排风量要根据厨房大小、炉灶的数量、烟罩的尺寸、污染物的散发量来确定。一般有几种方法确定厨房的排风量：
The exhaust air volume should be determined according to the size of the kitchen, the number of stoves, the size of the hood, and the emission of pollutants. There are several ways to determine the kitchen exhaust:
（1）按换气次数确定排风量：
(1) according to the number of air exhaust:
各家厨房差别较大，厨房面积与厨具、炉灶的数量不成正比，同样灶的产生的污染物和热量也差别很大。实际上厨房通风并非是通风，按换气次数设计风量会有很大的误差。
The difference between the larger kitchen, kitchen area and kitchen utensils, stove number is not proportional to the same range of pollutants and heat generation is also very different. In fact, the kitchen ventilation is not fully ventilated, according to the number of ventilation design will have a great error.
（2）按污染物散发量的多少设计排风量：
(2) according to the amount of pollutant emission design exhaust air:
GB18483-2001《饮食业油烟排放标准》规定每个灶头需风量2000m3/h。笔者认为按照此方法设计风量仍有局限性。实际上饮食业的实际情况要复杂：炉灶大小，炉灶有广式、苏式等分别；除了灶头外还有汤锅、煲仔、蒸锅烤箱等；在功能上，有烹调间，蒸煮间，面点间，烧烤间，西餐加工间，洗碗间等，散热量及污染物散发量都不同，简单按灶头数量确定排风量是不适当的。
The state environmental protection GB18483-2001 "standard" cooking fume emission regulations of each burner air volume 2000m3/h. According to this method, the author thinks that the design of air volume is still limited. The actual situation in the catering industry is more complicated: the oven size, a wide type, Su type stove and stove respectively; in addition, the pot pot, steamer oven etc.; in function, there are cooking, cooking, pastry, barbecue, Western-style food processing room, washing room, heat and pollutant emissions are different, according to the simple stove quantity to determine exhaust volume is not appropriate.
厨房安装抽风柜排风应避免大量的空调空间内的空气被抽排。需要通过自然补风和机械补风避免之。无论是自然补风还是抽风柜补风都要考虑新风通过的路径，避免死区，以利于室内污染空气的抽排。机械补风要通过风管和送风口进行，管路系统不可复杂，同时避免局部风速过大。新风补充量以排风量的70%-80%为宜。
Kitchen installation exhaust fan exhaust should avoid a large number of air space in the air was pumped out. Natural ventilation and mechanical ventilation are needed to avoid. Whether it is natural to fill the air or exhaust air supply must consider the path of fresh air through the road, to avoid dead zones, in order to facilitate the indoor exhaust air pollution. Mechanical air supply through the wind pipe and air outlet, pipeline system can not be complicated, while avoiding the local wind speed is too large. The amount of fresh air to exhaust air volume of 70%-80% is appropriate.
