PURPOSE: A desalination method for evaporating and condensing vapor by using temperature difference of air heat and sweater heat are provided to produce fresh water with minimized energy, and to produce vapor in an evaporation pipe. CONSTITUTION: A desalination method for evaporating and condensing vapor includes the following steps: filling a cast iron pipe(2) with water; connecting a condensation pipe to an evaporation pipe which is formed on the top of the pipe; transferring vapor produced in the evaporation pipe to a heat-exchange pipe of a second evaporation pipe(3); heat-exchanging water to the evaporation pipe, and penetrating the heat-exchange pipe to a first evaporation pipe(1); and condensing the water in the evaporation pipe. |
