  厨房排气系统的排风量应根据排烟罩的大小、污染物的排放、厨房的大小、炉子的数量来确定。一般推荐使用以下三种方法来确定厨房排烟系统的合适排风量:
  The exhaust volume of kitchen exhaust system should be determined according to the size of exhaust hood, pollutant discharge, kitchen size and the number of stoves. It is generally recommended to use the following three methods to determine the appropriate ventilation volume of the kitchen smoke exhaust system:
  1. 根据排烟罩的大小确定厨房排风系统的排风量:用排烟罩底边与灶台之间的进风面积与进风速度的乘积来计算排风量更为合适。排风量计算公式如下:G=3600L (h2-h1) Vx, m3/h L——烟机下进气面长度(同时计算烟机两端长度和两侧进气另一侧长度),m;H1——炉缸高度,m;H2——烟罩高度m;进口速度,m/s。
  1. Determine the exhaust volume of kitchen exhaust system according to the size of exhaust hood: It is more appropriate to calculate the exhaust volume by multiplying the area of air intake and the velocity of air intake between the bottom of exhaust hood and the stove. The calculation formulas of exhaust air volume are as follows: G = 3600L (h2-h1) Vx, m3/hL - length of the lower intake surface of the flue gas machine (while calculating the length of both ends of the flue gas machine and the length of the other side of the intake), m; H1 - height of hearth, m; H2 - height of hood, m; inlet speed, m/s.
  2. 根据污染物排放量设计厨房排烟系统的排风量:按照国家环保gb18483-2001《餐饮业排烟标准》,每个炉子的排风量为2000m3/h。作者认为,按这种方法进行风量设计仍有一定的局限性。事实上,餐饮业的实际情况是复杂的:炉子的尺寸,炉子有广式、苏式等。除了灶头还有汤锅、煲仔、锅灶等;从功能上看,有烹饪室、烹饪室、糕点室、烧烤室、西餐加工室、洗碗室等,散热与污染物排放是不同的,不能简单地根据灶头的数量来确定排风量。

  2. Design the exhaust air volume of kitchen smoke exhaust system according to the pollutant discharge: According to the national environmental protection GB18483-2001 "Food and Beverage Smoke Exhaust Standard", the exhaust air volume of each stove is 2000 m3/h. The author considers that there are still some limitations in air volume design based on this method. In fact, the actual situation of catering industry is complex: the size of stoves, stoves have Cantonese, Soviet and so on. Besides the stoves, there are soup pots, cookers, cooking stoves, etc. From the functional point of view, there are cooking rooms, cooking rooms, pastry rooms, barbecue rooms, Western food processing rooms, dish-washing rooms, etc. Heat dissipation and pollutant emissions are different, so we can not simply determine the amount of exhaust air according to the number of stoves.
  3.通过通风频率确定厨房排烟系统的排风量:各厨房之间的差异较大,厨房面积与厨房厨具的数量、烹饪范围不成正比,同一厨房产生的污染物和热量也不同。其实,厨房通风并不全面,按照通风数量来设计风量会有很大的误差。
  3. Determine the exhaust air volume of kitchen smoke exhaust system by ventilation frequency: there are great differences among kitchens, kitchen area is not proportional to the quantity and cooking range of kitchen kitchen utensils, and the pollutants and heat produced by the same kitchen are also different. In fact, the kitchen ventilation is not comprehensive, according to the number of ventilation to design air volume will have a great error.
