Integration of the Heat Pump in the Heating System 8.12.1
8.12.1 Integration of the heat source
The heat source primary pump M11 transports the recovered
environmental heat to the evaporator of the heat pump. In air-to-
water heat pumps this task is carried out by the integrated
ventilator.
The integration of the ground or ground water as heat source can
be seen in the following figures.
Ground as heat source
Fig. 8.19: Schematic representation of brine-to-water heat pumps
Every brine circuit should be
provided with a shutoff valve for
ventilation.
All the brine circuits must be of
the same length to ensure that
each has an equal flow and
abstraction capacity.
The filling and breather
mechanisms should be installed
at the site's highest point.
A large-capacity breather should
be installed at the highest and
warmest possible point of the
brine circuit.
The brine circulating pump of
the heat source system should
preferably be installed outside
the building and protected
against rain.
The pump should be insulated
with steam-resistant material
when installed inside a building
to prevent the formation of
condensate and ice. Sound
insulating measures may also
be necessary.
Ground water as heat source
Legend:
Fig. 8.20: Schematic representation of water-to-water heat pumps
Two wells are required for the
withdrawal of ground water, an
“extraction well” and an
“absorption well”. The
absorption well must in the
direction of ground water flow.
The underwater pump and
wellheads should have an
airtight seal.
