Abstract
Disclosed is a system to extract water from air using a thermoelectric technology/vapor compression cycle with a combined evaporative cooling. The system extracts high quantity of water by creating more humid air inside the enclosed surface using a pre-humidifier cooling pad. Further, the system consumes less time and energy to extract the water in both hot and dry climates. Further, the system includes a condenser, wherein the condenser temperature does not increase more than 37.8 degree Celsius. Further, the system uses hot side management technology to cool the water and uses the water to reduce the condenser temperature therein. Further, mineral deposited waste Reverse Osmosis (RO) water is collected and may be sold to chemical laboratories for further use.
Claims8
A system of extracting water from atmospheric air with dehumidification and cooling using thermoelectric based/vapor compression cycle combined with evaporative cooling technology, the system comprises:
- i. a compressor to compress the gases to high pressure and temperature therein;
- ii. a condenser to receive and convert the gases into a liquid at high pressure and temperature;
- iii. a first water tank with at least one pump, wherein the first water tank is filled with non-potable/Reverse Osmosis (RO) waste water, wherein the pump inside the first water tank pumps the non-potable/RO water to a sprinkler, wherein the sprinkler allows the non-potable/RO water to flow on top of the condenser, wherein the water flow controls and manages the temperature inside the condenser below 37.8 degree Celsius;
- iv. an expansion valve to expand and decrease the high-pressure liquid to a low-pressure liquid at lower temperature;
- v. an evaporative coil to receive and convert the low-pressure liquid into a vapor at lower temperature and fed back to the compressor and thereby constituting the controlled vapor compression cycle;
- vi. a hot side management cooling pad, wherein the hot side management cooling pad is fed and pumped with non-potable/RO water from the first water tank, wherein the hot side management cooling pad lowers/cools the water (removes the heat gained from the condenser and creates more humid air before passing through the condenser,
- vii. a fan to dissipate the hot dry air from the condenser, during the vaporization cycle.
