Purpose of the Heat Pump

2.1 Application

The brine-to-water heat pump is to be used exclusively for the
heating of heating water. It can be used in new or previously ex-
isting heating systems. The mixture of water and frost protec-
tion (brine) acts as a heat transfer medium in the heat source
system. Ground probes, ground heat collectors or similar sys-
tems can be used as heat source systems.

2.2 Operating Principle

The heat generated by the sun, wind and rain is stored in the
ground. This heat stored in the ground is collected at a low tem-
perature by the brine circulating in the ground heat collector,
the borehole heat exchanger or a similar system. A circulating
pump then conveys the "heated" brine to the evaporator of the
heat pump. There the heat is given off to the refrigerant in the
refrigerating cycle. This cools the brine so that it can once again
absorb thermal energy in the brine circuit.
The refrigerant is drawn in by the electrically driven compres-
sor, compressed and "pumped" to a higher temperature level.
The electrical power needed to run the compressor is not lost in
this process. Most of it is absorbed by the refrigerant.
The refrigerant subsequently passes through the liquifier where
it transfers its thermal energy to the heating water. Depending
on the set operating point (thermostat setting), the heating
water is thus heated up to a max. of 58 °C.

Basic Device

The basic device consists of a ready-to-use heat pump for in-
door installation in a compact design. In addition to the control
panel with integral heat pump manager, the device is already
equipped with all of the most important components of the
heating circuit and the brine circuit:
Expansion vessel

Circulating pumps

 Pressure relief valves
 Pressure gauge
 Overflow valve (heating circuit)
The refrigeration circuit is "hermetically sealed" and contains
the fluorinated refrigerant R410A included in the Kyoto proto-
col. Information on the GWP value and CO
refrigerant can be found in the chapter Device information. The
refrigerant is CFC-free, non-ozone depleting and non-combus-
tible.
All components required for the operation of the heat pump are
located on the control panel. The supply for the load current
and the control voltage must be installed by the customer.
The customer must provide both the heat source system and
the brine circuit manifold.
