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
supply air. The stale air is extracted from the connected rooms via the duct system. It flows through the duct system
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. Units with enthalpy heat exchangers (KWL 500 W ET) recover humidity from the extract air in addition
to heat, which is returned to the rooms through the supply air.
