Description

Technical Field

[0001] The utility model relates to the technical field of rotary wheel dehumidifiers, in particular to a new air handling unit with a double - fan controlled rotary wheel. Background Art

[0002] A rotary wheel dehumidifier is a device for dehumidification. Its core component is a rotary wheel, usually composed of a hygroscopic agent and a carrier. This dehumidifier works based on the principle of physical adsorption. Through the rotation of the rotary wheel, moisture in the air is adsorbed on materials with high water absorption such as silica gel or activated carbon, and then the dried air is sent into the workshop to achieve the purpose of humidity control. The structure of the rotary wheel dehumidifier mainly includes a machine body, an air inlet, an air outlet, a rotary wheel, a driving device, and a control system, etc. Among them, the rotary wheel is divided into a moisture absorption area and a regeneration area. In the moisture absorption area, the hygroscopic agent in the rotary wheel absorbs water molecules in the air and stores them in the rotary wheel; in the regeneration area, the moisture in the hygroscopic agent is heated and released back into the air. Through the continuous rotation of the rotary wheel, the two processes of moisture absorption and regeneration are continuously carried out, effectively removing moisture in the air. However, the existing rotary wheel dehumidifiers have poor dehumidification effects and cannot be applied to multiple scenarios, having certain limitations and reducing the applicability of the rotary wheel dehumidifiers.
