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.
High-Efficiency Evaporative Technology: Significantly reduces energy consumption for fresh air treatment.
