The International Institute for Applied Systems Analysis writes on Tech Explore that seawater air-conditioning (SWAC) is an emerging renewable alternative to traditional air conditioning.
- SWAC is more feasible for island nations who are closer to deeper oceans.
- SWAC uses cool water from deep ocean depths to provide cool air for homes and buildings.
- This method of air conditioning has higher initial costs than traditional AC but has lower energy costs than conventional methods.
“Conventional air-conditioning (AC) is the most common technology used for cooling and represents a considerable share of energy demand in warmer regions. An alternative that is not frequently considered, is seawater air-conditioning (SWAC)—a renewable alternative for cooling that involves pumping seawater from ocean depths of around 700 to 1200 meters and temperatures of 3°C to 5°C to the coast, where it exchanges heat with a district cooling system, and returns the warmer water to the ocean.”
