The buildings are supplied with usable cold for air conditioning from a refrigeration plant. Cold water is used as a cooling medium and is usually distributed to one or more customers via a refrigeration network.
LuxEnergie uses two types of chillers to generate cold:
This technology uses only electricity as an energy source.
Besides the low electricity demand, absorption refrigerators mainly use heat as primary energy. This process uses the thermal and physical properties of a solution of water and salt.
