Shenyang ventilation pipeline The following is a necessary device for ventilation in buildings, keeping indoor air fresh and indoor humidity Ventilation duct Let's take a look at the characteristics of the two ventilation methods introduced by the manufacturer.

Dilution ventilation. Dilution ventilation is also called mixed ventilation, that is, to send air with lower concentration than indoor pollutants to mix with indoor air, so as to reduce the concentration of indoor pollutants and meet the health standards.

Displacement ventilation. In the displacement ventilation system, fresh cold air is delivered from the bottom of the room at a very low speed (o.03-o.59t/s), and the temperature difference of the supply air is only 2-4Y. The incoming fresh air diffuses at the bottom of the whole room like water due to its high density. The heat convection airflow caused by the heat source causes the room to produce a vertical temperature Zen. The airflow rises slowly, leaves the working area, pushes the waste heat and pollutants to the top of the room, and is discharged directly from the exhaust outlet located on the ceiling or the top of the room.

The indoor air flows like a piston. The pollutants are discharged from the top of the room along with the air flow. The working area is basically in the incoming air, that is, the concentration of pollutants in the working area is approximately equal to the concentration of the incoming air. This is the difference between displacement ventilation and traditional dilution ventilation in all aspects.

There is a slight difference between the two ventilation methods. Compared with the ventilation and sewage discharge effect, the displacement ventilation effect is better. We should set it according to the actual indoor ventilation situation.
