ABSTRACT:
The present invention comprises an apparatus for obtaining potable water from the ambient air. A compressor (16) is provided for compressing a refrigerant. A condenser (18) is provided for condensing the refrigerant received from the compressor (16). An evaporator coil (14) is provided for receiving at one end thereof compressed refrigerant from the condenser (18) and being disposed in a water tank (12). The evaporator (14) is operable for evaporating refrigerant and thereby cooling the potable water (13) in the water tank (12). Drip coils (28) are provided for condensing the potable water from the ambient air with the cooled potable water (13) from the water tank passing through the drip coils (28) before returning to the water tank (12). A fan (20) is provided for blowing ambient air about the drip coils(28) and the condenser (18). A discharge device (44) is provided and is connected to the drip coil (28) and a pump (27) is provided for pumping water through the drip coils (28) and the discharge device (44). A filter (40) and ultra-violet light source (42) are provided for sterilizing the potable water (13) and a non-toxic coating is provided and disposed on the interior of the drip coil (28) and the exterior of the evaporator (14), with the non-toxic coating comprising 25 to 35 percent titanium oxide.
