Electric air conditioning system for an aircraft

An aircraft comprising:

• a fuselage defining an interior volume;
• an air conditioning system coupled to said fuselage, said air conditioning system being operable to output conditioned air to said interior volume;
• and
• a cabin air recovery system coupled to said air conditioning system, said cabin air recovery system being operable to direct at least a portion of said conditioned air from said interior volume back to said air conditioning system for further conditioning;
• a second compressor fluidly coupled to said first compressor, said second compressor being operable to compress said conditioned air from said first compressor;
• and
• a second electrical motor driving said second compressor.

An aircraft comprising:

• a fuselage defining an interior volume, said interior volume having conditioned air at a first pressure;
• a first compressor operable to compress supply air to a second pressure;
• a first electrical motor driving said first compressor;
• a passage fluidly coupling said first compressor and said interior volume;
• a heat dissipating device positioned in said passage, said heat dissipating device operable to extract heat energy from said supply air;
• and
• a conditioned air recovery system coupled to at least one of said first compressor and said heat dissipating device, said conditioned air recovery system being operable to direct at least a portion of said conditioned air from said interior volume to be mixed with said supply air;
• a second compressor fluidly coupled to said first compressor, said second compressor being operable to compress said supply air from said first compressor;
• a first turbine operably coupled to one of said first compressor and said second compressor;
• and
• a second electrical motor driving said second compressor.
