Functional description

The unit has a heat exchanger. The heat exchanger continuously extracts heat from the stale room air (extract air) and
transfers this heat to the fresh intake air, which flows into all rooms connected to the duct system as pre-heated, filtered
Bei Verwendung eines Heizregisters, muss das Rohrsystem 0,5 m vor und nach dem Heizregister
supply air. The stale air is extracted from the connected rooms via the duct system. It flows through the duct system
mit temperaturbeständigem bzw. nicht brennbarem Rohr versehen werden (z.B. Wickelfalzrohr)
back to the ventilation unit, gives off heat and is led outside through the exhaust air duct (see Fig. 2).
The heat recovery efficiency depends on the factors of humidity and the temperature difference between intake and
extract air.
