An integrated air conditioning and power unit is provided for use with an aircraft. The system includes an air turbine 42 having air passages connected to an engine 10 of the aircraft for receiving bleed air and/or ram air for driving the air turbine 42. A motor/generator 104 is drivingly connected to the air turbine 42. The motor/generator 104 is capable of drawing electricity from an aircraft primary power system for driving the motor or generating electricity which is delivered to the primary power system 108. An air compressor 54 is drivingly connected to the motor/generator 104 and is provided with an air passage which receives bleed air 32 and/or ram air 30 from the aircraft engine 10. A cooling system 71 is provided including a system compressor 81 drivingly connected to the motor/generator 104. A cooling system evaporator 70 and a condenser 92 are connected to the system compressor by fluid passages. The air compressor 54 includes an air outlet for providing pressurized air which is cooled by the cooling system.
