4.7.1 Free cooling
An independently operating cooling system can be connected to the heat pump’s brine
circuit.
A circulation pump draws cool brine from the brine circuit and pumps it through a
cooling circuit. As the brine passes through the circuit, heat is extracted from indoor air.
After the cooling circuit, the brine is fed back into the brine circuit.
If the system includes an optional room temperature sensor, the system will
automatically adjust room temperature to the desired level. If there is no room
temperature sensor, the system will always run at full capacity.
Free cooling is an energy-efficient and economical method for cooling spaces, since
electricity is required only for running the circulation pump and cooling unit fans.
There are three operating modes for free cooling: Room temperature control, External
control, and Manual control. The control mode is determined during commissioning in
the Maintenance menu.
Room temperature control
The
Cooling - Targets temperature
view allows you to specify the indoor temperature
range within which the cooling system will be operational.
● Set the minimum and maximum value by tapping each value’s field.
Cooling - targets temperature ver. 1
Additionally, the view shows the current room temperature, the current brine
temperature ( Liquid ), air moisture level, and dew point. The current operating mode
( State ) is also shown.
External control
In the External control mode, the cooling system will be controlled by an external
thermostat. This thermostat needs to be installed and adjusted by the installation
company as specified in the wiring diagrams supplied with the unit.
