The heat pump system consists of the following components:
–
Heat pump
(1)
–
System control
(2)
(from VRC 700)
–
Outdoor temperature sensor with DCF receiver
–
System sensor, if required
–
With ground heat source: Ground collector
(3)
–
With well water heat source: Ground water module
(4)
The heat pump system generates heat for heating installa-
tions and in domestic hot water generation by extracting the
thermal energy from a heat source circuit and releasing this
into the heating circuit via the internal refrigerant circuit. The
heat pump can be connected to two different types of heat
source (geothermal energy and ground water with a transfer
station between them). At the same time, there is an oppor-
tunity for active cooling to take place via circulation reversal.
3.1.1
Heat pump
–
Fulfils the heating demand of the system control down to
a minimum outdoor temperature and up to a maximum
target flow temperature.
–
Fulfils the cooling demands of the system control up to a
maximum source temperature.
–
Domestic hot water generation with external domestic hot
water cylinder
3.1.2
Ground water module
Heat transfer from the ground water to the brine heat transfer
medium in the heat pump.
3.1.3
Passive cooling module (optional)
When using ground or ground water as a heat source, the
heat of the heating water is transferred to the heat source
medium purely using circulation pumps and valve switching.
