Sea Water Air Conditioning

Seawater Air Conditioning (SWAC) takes advantage of available deep cold water from the ocean, a river, or lake, to replace conventional AC systems. Such a system can also utilize cold lake or river water as the cold source.

SWAC feasibility studies for a variety of sites indicate that electrical consumption is typically reduced by 80 to 90 percent. Simple payback can be from three to seven years, and long term costs can be half that of a conventional air conditioning system.
