Main features of the system:
- air handling unit for each accommodation unit
- even pressure ventilation
- heat recovery
- suitable for new buildings
Basic elements of the system:
- air handling units with ZZT in individual accommodation units
In a decentralised, equal pressure ventilation system with ZZT, fresh thermally treated air is supplied to the room and at the same time, polluted air is removed from the sanitary facilities. Thanks to the heat recovery that takes place in the air handling unit, the system efficiently uses the thermal energy of the exhaust air and reduces the operating costs of the building. The system ensures consistently stable indoor environmental quality and high user comfort.
