Patent ID: 7631511

Claim:
A portable air conditioning and water-cooling unit that cools air and water simultaneously, said apparatus consisting of: a cart having wheels, a frame and a housing mounted on said wheels, a front support and a handle; a first opening and a second opening in said housing for allowing air into and out of said housing, a duct for directing hot air out of a room or area and a vent for releasing cooled air into the surrounding area; refrigeration means including a mass of R-22 refrigerant and a single hermetic rotary compressor having an inlet for compressing the refrigerant, a single condenser for condensing the refrigerant and a pipe connecting said compressor to said condenser so that compressed refrigerant flows out of said compressor and into said condenser to be condensed thereby; first and second capillary tubes and first and second connecting means, said first connecting means connecting said first capillary tube to said condenser for reducing pressure of the refrigerant and said second connecting means connecting said second capillary tube to said condenser for reducing pressure of said refrigerant therein; an air conditioning thin tube evaporator and third connecting means connecting said air conditioning thin tube evaporator to said first capillary tube for cooling air and wherein said air conditioning thin tube evaporator includes an outlet; a first pipe for connecting the outlet of said air conditioning thin tube evaporator to said inlet of said rotary compressor; a supply of water, a water cooling evaporator and fourth connecting means connecting said water cooling evaporator to said second capillary tube for receiving the refrigerant therefrom and for cooling water from said supply of water, and wherein said water cooling evaporator includes an outlet; a second pipe for connecting said outlet of said water cooling evaporator to said inlet of said rotary compressor; a first thermostat for sensing the temperature of water and a solenoid valve activated by said thermostat for stopping the flow of refrigerant to said second capillary tube to thereby direct all of the flow of the refrigerant to said first capillary tube when the supply of water reaches a pre-selected temperature; a second thermostat and means for shutting off said compressor when the surrounding air reaches a pre-selected temperature; a centrifugal blower fan for circulating air through the unit for cooling the air conditioning evaporator; and in which the water cooler evaporator is a shell and coil heat exchanger.
