The present invention is directed to a water making device that collects the moisture contained in the atmosphere and condenses it into high purity water. In one embodiment, moist air entering the water making/water cooling system flows across an air filter, then a precooler heat exchanger (where the air stream is cooled to or close to its dew point) and then a water extraction heat exchanger, where the air stream is cooled further and water is extracted. The water that leaves water extraction heat exchanger is collected in a water collection device and passes from there through a primary water filter into a water storage tank. The air stream then passes across a reheat heat exchanger and exhausted to the outside. A water circulation pump extracts water from the water storage tank and circulates the water stream through an evaporator of a vapor compression refrigeration system, where the water stream is chilled, then through the water extraction heat exchanger and precooler, where the incoming air stream is chilled by removing heat to the water stream. The water stream is then circulated through the reheat heat exchanger, where the water stream is again cooled by removing heat to the cool dry air exiting the water extraction heat exchanger. Finally, the cooled water stream is circulated through the water filter to a three way valve, that directs water flow either to a dispenser or back to the water storage tank.

What is claimed is: 1. A device for collecting water from air, comprising: a housing, wherein a bottom of said housing comprises a first compartment and a second compartment; a precooler heat exchanger, disposed within said housing that receives an air stream, wherein said air stream is cooled close to its dew point by said precooler heat exchanger; a water extraction heat exchanger, disposed within said housing adjacent said precooler heat exchanger, wherein said water extraction heat exchanger further cools said air stream and extracts water therefrom; a condensed water collection device, disposed adjacent to said water extraction heat exchanger that collects said extracted water; a water storage tank, disposed in said first compartment of said housing, wherein said water is directed by said condensed water collection device into said water storage tank; a reheat heat exchanger, disposed within said housing adjacent to said water extraction heat exchanger, wherein said air stream is heated by said reheat heat exchanger; an exhaust outlet in said housing that permits said air stream to exit said housing; a fan disposed within said housing that establishes the flow of said air stream into said housing through said precooler heat exchanger and out of said housing through said exhaust outlet; a closed loop refrigerant circuit connecting a condenser and an evaporator through which a refrigerant flows from said condenser through an expansion valve to said evaporator and from said evaporator through a compressor into said condenser, wherein said closed looped refrigerant circuit is disposed in said second compartment of said housing; and a closed loop water circulation circuit through which a water stream is extracted from said water storage tank by a water circulation pump and flows to said evaporator, wherein said water stream is chilled, and said water stream flows from said evaporator through said water extraction heat exchanger, said precooler heat exchanger, and said reheat heat exchanger, to said water storage tank.
