ABSTRACT:
Apparatus and methods for transforming water vapor into potable water by using a vapor compression refrigeration system which includes first and second cooling elements disposed in a closed loop air passage duct that provides a continuous air circulation pattern driven by a fan or similar device. Water is introduced into the circulating air and undergoes adiabatic cooling followed by two stage cooling, first at a temperature below the dew point and then at a lower temperature at or below freezing. Water is collected from the air in each step and the air is thereafter heated back up by the condensing element of the refrigeration system enabling it to absorb more water vapor at the point of introduction. The air is recirculated and processed as above to permit cyclical water recovery.
