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.
