Abstract
When not only integrating the compressor and expander, but also the heat exchanger in one single rotor, a machine working according to the gas turbine process can be simplified. The gas turbine process in such a machine can also be run in reversed mode as a refrigeration machine or heat pump. Lower relative velocities between the working fluid and the components of the machine can be used which should lead to lower frictional losses and a higher efficiency. In order to further reduce the friction the rotor should rotate in a chamber with low pressure or in a medium with lower friction than air. The medium that exchanges heat with the working medium here called the heat carrying fluid is also taken into the rotor.
