Seawater Air Conditioning (SWAC) works by replacing the energy intensive electrical air conditioning system of a building or a group of buildings directly with the cold water from the deeper ocean. The cold seawater is fed through a heat exchanger that cools the fresh water of the air-conditioning for buildings, or other facilities.
Taking advantage of available cold deep seawater for air conditioning enables significant energy savings up to 90%. Therefore, SWAC is a very attractive technology with a high capital ROI.
SWAC gives utilities the possibility to offer a new product to their customers. Cooling can be distributed and metered to individual users via district cooling systems.
SWAC is not technically complex nor does it involve a high technical risk. It is established technology being applied in an innovative way. All the components necessary exist and have been operated under the conditions required.
