Main features:
- roof fans for individual riser ducts and decentralized ventilation units for each accommodation unit
- exhaust ventilation
- heat recovery
- suitable for renovation projects
Basic system components:
- roof fans
- electrically controlled extract air valves
- decentralized ventilation units with heat recovery in each accommodation unit
In this central exhaust system with heat recovery, exhaust air is extracted from multiple accommodation units through a shared duct system connected to roof fans. Fresh air is supplied by decentralized ventilation units, where heat recovery takes place via a heat exchanger, ensuring a continuous supply of thermally treated fresh air to the interior. Compared to conventional exhaust ventilation systems, this solution provides higher user comfort and helps reduce the building’s energy consumption.
