Sea Water Air Conditioning SWAC

Using the low-temperature of oceans to decrease ac energy needs

Identification

In tropical environments especially, demand for air conditioning is high all year round. This typically comes at a high energy cost, which is in turn typically produced from non-renewable sources. In certain industries and buildings, such as hotels for tourism or hospitals for healthcare, air-conditioning is frequently the largest single usage of energy, representing up to 40% of total consumption. This solution aims to drastically reduce the amount of energy consumed to produce air conditioning while using a renewable natural source of cold. The solution could be implemented anywhere with suitable bathymetry and easy access to deep ocean water and strong AC needs. The concept of the solution is to give the opportunity to have cool air when needed, while considerably decreasing the energy consumption and our carbon footprint. The solution is a Sea Water Air Conditioning (SWAC) system. This system permits to save about 42% of energy comparing to a conventional AC system. It uses the temperature of the deep ocean to cool an AC loop, releasing seawater back to the ocean with no impact. This solution sends a 2,6km piping into the ocean to reach a 930m deep area. The impact on the environment is very low and safe - It provides air conditioning using the cold of the deep ocean.
