Seawater District Cooling (SDC) uses the cold deep seawater at 4°-8°C for cooling. The cold seawater is circulated through heat exchangers and replaces energy intensive chillers or cooling units, which allows for up to 90% energy savings.
Energy used in cooling of buildings in tropical areas accounts for over half of their energy demand. Energy use in these regions is subject to fluctuating energy prices based on fossil fuels. Seawater District Cooling provides an alternative to building owners close to the coast that want to have lower and stable and predictable operating costs.
