Title: Distilling plant
Inventor: YAMADA SHINICHIRO
IPC: E03B3/28
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To implement a distilling plant which achieves high distilling efficiency in a desert zone. SOLUTION: The distilling plant 25 is constituted of a condenser 2, an evaporator 3, a blower 5, and a drain pan 7, and it is set in a storage house 30. Outside air enters the storage house 30 from an air intake port 36, and flows from an air suction port 6 into the distilling plant 25 to be cooled in the evaporator 3. Thus, moisture in air is condensed, deposited on the evaporator 3, and then dropped on the drain pan 7. Therefore, by collecting the dropped moisture, water can be obtained. The condenser 2 is set on a downstream side of the evaporator along the flow of outside air. As a result, the condenser 2 is cooled by air cooled by the evaporator 3, and therefore refrigerant gas in the condenser 2 can be sufficiently cooled, to thereby enhance the distilling efficiency in the evaporator 3.
