Patent ID: 7093455

Claim:
A method for cooling air comprising the steps of: compressing a large volume of low-pressure water vapor with a compressor, thereby creating a vacuum on a quantity of water in an evaporator and causing evaporation and said water to be cooled; pumping cooled water from said evaporator and contacting said cooled water countercurrently with room air in a room air contactor, thereby cooling room air; routing water from said room air contactor to said evaporator, causing said water to flash and cool; sending compressed water vapors exiting the compressor to a condenser for condensation; countercurrently directly contacting said water vapors exiting the condenser with a stream of chilled water from said evaporator to reduce the water content from air; removing noncondensibles from said condenser; routing liquid water from the condenser to an ambient-air contactor, where ambient air is contacted countercurrently with liquid water pumped from the condenser; providing make-up water to replace evaporated water; and draining salt water.
