Example 2: Ventilation solution for a 3-room
flat with LD 30 BK (bathroom) and LD 45
(living spaces) ventilation units.
The LD 30 BK aerates and ventilates the
bathroom at the same time with balanced
operation. A LD 30 BK fan ventilates the room
with air which has been pre-warmed in the
heat exchanger. The other LD 30 BK fan
transfers the heat energy from the exhaust air
to the heat exchanger during air extraction.
Every 60 seconds, the air direction changes,
thereby permitting a ventilation mode with
constant heat recovery.
In case of high air humidity, intensive venti-
lation can be activated via a humidity sensor
(automatically) or manually with a button.
Pure exhaust air mode is also possible and
here the two fans pump humidity out of the
room (no heat recovery).
