System overview

3.1

Heat pump system design

A
B
The heat pump system consists of the following components:
–
Heat pump
–
System controller (from VRC 700)
–
Outside temperature sensor with DCF receiver
0020213395_00 flexoTHERM exclusive Installation and maintenance instructions
–
System sensor, if required
–
With ground heat source: Ground sensor
–
With well water heat source: Groundwater module
The heat pump system generates heat for heating installa-
tions and in hot water generation by extracting the thermal
energy from a heat source circuit and releasing this into
the heating circuit via the internal refrigeration circuit. At the
same time, there is an opportunity for active cooling to take
place via circulation reversal. The heat pump can be connec-
ted to two different types of heat source. This includes geo-
thermal energy and groundwater, whereby the heat source is
connected to the heat pump via a transfer station connected
between the two.
3.1.1
–
Fulfils the heating demand of the system controller down
to a minimum outside temperature and up to a maximum
target flow temperature.
–
Fulfils the cooling requirements of the system controller
up to a maximum source temperature.
–
Hot water generation with external domestic hot water
cylinder
3.1.2
–
Heat transfer from the groundwater to the brine heat
transfer medium in the heat pump.
3.1.3
–
When using ground or groundwater as a heat source,
the heat of the heating water is transferred to the heat
source medium purely using circulation pumps and valve
switching.
