of the main kitchen, the number of stoves, the size and specification of the smoke hoods, the length and loss of the pipes, and the amount of pollutants released;
饮食业油烟排放标准要求每一炉灶需风量2000m3/h，即炉灶数量*2000就可以算出来。
The cooking fume emission standard of the catering industry requires that the air volume required by each stove is 2000m3/h, that is, the number of stoves * 2000 can be calculated.
若根据烟罩长度计算，可以按照2500m?/h计算就能算出厨房烟罩的排风量，当然还要考虑管道的长度，横截面积，弯头的数量，在设计初期尽可能的去匹配的风量稍微大一些。
If calculated according to the length of the hood, it can be calculated as 2500m/ H The exhaust air volume of the kitchen hood can be calculated through calculation. Of course, the length of the pipe, the cross-sectional area, and the number of elbows should also be considered. At the beginning of the design, the matching air volume should be slightly larger.
商用餐饮厨房抽排油烟通风系统设计原则和划分要与客户的投资方向、投资预算、能源效率、能源消耗、运行费用、生产流程等结合起来，更终确定一个更适合、科学、合理的方案。
The design principle and division of lampblack ventilation system for commercial catering kitchen should be combined with the customer's investment direction, investment budget, energy efficiency, energy consumption, operation cost, production process, etc., to finally determine the most suitable, scientific and reasonable scheme.
对于不同的功能间，如相互临近且使用时段相同的设备排风可以设计在同一系统里，以节省投资，节约能源。另外,局部通风和通风系统要分开设计和运行,避免炉灶没有工作而切配准备和卫生清理工作时也要运行局部通风的不经济使用情况。
For different function rooms, such as equipment exhaust close to each other and with the same use period, it can be designed in the same system to save investment and energy. In addition, the local ventilation and general ventilation systems shall be designed and operated separately to avoid the uneconomical use of local ventilation when the stove is not working and the preparation and cleaning work are also required.
商用厨房排油烟及补风设还要注意：商用厨房的功能、面积、通风要求、消防规定等；
In the design of smoke exhaust and air supplement for commercial kitchens, attention should also be paid to: the function, area, ventilation requirements, fire regulations, etc. of commercial kitchens;
在商业厨房规划中，通风是关重要的，既不能让厨房的气味跑到餐厅，又有必要保持厨房的空气流通，温度适宜，所以通风性是重要保证。
In the planning of commercial kitchen, ventilation is crucial. It is not only necessary to keep the smell of the kitchen away from the restaurant, but also necessary to keep the air circulation in the kitchen at a proper temperature. Therefore, ventilation is an important guarantee.
厨房排烟系统的构成厨房的排烟系统主要由集烟罩、排烟管道、油烟净化器、排烟风机(含消音器)和厨房全体补风设备构成，油烟净化器的类型和运转方法能够依据实际情况进行选择。
Composition of kitchen smoke exhaust system The kitchen smoke exhaust system is mainly composed of smoke collecting hood, smoke exhaust pipe, oil smoke purifier, smoke exhaust fan (including silencer) and all air make-up equipment in the kitchen. The type and operation method of oil smoke purifier can be selected according to the actual situation.
Jinan kitchen smoke exhaust has been focused on the industry for many years. Please continue to pay attention to our website for more knowledge about ventilation ducts, oil smoke purifiers and kitchen smoke exhaust schemes: http://www.jnqsg.com
