在酒店、餐饮等的厨房中，都会设置厨房排烟工程，主要是将厨房里面的油烟排到外面。那么排烟工程的设备该怎么选择呢？好的通风设备又是怎么界定的呢？下面由济南强顺通风设备有限公司小编为您一一讲解。
In the kitchens of hotels, restaurants, etc., kitchen smoke exhaust projects are set up, mainly to drain the fumes inside the kitchen. So how to choose the equipment for the exhaust project? How does a good ventilator define it? The following is the Ji'nan Xiaobian ventilation equipment Co., Ltd. for you to explain one by one.
选择通风设备排烟风机需要根据厨房空间大小和排烟罩的布置情况选择风机所需要的风量来决定。那么该如何计算出厨房的风量、静压来选择适合的通风设备排烟风机呢？
Selection of ventilation and exhaust fans depends on the size of the kitchen space and the layout of the exhaust hood to determine the air volume required by the fan. So how do we calculate the air volume and static pressure of the kitchen to choose suitable ventilation and exhaust fans?
一、通风设备排烟风机风量的计算方法
1. Calculation method of ventilation volume for ventilator and exhaust fan
1. 通风设备排烟风机的总体排风量、根据厨房空间、每小时换气40-60次。例如厨房总面积200平米，高度3米。则需要通风量为24000m3/h-36000m3/h。
1. ventilator exhaust fan overall exhaust volume, according to the kitchen space, hourly ventilation 40-60 times. For example, the total area of the kitchen is 200 square meters, and the height of the kitchen is 3 meters. The amount of ventilation is 24000m3/h-36000m3/h.
2. 局部根据厨房排烟罩迎风面（排烟罩周长减去靠墙的长度），每秒风速在0.5米左右。比如厨房排烟罩周长25米、其中靠墙长度为10米。则需要通风量为3600X（25-10）X0.5= 27000m3/h.
The 2. part according to the kitchen exhaust hood face (smoke exhaust hood circumference minus the length of the wall), the wind speed is about 0.5 meters per second. For example, the kitchen exhaust hood circumference is 25 meters, and the wall length is 10 meters. The ventilation volume is 3600X (25-10) X0.5= 27000m3/h..
二、计算风机所需要的静压
Two. Calculate the static pressure needed by the fan
1. 根据通风设备排烟风机的风量和风速（风速10-15米/秒左右）确定风管截面积。风管宽高比例好不要超过2:1（以节省材料和减小风阻）。
1. determine the cross section area of the ventilation pipe according to the air volume and wind speed of the ventilator exhaust fan (around 10-15 M / s). The ratio of width to height of the duct is best not to exceed 2:1 (to save material and reduce wind resistance).
2. 根据通风设备排烟风机的风速、风管截面积、弯头、变径等情况走向计算出风阻（即风机所需要的静压）。
2. according to the wind speed, the cross section area of the air duct, the elbow and the variable diameter of the ventilator, the wind resistance (i.e. the static pressure required by the fan) is calculated.
