Abstract
A compressor includes a rotor having an outer compression surface and a plurality of inner heat exchange surfaces. A coolant supply manifold fluidly connects with a coolant inlet in a first axial end of the rotor, and delivers coolant fluid by way of conduits having an axial distribution in the rotor so as to deliver coolant fluid to the heat exchange surfaces. The coolant may be a refrigerant that undergoes a phase change within the rotor.
