FIGHTER 1330 consists of two heat pump modules
and a CPU unit with a display to control the heat pump
and any additional heating. FIGHTER 1330 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 compressed
in the compressor. The refrigerant, with its increased
temperature, is led into the condenser where it emits
its energy to the heating medium circuit.
