FIGHTER 1320 consists of two heat pump modules
and a CPU unit with a display to control the heat pump
and any additional heating. FIGHTER 1320 has built-
in circulation pumps, making it easy to connect to the
heating medium and brine circuits.
The energy from the heat source is taken up via a
closed collector system in which a mixture of water
and antifreeze circulates. The heat source can be
rock, soil, lake, exhaust air or other process heating.
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 com-
pressed in the compressor. The refrigerant, with its
increased temperature, is led into the condenser
where it emits its energy to the heating medium circuit.
