Claim 4:
5. The thermodynamic apparatus of claim 4, wherein the portion of the working fluid flow duct is a first portion of the working fluid flow duct, and the turbine module defines a second portion of the working fluid flow duct which extends between the turbine module inlet and the turbine module outlet configured to expand a working fluid as the working fluid passes along the working fluid flow duct, wherein:
the second heat transfer unit defines the second portion of the working fluid flow duct in flow series between the turbine module rotor and the turbine module outlet; and
the second heat exchanger is configured such that it is operable to transfer heat received from the second heat transfer unit to working fluid passing the second heat exchanger.
