Abstract: An air conditioning system is provided. The air conditioning system includes a turboexpander. The turboexpander includes a drive shaft, a compressor wheel coupled to the drive shaft and configured to rotate together with the drive shaft, and an expander wheel fluidly coupled to the compressor wheel in order to allow air to flow from the compressor wheel into the expander wheel. The expander wheel is coupled to the drive shaft and configured to rotate together with the compressor wheel. The compressor wheel is configured to compress the air, and the expander wheel is configured to expand the air.

Abstract: An air conditioning system is provided. The air conditioning system includes an air compressor configured to pull in ambient air and pressurize the ambient air in order to generate pressurized air, and a coolant-free expansion apparatus fluidly coupled to the air compressor and configured to receive the pressurized air and convert the pressurized air into expanded and cooled air for delivery to an environment.

Abstract: An air conditioning system is provided. The air conditioning system includes an air compressor, a battery, a generator, a blower, and a turboexpander. The air compressor generates pressurized air from ambient air. The battery is for powering the air compressor motor. The generator is electrically connected to the battery. The turboexpander includes a drive shaft, a turbine wheel coupled to the drive shaft, and an expander coupled to the drive shaft. The pressurized air provides a source of kinetic energy to directly cause the turbine wheel to rotate and generate boosted air from the pressurized air, and 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.

Abstract: An air conditioning system includes a rotation driving device, an energy storage device for powering the rotation driving device, a generator electrically connected to the energy storage device, and a turboexpander. The turboexpander includes a drive shaft coupled to both the generator and the rotation driving device, and configured to be rotated by the rotation driving device. The turboexpander also includes a compressor wheel and an expander wheel. The compressor wheel is configured to pull in ambient air and generate pressurized air from the ambient air responsive to rotation of the drive shaft. The expander wheel is fluidly coupled to the compressor wheel such that the pressurized air from the compressor wheel is configured to be received in the expander wheel and converted into expanded and cooled air by the expander wheel for delivery to an environment.
