AlphaFreshbox 200 WiFi
The heat recovery minimises heat loss in the cold season and
thus saves heating costs.
The unit is equipped with a recirculation damper. In
recirculation mode, it is open and the supply and extract air
dampers are closed.
The stale exhaust air flows through
the filters, is cleaned again, and is
then fed further into the room
through a heat exchanger.
Depending on the model, the
ventilation system is equipped with a
pre-heating or post-heating coil. This
provides
automatic
protection
against overheating of the heating
coil.
AlphaFreshbox 200 WiFi is equipped with a pre-heating coil. If
the supply air temperature is below -3 °C, the pre-heating coil
automatically heats the supply air so that the average
temperature of the extract air downstream of the heat
exchanger is not below +5 °C. The extract air fan runs on the
heating coil.
The extract air fan runs at the maximum ventilation level. No
condensate forms in the ventilation system with enthalpy heat
exchanger because the humidity of the extract air is
transferred to the supply air via the enthalpy membrane. The
shutters open automatically when the fan motors are switched
on and close when they are switched off.
