Classification: CPC F  Y | IPC F

Claim 12:
13. A thermodynamic apparatus comprising:
a compressor module;
a turbine module; and
a regenerative heat exchanger;
wherein each of the compressor module, turbine module, and regenerative heat exchanger are centered on a central axis, and arranged in series along the central axis such that the regenerative heat exchanger is provided between the compressor module and the turbine module;
wherein the compressor module comprises:
a first heat exchanger and a compressor module rotor, each provided in a working fluid flow duct, the first heat exchanger provided in flow series between a compressor module inlet and the compressor module rotor, and
a heat transfer unit which defines a first portion of the working fluid flow duct, wherein the first heat exchanger is in heat transfer communication with the heat transfer unit via a main passage for a first heat transfer medium, and the first heat exchanger is configured such that it is operable to transfer heat to the heat transfer unit from working fluid passing the first heat exchanger; and
a second heat exchanger is located in the working fluid flow duct in flow series between the compressor module rotor and the compressor module outlet in the heat transfer unit, and the second heat exchanger is configured to be operable to transfer heat to the heat transfer unit from the working fluid passing the second heat exchanger.
