Abstract
A cooling system that may include a source of liquid natural refrigerant, a heat exchanger in communication with the source of liquid natural refrigerant that is configured to convert the liquid natural refrigerant into a gaseous natural refrigerant, a compressor in communication with the heat exchanger and configured to increase a temperature and pressure of the gaseous natural refrigerant received from the heat exchanger, and an exhaust device in communication with the compressor and configured to expel the gaseous natural refrigerant received from the compressor to air of an external ambient environment. The exhaust device includes a membrane that permits the gaseous natural refrigerant to exit the exhaust device while preventing or at least minimizing the air of the external ambient environment from entering the exhaust device.
