Background
The air supply ceiling is a core device for ensuring cleanliness and airflow organization so as to provide vertical one-way clean air airflow with balanced flow velocity. Since the local cleaning device is often in an environment with a low degree of sterility, the sterile area (main flow area) exchanges energy with the air in the peripheral area during the air supply process, so that the inner sterile area is easily affected by the environment.
Because the air current only passes through the local area and has larger space around, the air current can not be provided in a centralized way and is easy to disperse, so that the phenomena of turbulence and turbulent flow occur, the utilization rate of the clean air current is reduced, the air supply replacement and dilution functions of the core area are slowed down, and the energy consumption is caused. And the air flow velocity of the air supply at the boundary can be gradually attenuated along with the descending distance, so that the air flow attenuation is slowed down by the air flow velocity of the air supply in the main flow area in the prior art, the air speed at the outlet of the ceiling must be increased, but if the air flow velocity is increased, the air speed is too high, the obvious blowing feeling is caused, and even a whistle or larger noise is caused.
