The passive cooling module (NIBE PKM) consists of a compact unit with integrated separation heat exchanger, circulation pump as well as regulating valves.
NIBE PKM makes the passive cooling possible for a building over a suitable "surface heating" (floor, winding or ceiling heating) or a fancoils. The brine water circle is running separately from the cool and/or heating circle. PKM can cool if necessary and at the same time and prepare warm industrial water.
The integrated circulation pump is only used if the free cooling is used. There to the electrical cooling energy needed, only the driving power of the circulation pumps. Therefore the system works with high energy-saving and environmental friendly. For free / passive cooling by the use of brine or groundwater systems is the suitable warming and/or cooling source.
The brine can feed the energy entry into the soil and provides in such a way for an optimal energy use in the cooling.
