The fresh air of the air supply system is introduced by the fresh air module, dust is removed through the dust removal and sterilization module, and after bacteria are killed, the central controller distributes the fresh air to each room according to the detection result of the air quality sensor and the rules built in the central controller. By adopting the air supply system, dust of fresh air is removed, bacteria are killed, and air supply is clean and clean. Moreover, the central controller can distribute fresh air according to the detection values of the air quality sensors, so that the requirements of each room are met, and meanwhile, the energy consumption is reduced.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
