System and method of extracting water from atmospheric air

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.

We claim: 
     
         1 . 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.   
     
     
         2 . The system of  claim 1 , wherein water is simultaneously pumped and circulated through the pre-humidifier cooling pad from the third water tank, wherein the water circulation through the pre-humidifier cooling pad increases the humidity thereof and keeps the water cool at all-time. 
     
     
         3 . The system of  claim 1 , wherein the system generates pure drinking water from waste water using thermoelectric engine wherein to extract water from air using controlled thermoelectric based through an evaporative technology, the system further comprising:
 a. an enclosed surface comprising:
 i. at-least three tanks wherein the first tank is filled with non-potable water or waste water; 
 ii. a pre-humidifier cooling pad, wherein the pre-humidifier cooling pad is fed and pumped with the waste water from the first tank; 
 iii. a fan, wherein the fan sucks or draws the air through a louvre from the outside atmosphere and pass through the pre-humidifier cooling pad, wherein the pre-humidifier cooling pad creates more humid air inside the enclosed surface therein; 
 vi. a thermoelectric engine, wherein the thermoelectric engine is energized and thereby creates a hot side and a cold side; 
 v. a multi-flow condenser or multi-channel micro flow condenser with a closed loop water circulation connected to the cold side of the thermoelectric engine, wherein the multi-flow condenser having closed loop water circulation is exposed to the humid air to condensate the water content therein, wherein the condensed water is collected and stored in a second tank, wherein the air with reduced water content/drier air is further passed through a hot side management and radiator attached to the hot side of the thermoelectric engine to liberate the heat therein; and 
 vi. a water filter unit, wherein the water filter unit collects and purifies the condensed water from the second tank and passes the filtered water to a third tank for drinking purpose. 
   
     
     
         4 . The system of  claim 2 , wherein the system further comprises a fourth tank which is filled with the water and allows to flow towards the cold side of the thermoelectric engine continuously, wherein the outlet of the multi-flow condenser is first passed through third tank to make the drinking water more cool at all times, before connecting to fourth tank. 
     
     
         5 . The system of  claim 2 , wherein the system further comprises an air filter to filter the sucked or extracted air from the atmosphere. 
     
     
         6 . The system of  claim 2 , wherein the system is energized through various sources such as AC power and DC power, wherein the DC power is extracted through various sources but not limited to solar, battery or waste heat, etc. 
     
     
         7 . The system of  claim 2 , wherein the system generates more quantity of pure water by using less quantity of waste water by means of creating additional humidity thereby speeding up the condensation process. 
     
     
         8 . The system of  claim 2 , wherein the system further uses a humidity sensor to optimize waste water usage by using a control algorithm, wherein the control algorithm uses the inlet and outlet relative humidity (RH) values from the humid sensor to determine whether to turn ON or turn OFF the waste water pump to optimize waste water usage therein.
