The structural features of heat recovery wheel mainly include the following aspects:
Core component: The core component of heat recovery wheel is a slowly rotating honeycomb wheel, usually made of aluminum alloy, galvanized steel or other corrosion-resistant materials. This wheel is divided into two parts, one for exhaust and the other for fresh air.
Working principle: The waste hot air taken away from the building or equipment by exhaust air flows through the heat recovery part and transfers the heat to the material of the wheel. Fresh air flows in from the outside and passes through the other part of the wheel. Since the wheel has been heated by the exhaust gas, the fresh air will absorb the heat from the wheel and be preheated. The wheel rotates slowly, bringing the heat in the exhaust air to the fresh air side to achieve heat recovery.
Material selection: The material of the wheel is generally aluminum foil, and the material of the full heat recovery wheel is aluminum foil material with a hygroscopic surface or other heat storage and hygroscopic materials. Fresh air passes through one semicircle of the rotor, while exhaust air passes through the other semicircle of the rotor. Fresh air and exhaust air flow alternately through the rotor in opposite directions to complete full heat exchange.
Application scenarios: Rotary air heat recovery units are commonly used in ventilation, air conditioning and air handling systems in industrial and commercial fields. It is suitable for places that require a large amount of fresh air, such as factory workshops, food processing workshops, etc., as well as large office buildings, hotels and other commercial building air conditioning systems. In addition, it is also suitable for places that require a constant temperature and humidity environment, such as hospitals, laboratories, etc.
