Seawater air conditioning(SWAC) is an alternate energy system that uses the cold water from the deep ocean (and in some cases a deep lake) to cool buildings. In some areas it is possible to reduce dramatically the power consumed by air conditioning systems; SWAC can be cost effective and attractive investment. it is an alternate energy for air conditioning.

Benefits of SWAC system:

The seawater air condition systems taps into a significant and highly valuable natural energy resource that is available at some coastal locations. The benefits of a seawater air conditioning system include:

1. Large energy saving approaching 90%.

2. Proven technology

3. Short economic payback period.

4. Environmentally friendly.

5. Costs are nearly independent of future energy prices increases.

6. No evaporation water consumption.

7. Cold seawater availability for secondary applications.
