2 Purpose of the Heat
Pump
2.1 Application
The water-to-water heat pump is to be used exclusively for the
heating of heating water. It can be used in newly built or previ-
ously existing heating systems. Water is used as the heat carrier.
It can be supplied by wells or other water systems.
In order to eliminate the risk of corrosion at the evaporator, the
well water must be evaluated regarding the corrosion behaviour
of metallic materials according to DIN 50930.
Details can be found in the project planning and installation man-
ual for heat pumps for heating purposes.
ATTENTION!
The well water must comply with the required water quality standards.
(see Cap. 9.4 on pag. 8)
2.2 Operating Principle
A well pump conveys the water to the evaporator of the heat
pump. There the heat is transferred to the refrigerant in the refrig-
erating circuit.
The refrigerant is drawn in by the electrically driven compressor,
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 as well.
Subsequently, the refrigerant is passed through the condenser
where it transfers its heat energy to the heating water.
Depending on the set operating point (thermostat setting), the
heating water is thus heated up to a max. of 62 °C.
3 Basic Device
The basic device consists of a ready-to-use heat pump for indoor
installation, complete with casing, switch box and integrated
Heat pump manager. The refrigerant circuit is hermetically
sealed. It contains the Kyoto protocol approved refrigerant
R410A with a GWP value of 1975. It is CFC-free, does not de-
plete ozone and is non-flammable.
All components required for the operation of the heat pump are
located in the switch box. An external wall temperature sensor in-
cluding fixing accessories and a dirt trap are supplied with the
heat pump. The supply for the load current and the control vol-
tage must be installed at the building site.
The supply lead of the well pump (to be provided by the cus-
tomer) must be connected to the switch box. It is important to en-
sure that the integrated motor protection is sufficient for the pump
provided by the customer.
