For Home Owners
FIGHTER 360P
FIGHTER 360P comprises an electric boiler with a
copper lined water heater and a heat pump which
recovers energy from the ventilation air. The recovered
energy is supplied to the heat pump. The heat pump
must be installed in a ventilation system intended for
mechanical exhaust air.
The output of the immersion heater is max 6,0 kW.
When the exhaust air at room temperature passes
through the evaporator, the refrigerant evaporates
because of its low boiling point. In this way the heat in
the room air is transferred to the refrigerant.
The refrigerant is then compressed in a compressor,
causing the temperature to rise considerably.
The warm refrigerant is fed to the condenser, which is
in the boiler water. Here the refrigerant gives off its
heat to the boiler water, so that its temperature drops
and the refrigerant changes state from gas to liquid.
The refrigerant then goes via filters to the expansion
valve, where the pressure and temperature are further
reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.
When the room air has
passed through the heat
pump it is discharged. The
temperature of the air has
been significantly reduced
as the heat pump has
extracted the energy in the
room air.
The air from the
kitchen fan goes
directly out into a
separate duct.
The warm room
air is fed to
FIGHTER 360P
FIGHTER 360P supplies
the house with both hot
water and room heating.
Outdoor air is drawn
into the house.
The warm room air is
drawn into the air duct
system.
Air is transported
from rooms with
outdoor air devices to
rooms with exhaust
air devices.
