Claim 8:
9. The thermodynamic apparatus of claim 8, wherein:
a third sub-passage extends through the third heat exchanger, and the third heat exchanger is in flow series between a first inlet to the third sub-passage and a first outlet from the third sub-passage, the first inlet configured to receive heat transfer medium from the inlet plenum of the compressor module, the first outlet being configured to exhaust into the outlet plenum of the compressor module;
a fourth sub-passage extends through the fourth heat exchanger, and the fourth heat exchanger is in flow series between a second inlet to the fourth sub-passage and a second outlet from the fourth sub-passage, the second inlet configured to receive heat transfer medium from the inlet plenum of the turbine module, the second outlet being configured to exhaust into the outlet plenum of the turbine module;
the first heat exchanger is provided in series along the first sub-passage between an inlet to the first sub-passage and the third heat exchanger, and the third heat exchanger is provided in flow series between the first heat exchanger and an outlet from the first sub-passage; and
the second heat exchanger is provided in series along the second sub-passage between an inlet to the second sub-passage and the fourth heat exchanger, and the fourth heat exchanger is provided in flow series between the second heat exchanger and an outlet from the second sub-passage.
