<p><P>PROBLEM TO BE SOLVED: To provide a pressure-reduced dehydration method/water conversion method of easily generating domestic water or industrial water from seawater in a disaster or an emergency, or at ordinary times without using thermal energy so as to ensure security of water, the method including a second process of lowering atmospheric pressure of an atmosphere to generate unsaturated wet air from a water containing body, a third function for conversion into saturated wet air in a pressure-raised state, a fourth function of causing dew condensation to collect fresh water, and thereby eliminating the need for conventional thermal energy and eliminating a freezing process because of dew condensation. <P>SOLUTION: The fresh water and a dehydration product are separated and collected by sequentially repeating a first function of placing a water containing sample in an air atmosphere, a second function of reducing the pressure of the air atmosphere using a wing-shaped body of an airplane or a compressor to generate the unsaturated wet air, the third function of raising the pressure for conversion into the saturated wet air, and the fourth function of carrying out dew condensation and liquefaction on a hydrophilic dew condensation surface as a nucleus. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
