在酒店、餐飲等的廚房中，都會(huì)設(shè)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(shè)備該怎么選擇呢？好的通風(fēng)設(shè)備又是怎么界定的呢？下面由濟(jì)南強(qiáng)順通風(fēng)設(shè)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(fēng)設(shè)備排煙風(fēng)機(jī)需要根據(jù)廚房空間大小和排煙罩的布置情況選擇風(fēng)機(jī)所需要的風(fēng)量來決定。那么該如何計(jì)算出廚房的風(fēng)量、靜壓來選擇適合的通風(fēng)設(shè)備排煙風(fēng)機(jī)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(fēng)設(shè)備排煙風(fēng)機(jī)風(fēng)量的計(jì)算方法
    1. Calculation method of ventilation volume for ventilator and exhaust fan
    1. 通風(fēng)設(shè)備排煙風(fēng)機(jī)的總體排風(fēng)量、根據(jù)廚房空間、每小時(shí)換氣40-60次。例如廚房總面積200平米，高度3米。則需要通風(fēng)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(jù)廚房排煙罩迎風(fēng)面（排煙罩周長(zhǎng)減去靠墻的長(zhǎng)度），每秒風(fēng)速在0.5米左右。比如廚房排煙罩周長(zhǎng)25米、其中靠墻長(zhǎng)度為10米。則需要通風(fēng)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(jì)算風(fēng)機(jī)所需要的靜壓
    Two. Calculate the static pressure needed by the fan
    1. 根據(jù)通風(fēng)設(shè)備排煙風(fēng)機(jī)的風(fēng)量和風(fēng)速（風(fēng)速10-15米/秒左右）確定風(fēng)管截面積。風(fēng)管寬高比例好不要超過2:1（以節(jié)省材料和減小風(fēng)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(jù)通風(fēng)設(shè)備排煙風(fēng)機(jī)的風(fēng)速、風(fēng)管截面積、彎頭、變徑等情況走向計(jì)算出風(fēng)阻（即風(fēng)機(jī)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.
