Abstract:
A vapor-compression evaporative air conditioning system comprising:an evaporator; a room air contactor for directly exchanging heat between room air and a quantity of water from said evaporator; a positive displacement compressor for compressing a volume of water vapor, thereby creating a vacuum on said water in said evaporator, said compressor comprising an inlet and an outlet, wherein low-pressure water vapors from said evaporator enter said inlet and compressed water vapors exit said outlet; a condenser for receiving said compressed water vapors from said compressor; means for reducing a water content of said vapors exiting the condenser; means for removing noncondensibles from said condenser; and an ambient air contactor for directly exchanging heat between the ambient air and water from said condenser.
