Thoroughly thought through.
Genius in operation
Heating mode
The heating load is covered by an increase in the
volumetric ow. This requires a separate duct system.
A fan, which is controlled in parallel to the heat pump,
removes secondary air from the living area. This is
warmed with the heat pump and fed back into the living
and sleeping quarters as supply air.
The extract air system remains completely untouched,
ensuring that contamination of the supply air is excluded.
Only the residual energy in the exhaust air, after heat
recovery, is used as an additional heat source by the
heat pump.
Ventilation mode
The extract air is extracted via the kitchen, bathroom and
WC. On its way to the outside, it ows over the rotary
heat exchanger. At the same time, fresh air is drawn in
from the outside and is also passed through the heat
exchanger. With each rotation of the heat exchanger,
both supply air and extract air ow through the cells. In
this way, heat from the extract air is transferred to the
supply air. In summer, the principle functions in reverse,
so that the cooler extract air pre-cools the warmer
supply air.
As well as heat, the rotary heat exchanger also recovers
humidity. This means that the atmospheric humidity is
generally always within a comfortable range.
Cooling mode
The cooling mode works in the same way as the heating
mode, except that the heat pump is working in reverse.
This means that the evaporator becomes the condenser
and the condenser becomes the evaporator. The heat
pump extracts heat from the house or apartment, which
is then discharged to the outside.
