Air Handling Unit with Heat Recovery
An air handling unit (AHU) with heat recovery is a core HVAC (Heating, Ventilation, and Air Conditioning) device that integrates heat recovery functionality into a standard air handling unit.
It’s designed to transfer heat (or cold) between the building’s exhaust air (polluted, with waste heat/cold) and incoming fresh air (outside air needing temperature adjustment) during ventilation. This process reuses the waste thermal energy, reducing the load on heating or cooling systems and cutting energy consumption.
Key Working Principles The unit has two independent air flows: one for exhaust air (from indoors) and one for fresh air (from outdoors).
A heat exchanger inside the unit facilitates heat transfer between the two streams—no direct mixing of air, ensuring indoor air quality.
In winter: Waste heat from warm exhaust air preheats cold fresh air, reducing the need for additional heating.
In summer: Cool exhaust air precools hot fresh air, lowering the load on air conditioning systems.
Typical ApplicationsCommercial buildings: Office buildings, shopping malls, hotels, and hospitals (requiring large-scale ventilation and energy savings).
Industrial facilities: Factories, data centers, and clean rooms (needing stable indoor temperature/humidity and high energy efficiency).
Green buildings: A key component to meet energy-saving standards and reduce carbon emissions.
Core Advantages
Energy efficiency: Cuts HVAC energy consumption by 15%-40% compared to standard AHUs, lowering operating costs.
Environmental friendliness: Reduces carbon emissions by reusing waste heat, aligning with low-carbon development goals.
Comfort enhancement: Stabilizes the temperature of incoming fresh air, avoiding sudden temperature fluctuations indoors.
