Open cycle cooling system

A cooling system, comprising:

• a source of liquid natural refrigerant;
• a heat exchanger in communication with the source of liquid natural refrigerant that is configured to receive the liquid natural refrigerant at a first temperature and at a first pressure, convert the liquid natural refrigerant into a gaseous natural refrigerant, and discharge the gaseous natural refrigerant at the first temperature and the first pressure;
• a compressor in communication with the heat exchanger and configured to increase the first temperature and the first pressure of the gaseous natural refrigerant received from the heat exchanger to a second temperature and a second pressure;
• 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,
• wherein 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.
