Intermediate heat ex-
changer
The product is a brine-to-water heat pump and uses geo-
thermal energy as a heat source.
The heat pump consists of the following separate circuits
which are coupled with one another by means of heat ex-
changers. These circuits are:
–
The brine circuit, which extracts the thermal energy from
the ground or the ground water and transfers this to the
refrigeration circuit
–
The refrigerant circuit, which is used to bring the thermal
energy from the ground to a usable, higher temperature
level and deliver it to the heating circuit
–
The heating circuit, which is used to heat up the living
rooms
