METHOD AND APPARATUS FOR REGENERATING WATER

Document Type and Number:

WIPO Patent Application WO/2005/052369

Kind Code:

A1

Abstract:

A method for regenerating water which comprises heating the ice formed on the portion in a vessel having an extremely low temperature refrigerator installed therein which portion is cooled by said extremely low temperature refrigerator to a temperature above the melting point thereof to melt it, exposing the resulting water to a reduced pressure by rough evacuation to evaporate water, and immediately after the discharge of the evaporated water, further reducing the pressure to discharge water vapor. The method allows the regeneration of water conforming to the state (solid, liquid or gas) of water, which results in the shortening of the time required for the regeneration.
