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 an air passage duct that provides an air circulation pattern driven by a fan or similar device. The circulating air undergoes cooling to a temperature below the dew point to collect water from the air. The collected water is stored in a principal storage vessel where ozone is injected to eliminate bacteria and contaminants. At least a portion of the recovered water is transferred to a secondary storage vessel where it is further cooled by refrigerant from the same compressor.

Abstract: An apparatus and method for condensing water vapor in air to extract liquid water in which a refrigeration system defines a closed-loop refrigerant path. The refrigeration system includes a main portion, a first branch portion and a second branch portion. The first branch portion and the second branch portion each have an entrance and an exit in fluid communication with the main portion. The first branch portion includes a first evaporator operable at a temperature of at most a dew point of air contacting the first evaporator to cause liquid water to condense on an exterior surface of the first evaporator. The second branch portion includes a second evaporator. A first water vessel is positioned proximate to the first evaporator for collecting water from the exterior surface of the first evaporator. A second water vessel is positioned proximate to the second evaporator for holding water chilled by the second evaporator. A conduit transports water from the first water vessel to the second water vessel.

Abstract: An apparatus and method for extracting water from air in which a refrigeration system includes a cooling element to condense water from air. A first water vessel defines an inner volume. The first water vessel stores the water collected from the cooling element. An ozone device generates ozone inside the inner volume of the first water vessel. The ozone device provides the ozone to the water to resist bacteria and contaminants.

Abstract: An apparatus and method for condensing water vapor in air to extract liquid water includes an air duct, an air movement device, and a refrigeration system. The air duct has an entry port, an intermediate port, and an exit port; while the refrigeration system includes at least one evaporator and condenser within the air duct. The air movement device may be a fan within the air duct, to cause air flow through the condenser and out the exit port. The air has a dew point, and the evaporator temperature is at that dew point or less, to cause liquid water to condense on the evaporator's exterior surface. The intermediate port of the air duct is between the evaporator and condenser, such that air can enter the air duct by at least two paths: through the entry port and evaporator, and through the intermediate port which bypasses the evaporator.

Abstract: An apparatus and method for condensing water vapor in air to extract liquid water includes a refrigeration system having a cooling element and a refrigerant sub-cooler. The refrigeration system may have a cooling element with an exterior cooling surface over which air passes to shed heat and reach a lower temperature. The air has a dew point, and the cooling surface is at that dew point or less, causing liquid water to condense on the cooling element. The resulting liquid water may be caught in a water basin. The sub-cooler is immersed in liquid water collected in the water basin, to shed heat from refrigerant inside the sub-cooler.
