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 90C for a suitable shunt group. The LK 322 have two 1”- 1¼” male thread for connection to the collector pipe.
Two ball valves with 3/4” male thread for connection to convector pipe.
When fitting, use the wrench flats on the t-pipe coupling to prevent damage to the glued joint between the t-pipe coupling and the non-return valve.
