在酒店、餐飲等的廚房中，都會設置廚房排煙工程，主要是將廚房里面的油煙排到外面。那么排煙工程的設備該怎么選擇呢？好的通風設備又是怎么界定的呢？下面由濟南強順通風設備有限公司小編為您一一講解。
    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.
    選擇通風設備排煙風機需要根據廚房空間大小和排煙罩的布置情況選擇風機所需要的風量來決定。那么該如何計算出廚房的風量、靜壓來選擇適合的通風設備排煙風機呢？
    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、通風設備排煙風機風量的計算方法
    1. Calculation method of ventilation volume for ventilator and exhaust fan
    1. 通風設備排煙風機的總體排風量、根據廚房空間、每小時換氣40-60次。例如廚房總面積200平米，高度3米。則需要通風量為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. 局部根據廚房排煙罩迎風面（排煙罩周長減去靠墻的長度），每秒風速在0.5米左右。比如廚房排煙罩周長25米、其中靠墻長度為10米。則需要通風量為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、計算風機所需要的靜壓
    Two. Calculate the static pressure needed by the fan
    1. 根據通風設備排煙風機的風量和風速（風速10-15米/秒左右）確定風管截面積。風管寬高比例好不要超過2:1（以節省材料和減小風阻）。
    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. 根據通風設備排煙風機的風速、風管截面積、彎頭、變徑等情況走向計算出風阻（即風機所需要的靜壓）。
    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.
