Insulation against condensation
Energy effective way for free cooling
Recharge the borehole during the summer
LK 322 CoolUnit is a valve combination that utilises the cold
available in a system with a geothermal heat pump.
By running the brine in the collector hose to a fan coil, you can
cool your home with the cold naturally found in the ground. In
addition, the borehole is recharged during the summer, which
increases the performance of the heat pump.
The LK 322 CoolUnit also contains a non-return valve to ensure
the liquid is run in the right direction when fitting the shunt
group with its own circulation pump. See LK HydronicGroup
C/C 90 and 125 Cooling for a suitable shunt group.
The LK 322 have two 1” alt. 11⁄4” male thread for connection to the
collector pipe. Two ball valves with 3⁄4” male thread for connection
to convector pipe.
