Heat Recovery Unit (Industrial Air To Air Heat Exchanger)

An industrial air - to - air heat exchanger - type heat recovery unit is a device that utilizes the temperature difference between exhaust air and fresh air in industrial settings to recover waste heat and transfer it to the incoming fresh air, thereby achieving energy conservation and efficiency enhancement.

Working principle: The heat recovery unit is equipped with heat - exchange elements. When exhaust air and fresh air flow through the heat - exchange elements simultaneously, heat is transferred from the high - temperature exhaust air to the low - temperature fresh air through heat conduction and convection, enabling the pre - heating or pre - cooling of the fresh air and reducing the energy consumption required for subsequent air - conditioning or heating treatments.

Advantages

Energy conservation and emission reduction: It recovers the waste heat from the exhaust air, reduces the energy consumption of the air - conditioning and heating systems, and thereby reduces carbon emissions and other environmental pollutants.

Cost - effective: It can save on energy costs, and although there is an initial equipment investment, the payback period is generally relatively short, bringing economic benefits in the long term.

Improved indoor air quality: By pre - treating the fresh air, it can improve the temperature and humidity conditions of the incoming air, enhance indoor comfort, and contribute to a healthy indoor environment.

Applications

HVAC systems in industrial buildings: Such as factories, warehouses, and workshops, where a large amount of exhaust air is generated during the production process. The heat recovery unit can recover the waste heat from the exhaust air and use it to pre - heat or pre - cool the fresh air, reducing the energy consumption of the HVAC system.

Process industries: In industries such as chemical, pharmaceutical, and food processing, there is often waste heat in the exhaust gas from production processes. The heat recovery unit can recover this waste heat and use it for process heating, pre - heating of raw materials, or other purposes, improving the energy efficiency of the production process.

Power plants: In power plants, the flue gas generated during coal combustion contains a large amount of waste heat. The heat recovery unit can recover the waste heat from the flue gas and use it for heating the combustion air, pre - heating the feed water, or other purposes, improving the thermal efficiency of the power plant.
