When cooking, there will be lampblack in general, so you need to play a role in the pipeline, but often not clean, why is this? Let's talk about that.

　　在抽油煙機的機械推動下，油煙通過連接軟管進入垂直煙道，沿煙道上升，從上排風口排出。屋頂。當油煙在煙道中上升時，遇到阻力就減速，使煙道內的氣壓高于外界的氣壓，從而防止油煙從油罩中排出。

　　Under the mechanical drive of the range hood, the lampblack enters the vertical flue through the connecting hose, rises along the flue, and is discharged from the upper exhaust outlet. The roof. When the lampblack rises in the flue, it decelerates when encountering resistance, so that the air pressure in the flue is higher than that of the outside world, so as to prevent the lampblack from being discharged from the oil hood.

　　一般來說，濟南廚房排氣決定抽油煙機的排風效果，不僅取決于吸風量，更重要的是取決于抽油煙機的風壓值指標。如果煙管較長或與公共煙道相連，廢氣的壓力損失會很大，因此需要較大的風壓，以保證煙氣和空氣全部排出。

　　Generally speaking, ji 'nan kitchen exhaust determines the exhaust effect of the range hood, not only depends on the suction air volume, but more importantly depends on the air pressure index of the range hood. If the smoke pipe is long or connected to a public flue, the pressure loss of the exhaust gas will be large, so a high wind pressure is needed to ensure that the smoke and air are fully discharged.

　　因此，在其他指標相近的情況下，風壓值越大，排氣效果越好。一些局部柜式空調通常安裝在餐廳內，以降低餐廳的室內溫度，但室內空氣供給廚房，不能廚房的熱負荷，降低廚房的溫度。因此，排煙工程中應盡量減少無序送風的使用。

　　Therefore, in the case of similar other indicators, the higher the wind pressure value, the better the exhaust effect. Some local cabinet air conditioners are usually installed in the restaurant to reduce the indoor temperature of the restaurant, but the indoor air supply to the kitchen can not eliminate the heat load of the kitchen and reduce the temperature of the kitchen. Therefore, the use of disordered air supply should be reduced as far as possible in smoke exhaust engineering.

　　有序的通風更靈活，廚房的工作環境也能得到保證。目前比較好的有序送風方式是將組合式空調的新風一部分直接送入廚房，一部分送入餐廳，通過回風機返回空調。這樣可以部分解決新風能耗高的問題，同時使用的靈活性也更大。

　　Orderly ventilation is more flexible, and the working environment of the kitchen can be guaranteed. At present, a better way of orderly air supply is to send part of the fresh air of the combined air conditioner directly into the kitchen and part of the fresh air into the restaurant, and return the air conditioner through the return fan. In this way, the problem of high energy consumption of fresh air can be partially solved, and the flexibility of use is also greater.

　　當廚房所有排風扇都工作且負壓升高時，回風電動閥關閉，回風停止，餐廳向廚房大量送風；當少量排氣扇開啟或排氣扇不工作時，負壓不是很大。然后打開回風電動閥，啟動回風機，防止空調送風全部排出。

　　When all kitchen exhaust fans are working and the negative pressure increases, the return air electric valve is closed, the return air stops, and the restaurant supplies a large amount of air to the kitchen; Negative pressure is not very large when a small number of exhaust fans are open or the exhaust fans are not working. , and then open the return air electric valve, start the return fan, to prevent all the air supply from being discharged.
