1.2 How does the M-WRG-S ventilation unit work?
The heat exchanger core uses the heat of the
outgoing warm stale air to temper the fresh inflowing
air. The unit has two fans, one fan extracts the warm
stale air from the interior and the other fan draws in
fresh air from the exterior.
As the air streams move through the air ducts of the
heat exchanger core, heat is transferred from the
warm passage to the cold, while the airstreams are
never combined. The cooled stale air is led out and
the pre-tempered fresh air then streams into the room
without causing a draft.
