A system and method of altering the air conditioning system in an aircraft so that the air conditioning system is electrically powered rather than engine powered. The aircraft is rid of the air conditioning components that are dedicated to the engine powered system. A new electric compressor, evaporator and condenser blower assembly are then installed. Heat exchanger units are installed in the areas of the aircraft that are to be cooled. The new air conditioning system has two circulatory loops. In a refrigerant loop, refrigerant is circulated between the electric compressor, evaporator and condenser. This cools the evaporator. The evaporator is then used to cool circulating liquid coolant. The coolant is circulated to the heat exchange units.

1. In an aircraft having pressurized compartment containing passenger seats adjacent a center isle, overhead panels above the passenger seats, and an accessible compartment below the center isle, wherein the aircraft has an air conditioning system with a condenser and a mechanically driven compressor, and wherein said mechanically driven compressor is driven by an engine of said aircraft, a method of reconfiguring said air conditioning system, comprising the steps of: removing said mechanically driven compressor;installing an electric compressor into said accessible compartment under said center isle of said aircraft;installing an evaporator into said accessible compartment under said center isle of said aircraft;circulating refrigerant between said electric compressor, said condenser and said evaporator, wherein said refrigerant cools said evaporator;installing heat exchanger units within said overhead panels above said passenger seats of said aircraft;running tubing in said aircraft between said heat exchanger units and said evaporator;circulating liquid coolant between said heat exchanger units and said evaporator, wherein said liquid coolant is cooled by said evaporator. 2. The method according to claim 1 further including the step of installing at least one pump in said aircraft to pump said coolant through said tubing, wherein said at least one pump is installed in said accessible compartment under said center isle of said aircraft. 3. The method according to claim 1, further including the step of installing an electric blower assembly in said aircraft proximate said condenser. 4. The method according to claim 1, further including the step of providing a connector port for receiving electricity from an external power cord that can be used to power said electric compressor. 5. The method according to claim 4, further including the step of providing a power control unit that conditions electricity received through said connector port. 6. The method according to claim 1, wherein said aircraft has an exterior fuselage and an interior wall, wherein said step of running tubing includes running tubing between said exterior fuselage and said interior wall. 7. In an aircraft having a pressurized compartment and an air conditioning system for cooling areas within said pressurized compartment, wherein said air conditioning system has an engine-driven compressor, a method of reconfiguring said air conditioning system, comprising the steps of: removing said engine-driven compressor;installing heat exchanger units within said pressurized compartment;installing a coolant circulation system that circulates coolant to said heat exchanger units;installing an electrically powered refrigeration system for cooling said coolant as it circulates, wherein said electrically powered refrigeration system includes an electric compressor and an evaporator that are both disposed within said pressurized compartment of said aircraft. 8. The method according to claim 7, wherein said aircraft has a condenser, wherein said electrically powered refrigeration system circulates refrigerant between said electric compressor, said evaporator and said condenser. 9. The method according to claim 7, wherein said step of installing a coolant circulation system includes the substep of running flexible tubing in said aircraft between said heat exchanger units and said evaporator. 10. The method according to claim 9, wherein said step of installing a coolant circulation system includes the substep of installing at least one pump in said aircraft to pump said coolant through said flexible tubing. 11. The method according to claim 8, further including the step of installing an electric blower assembly in said aircraft proximate said condenser. 12. The method according to claim 7, further including the step of providing a connector port for receiving electricity from an external power cord that can be used to power said electric compressor. 13. The method according to claim 7, wherein said aircraft has overhead panels and said step of installing heat exchanger units includes installing some of said heat exchanger units in said overhead panels. 14. The method according to claim 7, wherein said aircraft has a passenger isle and a compartment under said passenger isle, wherein said electric compressor and said evaporator are installed within said compartment.
