The main functions of heat wheel include heat recovery and dehumidification. The heat wheel transfers heat through heat storage elements and uses rotors to exchange heat between hot air flow and cold air flow, thereby achieving the effect of heat recovery and dehumidification. Specifically, the heat wheel relies on a rotor rotating at a low speed, and the rotor is filled with heat storage elements. When the hot air flow passes through the rotor, the heat storage element absorbs and stores heat. As the rotor rotates, the heat storage element releases heat in the cold air flow, thereby achieving heat transfer.
Principle of heat recovery and dehumidification
The working principle of the heat wheel is to achieve heat exchange between cold and hot air flows through the rotation of the rotor. Part of the rotor is in the hot air flow, and the other part is in the cold air flow. When the hot air flow passes through the heat storage element of the rotor, the element absorbs and stores heat; when the rotor rotates to the cold air flow area, the element releases heat to the cold air flow, thereby achieving heat transfer. This low-speed rotation process allows the cold and hot air flows to exchange heat continuously.
