做饭时一般都会有油烟，那么就需要有关管道发挥作用了，但往往会排不干净，这是为什么呢？接下来我们就一起来聊聊这个事儿。
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.
在抽油烟机的机械推动下，油烟通过连接软管进入垂直烟道，沿烟道上升，从上排风口排出。屋顶。当油烟在烟道中上升时，遇到阻力就减速，使烟道内的气压高于外界的气压，从而防止油烟从油罩中排出。
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.
一般来说，济南厨房排气决定抽油烟机的排风效果，不仅取决于吸风量，更重要的是取决于抽油烟机的风压值指标。如果烟管较长或与公共烟道相连，废气的压力损失会很大，因此需要较大的风压，以保证烟气和空气全部排出。
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，在其他指标相近的情况下，风压值越大，排气效果越好。一些局部柜式空调通常安装在餐厅内，以降低餐厅的室内温度，但室内空气供给厨房，不能厨房的热负荷，降低厨房的温度。因此，排烟工程中应尽量减少无序送风的使用。
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.
有序的通风更灵活，厨房的工作环境也能得到保证。目前比较好的有序送风方式是将组合式空调的新风一部分直接送入厨房，一部分送入餐厅，通过回风机返回空调。这样可以部分解决新风能耗高的问题，同时使用的灵活性也更大。
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.
当厨房所有排风扇都工作且负压升高时，回风电动阀关闭，回风停止，餐厅向厨房大量送风；当少量排气扇开启或排气扇不工作时，负压不是很大。然后打开回风电动阀，启动回风机，防止空调送风全部排出。
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.
Ji 'nan kitchen exhaust smoke exhaust is not clean what is going on? After the above content analysis, we probably already know what is going on, so more content to the website http://www.jnqsg.com consultation!
