ABSTRACT:
A portable air conditioning and water-cooling unit includes a mass of refrigerant and a compressor for compressing the refrigerant. The unit also includes a single condenser for condensing the refrigerant and a pipe connecting the compressor and condenser. First and second capillary tubes and first and second connectors connect the first capillary tube to the condenser and a second connector connects the second capillary tube to the condenser. In addition, the unit includes an air conditioning evaporator and a pipe for connecting the air conditioning evaporator to the first capillary tube for cooling air. A water supply is also provided as well as a water-cooling evaporator and pipe connecting the water-cooling evaporator to the second capillary tube. A first thermostat senses the temperature of the water and sends a signal to a solenoid valve for stopping the flow of refrigerant to the second capillary tube when the water reaches a pre-selected temperature. The entire cooling load is directed to the A/C evaporator when the surrounding area reaches a pre-selected temperature. A second thermostat sends a signal to the compressor to shut it off.
