Abstract: A system for compressing gas that changes ambient atmosphere conditions which uses a hermetic compressor, a condenser to receive compressed gas from the compressor and condense it, a liquid receiver to store the condensed gas, an expansion valve to vaporize the condensed gas and an evaporator which interacts with the ambient atmosphere. Isolating devices are used to isolate the compressor from the other parts of the system. A power invertor which changes the direct current to alternating current used with the isolating devices enable the use of a hermetic compressor in a direct current environment. Also included are cooling devices that use the cool internal vapor and the cool water formed on the outside of the evaporator to cool the compressor and its components.
