Deep Sea Cooling - District Cooling basics
DistrictCooling is based on central production of cold water which is distributed to customers in a closed loop pipe network. Production can be based on
various sources and technologies.
Common natural sources are seas, lakes, rivers and ground water. Where excess heat from industrial or energy production is available, absorption chillers
can be used t0 produce cooling.
Day and night storage of cold water or ice can help increase efficiency and lower cost.
At the customer end of the system, the cooling is transferred to buildings in energy transfer stations (ETS).

Deep-Sea water-cooling systems are much less exposed to future volatile energy prices for gas, power
and water due to its low operating (variable) cost and dependency of such services
