Abstract
A thermodynamic apparatus (10) comprising a compressor module (100), a turbine module (200), and a regenerative heat exchanger (300) centred on a central axis (12). The compressor module (100), turbine module (200) and regenerative heat exchanger (300) are arranged in series along the central axis (12) such that the regenerative heat exchanger (300) is provided between the compressor module (100) and the turbine module (200).
Claims20
A thermodynamic apparatus comprising:
- a compressor module;
- a turbine module;
- and
- a regenerative heat exchanger centred 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.
1 more element
A thermodynamic apparatus comprising:
- a compressor module comprising a first heat exchanger, and a first rotor;
- a turbine module comprising a second heat exchanger, and a second rotor;
- a regenerative heat exchanger arranged in series along a central axis such that the regenerative heat exchanger is provided between the compressor module and the turbine module;
- and
- a shaft rotatable about the central axis and extending through each of the compressor module, turbine module, and regenerative heat exchanger, both the first and second rotors being carried on and rotatable with the shaft;
- wherein the compressor module, turbine module, and regenerative heat exchanger define a working fluid flow duct which extends, in series, through each of (a) a compressor module inlet to a compressor module outlet, (b) a first path through the regenerative heat exchanger, (c) a turbine module inlet to a turbine module outlet, and (d) a second path through the regenerative heat exchanger, which is in heat transfer communication with the first path.
