A, duct ventilation cross-sectional area
Often, when the kitchen exhaust pipe for the installation, due to the pipeline through the building beams, the cross-sectional area of the pipeline ventilation becomes smaller, resulting in the pipeline airflow is not smooth, resulting in exhaust is not smooth.
Two, the ventilation area of the main exhaust pipe
The main flue is spread throughout the building, and the secondary flue is relatively independent. According to some experienced masters, the exhaust pipe main flue wind speed is best controlled within 15m/s, which is the most appropriate.
Three, the design and installation of the pipe
The kitchen exhaust pipe is like the stomach of the whole exhaust system. If the design and installation is not reasonable, it will often lead to insufficient exhaust capacity and unsatisfactory purification of smoke.
Four, low level smoke is not smooth
Kitchen fumes from different floors are discharged through the same main pipe, and kitchens on the floor close to the exit will have a better smoke evacuation effect, while kitchens on the lower floors will have a relatively poor smoke evacuation effect.
Fifth, there is debris in the exhaust pipe
When the kitchen exhaust pipe for the installation, because the pipe needs to pass through the building beams or avoid other equipment, a part of the pipe will be lower than the whole exhaust pipe, which makes it possible to oil-water mixture or other debris. It accumulates in the lower part of the pipe, causing smoke blockages.
To use the kitchen exhaust pipe smoothly, the above five points should be paid special attention to, so as not to cause unnecessary dissatisfaction to the residents and unnecessary disputes.
