ABSTRACT:
An air conditioner system has a boiler for generating a refrigerant vapor from a liquid refrigerant therein and a condenser for condensing the refrigerant vapor to the liquid refrigerant. An expander connects the boiler and the condenser to generate output energy when the refrigerant vapor passes therethrough from the boiler to the condenser in a first direction. A fan produces an ambient air flow through the boiler and the condenser to provide heat input for vaporizing the liquid refrigerant in the boiler and cooling the air flow and for extracting heat from the condenser to condense the refrigerant vapor to the liquid refrigerant. A water mist is generated that contacts the air flow intermediate the boiler and the condenser for further cooling the air flow through heat of vaporization of the water so that air exiting the condenser is cooler than the ambient air flow entering the boiler. The further cooling of the air flow produces air at a temperature effective to condense the refrigerant vapor flowing in the first direction at a rate that produces a pressure differential between the boiler and the condenser that results in sufficient kinetic energy in the refrigerant vapor passing through the expander to produce a net surplus of output energy.
