Intended use of the heat
pump
2.1 Intended purpose
The high-efficiency compact brine-to-water heat pump with
built-in domestic hot water cylinder is intended only for heating
water and process water. It can be used in new or existing heat-
ing systems. The mixture of water and frost protection (brine)
acts as a heat transfer medium in the heat source system.
Ground probes, ground heat collectors or similar systems 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, the heating water is thus heated up
to a max. of 62 °C.

Basic device
3.1 General
The basic device consists of a ready-for-use heat pump for in-
door installation in a compact design with built-in domestic hot
water cylinder.
All components required for the operation of the heat pump are
located on the switch box with heat pump manager. An outside
temperature sensor including fixing accessories and a dirt trap
are supplied with the heat pump. The supply for the load cur-
rent and the control voltage must be installed by the customer.
The customer must provide both the heat source system and
the brine circuit manifold.
