Air conditioning system and transportation system including same

A transportation system, comprising:

• an electric motor;
• at least one element coupled to and configured to be driven by the electric motor in order to move the transportation system between an IDLING state corresponding to the transportation system being turned on and not moving, and an OPERATING state corresponding to the transportation system being turned on and moving;
• and
• an air conditioning system, comprising:
• an air compressor comprising an air compressor motor configured to pull in ambient air and generate pressurized air from the ambient air;
• a battery for powering the air compressor motor and the electric motor;
• a generator electrically connected to the battery;
• a blower;
• and
• a turboexpander comprising:
• a drive shaft coupled to the generator,
• a turbine wheel coupled to the drive shaft and fluidly coupled to the air compressor such that the pressurized air from the air compressor is configured to be forced through a conduit extending between the air compressor and the turbine wheel, and into the turbine wheel, thereby providing a source of kinetic energy to directly cause the turbine wheel to rotate and generate boosted air from the pressurized air, and
• an expander wheel coupled to the drive shaft and fluidly coupled to both the turbine wheel and the blower such that the boosted air from the turbine wheel is configured to be received in the expander wheel and directly cause the expander wheel and the drive shaft to rotate together with the turbine wheel, thereby generating expanded and cooled air in the expander wheel,
• wherein the turboexpander does not rotate due to a combustion reaction involving burning of fuel by an apparatus indirectly connected to the turboexpander via intermediate components,
• wherein the turboexpander does not rotate due to a combustion reaction involving burning of fuel by an apparatus directly connected to the turboexpander,
• wherein the expander wheel and the generator are configured to convert the source of kinetic energy to mechanical energy of the drive shaft, and then convert the mechanical energy of the drive shaft to electrical energy in the generator in order to generate electricity for charging the battery and thereby powering the air compressor motor and the electric motor, and
• wherein the blower is configured to receive the expanded and cooled air from the expander wheel and deliver the expanded and cooled air to an environment.
