A data center cooling system configured to cool one or more components of a data center thereby enabling a data center to be maintained at a higher overall temperature while still providing sufficient cooling to the components housed in the data center is disclosed. By maintaining the data center at a higher overall temperature, significant operational costs are realized due to savings in power costs. The data center cooling system may include one or more turbo-expanders having a rotary turbine positioned within a turbo-expander housing in which compressed air expands and drives the rotary turbine. The cooled expanded air is heated passing through a thermal transfer system that pulls heat from the data center component. The air is further heated passing through a brake system that generates heat by applying resistance to a shaft coupled to the rotary turbine. The heated air is exhausted outside of the data center.

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.

A system for cooling a hyperbaric chamber includes a compressor, a first hose, a cooling unit, a second hose, and a hyperbaric chamber. The first hose fluidly connects the compressor to the cooling unit, and the second hose fluidly connects the cooling units to the hyperbaric chamber. Compressed air from the compressor travels through a first pressure relief fitting and a second pressure relief fitting, where the compressed air is depressurized according to the system requirements. During the depressurization, the compressed air cools down because of the depressurization and creates a comfortable environment within the hyperbaric chamber.

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.
