Displacement ventilation. In displacement ventilation systems, fresh air is delivered at a very low speed (o.03 - o.59t/s) at the bottom of the room, with a temperature difference of only between 2 - 4Y.
Kitchen smoke pipe installation, gas and gas pipeline renovation needs to be careful. The two pipes are limited by the structure of the house and are generally not allowed to change at will. If you have to change, you must go through the consent of the property company. When changes due to the professional ability, but also facilitate the day after maintenance.
From the point of view of building structure design, exhaust pipeline engineering because of the main and auxiliary points are not random horizontal flue changes, otherwise it will affect the smoke and flooding may, in order to beautiful will have a bad effect on mobile will not export flue.
If the exhaust pipe is installed hood hood (mostly Western Pyramid) to the vertical flue, flue and stainless steel decorative plate, the flue mouth can change into the ceiling, if it is because of Chinese style cigarette flue ducts outside the general decoration board, is the need to change the proper position of flue opening in the ceiling, so that flue catheter decorative plate or from the hood cabinet with hood connection.
Into the fresh air because of high density and like water filled the whole room at the bottom of the heat caused by heat to produce indoor vertical temperature of air flow of Zen, slowly rising, out of the work area, the waste heat and pollutants to the top of the room, by the end of the air outlet in the roof or room at the top of the direct discharge.
The indoor air is approximately piston like. The pollutants in the air flow from the top of the room work area is discharged into the air, the concentration of pollutants concentration of work area is approximately equal to give air, this is the biggest difference with the traditional full dilution ventilation ventilation.
