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.
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.
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.
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.
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.
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.deasiled.com consultation!
