A closed loop air conditioning system for an aircraft includes a compressor stage including at least one power driven compressor, for compressing working fluid, a first expansion turbine over which compressed working fluid is expanded and cooled, a first heat load heat exchanger in which heat from a first heat load is exchanged to the expanded and cooled working fluid, a second expansion turbine over which working fluid from the first heat exchanger is further expanded and cooled, and a second heat load heat exchanger in which heat from a second heat load is exchanged to the further expanded and cooled working fluid.
