Geothermal Heat Pumps

Function principle F 1220
FIGHTER 1220 consists of heat pump, hot water tank, cartridge heater, circulation pumps and control system. FIGHTER 1220 must be connected to a heat source and heating circuit. The heat absorption from the heat source (soil, brine, ground water) is usually performed by a closed system in which a mixture of water and antifreeze circulates. Ground water can also be utilized as a heat source, however this necessitates a heat exchanger, which is installed in-between. In the evaporator the heat pump gives off its energy to the refrigerant, which evaporates and is subsequently compressed in the compressor. The refrigerant, the temperature of which has now been raised, is passed to the condenser where it gives off its energy to the heating circuit and if necessary to the water heater tank. The installed cartridge heater lies behind the condenser, which is automatically activated at higher energy.
