1 Area of use
For cooling requirements greater than can be obtained only
through passive cooling (free cooling).
For cooling requirements at max. 20 kW.
The cooling module makes it possible to retain passive or passive/
active cooling from the rock –groundwater collectors. The distribu-
tion system for this can be the radiator system (fan convectors) or
under floor heating systems. Cooling starts when the outside tem-
perature exceeds the set value for heat stop.
2.1 For the installer
2.1.1 Pipe installation
The cooling module must be mounted hanging vertically on a wall.
The central distance for mounting holes is 530 mm.
Pipe installation is carried out according to the wiring diagrams
found on page 8-13.
Installation must be carried out under the supervision of an autho-
rised electrician.
Function during cooling operation
Stage 1. Passive cooling
In order for the heat pump to start passive cooling, the following
conditions must be fulfilled:
1. The outside temperature is higher than the setting for heat
stop.
2. Room temperature exceeds the desired temperature by the
same amount of degrees that the room factor is set to.
3. The above requirements must be met within 5 minutes.
The heat pump’s internal brine pump starts and circulates the coo-
lant via the cooling module to the bore hole. In the cooling module,
the set temperature is shunted out to the cooling system
530 mm
Stage 2. passive/active cooling (this function are only available
on the passive/active module)
In order for the heat pump to start passive cooling, the following
conditions must be fulfilled:
1. All conditions for passive cooling must be fulfilled.
2. Room temperature exceeds the desired temperature by twice
the room factor.
3. The above requirements must be met for 1 minute.
4. If the in coolant temperature exceeds the desired temperature
to the cooling system during passive cooling, active cooling is
force connected after 120 seconds
The heat pump’s compressor starts and the shift valves for active
cooling operation are reset. In the first instance, the excess heat is
used, which is produced in the heat pump’s condenser for hot water
heating. When the hot water is heated, the excess heat is shifted
down to the bore hole. This provides more favourable operation for
the heat pump at the same time as a high cooling effect and good
efficiency is achieved.
