EVACOLD heats incoming brackish (polluted) water to 50 °C and passes through an exchanger in which it is in contact with an incoming pre-heated air flow. The system generates two by-products: an air saturated with water, which can be condensed to generate distilled water, and dry salty residue that need to be handled properly. The energy required by EVACOLD to heat both incoming fluids (brackish water and air) is provided by: a) a photovoltaic solar panel which feeds a fan, the air cooling system and a set of small transfer pumps, and b) solar thermal panels which heat the incoming water to 50 °C, and the air up to the saturation point. In EVACOLD, there is no change between the liquid and vapor phases, so the energy consumption is minimal.
