Nibe FIGHTER 1110 - System Description; Principle of Operation

FIGHTER 1110 consists of a heat pump module and a
control computer with a display for operating the heat
pump and a soft-start relay (5-15 kW) and additional
heat (immersion heater not included in the basic
design). FIGHTER 1110 has built-in circulation
pumps, making it easy to connect to the heating medi-
um and brine circuits.
The absorption of heat from the heat source (rock,
ground or lake) is through a closed collector system
containing water mixed with antifreeze.
Ground water can also be used as a heat source. This
requires an intermediate heat exchanger.
The brine fluid emits its heat to the refrigerant in the
heat pump’s evaporator. It then vaporises and is com-
pressed in the compressor. The refrigerant, with its
increased temperature, is led into the condenser
where it emits its energy to the heat medium circuit.
