An air handling unit (AHU) with heat recovery is a specialized HVAC system designed to improve energy efficiency by reclaiming heat from exhaust air and using it to pre-condition incoming fresh air. This way, valuable heat doesn’t go to waste—it’s recycled back into the system, saving energy and reducing environmental impact.
Compared to systems with only mechanical exhaust or natural ventilation, heat recovery offers significant energy savings. That’s why heat recovery air handling units are now mandatory in all new buildings in Finland.
Airfi’s AI-powered AFPS™ technology takes this even further. It optimizes the use of the heat recovery core based on weather conditions—defrosting only when truly necessary. The energy for defrosting is taken directly from the exhaust air, making the system even more efficient. If additional heating is required, it is provided by a post-heating element, allowing 100% of the heating energy to be utilized.
The result? Reliable ventilation even during extreme cold spells—without unnecessary energy consumption.
