System description
Principle of operation
FIGHTER 1127 consists of a heat pump module and a control
system with a display for operating the heat pump, soft start
relay (8-12 kW) and additional heating. FIGHTER 1127 has
built-in circulation pumps, making it easy to connect to the
heating medium and collector 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 emits its heat to the refrigerant in the heat pump's
evaporator. It then vaporises and is compressed in the com-
pressor. The refrigerant, with its increased temperature, is
led into the condenser where it emits its energy to the
heating medium circuit.
In the event of cooling, the direction of flow changes in the
refrigerant system. Even the external systems (brine and
heating medium) change direction by the external pumps
starting for opposite circulation. The heat energy is now
emitted to the heat source (via the collector) which is re-
charged.
