Abstract
Novel vapor compression evaporative cooling systems which use water as a refrigerant are provided, as are methods for using same. Also provided are novel compressors, compressor components, and means for removing noncondensibles useful in such cooling systems.
Claims48
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.
