PUMP

2.1 Application

The water-to-water heat pump is designed for
use in existing or newly built heating systems.
Water, which can be supplied from wells, or the
like, is used as the heat carrier.
To prevent any corrosion damage to the eva-
porator, the well water must be evaluated in
accordance with DIN 50930 as to the corrosion
risk of metallic materials.
More details are contained in the Project Planning
and Installation Manual for heat pumps for
heating purposes.
CAUTION!
The well water must meet the estab-
lished water quality standards.

2.2 Principle of Operation

A well pump conveys the water into the evaporator
of the heat pump where it gives off heat to the
refrigerant in the refrigeration cycle.
The refrigerant is then "sucked in" by the
electrically driven compressor, is compressed
and "pumped" to a higher temperature level. The
electrical power needed to run the compressor
is not lost, but most of the generated heat is
transferred to the refrigerant as well.
Subsequently, the refrigerant is passed through
the condenser where it transfers its heat energy
to the heating water.
Based on the thermostat setting, the heating
water is thus heated to up to 55 °C.

BASELINE UNIT
The baseline unit consists of a heat pump, ready
for connection, for indoor installation, complete with
housing, control panel and integrated controller.
The refrigeration cycle contains the refrigerant
R407C. The refrigerant is CFC-free, non-ozone
depleting and non-combustible.
All components required for the operation of the
heat pump are integrated in the control panel.
The power feed for the load and control current
must be field-installed by the customer.
The supply lead of the well pump (to be provided
by the customer) must be connected to the control
panel. When so doing, check whether the capacity
of the factory-installed motor protecting device is
adequate for the field-installed pump.
