Polluted warm air is extracted from the room and while flowing
through the heat exchanger warms it up and transfers a part of
humidity.
•
After the ceramic heat exchanger gets warmed up the unit changes
into air supply mode.
•
While flowing through the heat exchanger fresh cold air
from outside absorbs accumulated heat and moisture.
•
As the heat exchanger cools down the unit changed into
air extract mode.
