Description

Technical Field

[0002] A rotary dehumidifier is a common household appliance used to remove moisture from the air. It operates by using a rotary wheel to absorb and dehumidify air. Inside, the dehumidifier contains a rotor coated with a hygroscopic material, typically silica gel or another absorbent material. As air passes through the rotor, moisture is absorbed onto the rotor. This moisture is then removed from the rotor through heating or other methods, achieving the desired dehumidification effect. Rotary dehumidifiers are often used with waste heat recovery devices to improve the utilization of the heat absorbed during operation. However, existing waste heat recovery devices for rotary dehumidifiers have a relatively rigid structure, with fixed heat exchange tubes, resulting in poor heat exchange performance and significantly impacting heat recovery efficiency.
