Abstract
A gas cycle cooling system having a rotary compressor and expander driven by a common shaft wherein the compression and expansion of a modified reverse Brayton cycle is provided within a closed chamber by changes in volume brought about by vanes sliding within slots in a rotor. The rotor is positioned within the chamber to provide spaces between the rotor and the chamber wall which act as effective gas transfer passages between the compressor and the expander. Liquid from a first heat exchanger is circulated through the wall of the rotor housing adjacent the compressor portion of the chamber to remove heat during the compressor phase of the cycle. Liquid is circulated through the wall of the rotor housing adjacent the expander portion of the chamber to provide cooling for a second heat exchanger.
