Main features:
- one central AHU unit (or multiple units for larger buildings) serving the entire building
- balanced ventilation
- heat recovery
- suitable for new buildings
Basic system components:
- one or more central AHUs
- VAV dampers
The system ensures consistently stable indoor environmental quality and a high level of user comfort. Thanks to heat recovery, it also helps reduce the building’s operating costs. To optimise ventilation intensity according to actual occupancy, it is recommended to equip the system with CO₂ sensors.
