PURIFIED WATER-PRODUCING DEVICE AND PURIFIED WATER PRODUCTION METHOD USING SOLAR ENERGY

摘要

Disclosed is a purified water-producing device which simultaneously uses solar-thermal energy and solar-optical energy. The purified water-producing device according to the present invention comprises: a purified-water generating unit for making water vapour by evaporating sea water and making purified water by condensing the water vapour; a heating unit for supplying the purified water generating unit with the heat necessary to evaporate the sea water; a solar-thermal unit for absorbing the sun's heat and supplying heat to the heating unit; and a solar-optical unit for making electrical energy by absorbing sunlight, supplying the electrical energy to the heating unit and the purified-water generating unit, and supplying heat to the heating unit.
