Seawater Air Conditioning

How it works: (1) Cold water is extracted from the deep ocean, (2) sent to a heat exchanger that (3) chills fresh water circulated to customers [no seawater is sent to customers] and (4) connected with their existing AC system. (5) The slightly warmed seawater is returned to the ocean in an environmentally safe manner.

Why Seawater Air Conditioning?

SWAC doesn’t actually produce power, but rather provides a firm and reliable air conditioning source for commercial customers. Since air conditioning is responsible for 40% of power consumed in parts of Oahu, SWAC proves to be a valuable asset to reduce cost of air conditioning and peak power demand. The infrastructure of SWAC is hidden below surface grade with existing utility infrastructure and customer’s mechanical spaces.
