Abstract:
1. A machine unit layout system, comprising: a drive unit; a low-pressure-side compressor unit and a high-pressure-side compressor unit in a single-shaft multistage structure, the compressor units each including a plurality of sections, the compressor units being disposed in an interrupted arrangement on both sides of the drive unit, the pluralities of sections in the low-pressure-side compressor unit and the high-pressure-side compressor unit being arranged so as to have two gas flow directions which are opposed directions along rotor shafts; and a low-pressure-side expander unit and a high-pressure-side expander unit in a single-shaft multistage structure, the expander units each including a plurality of sections, the expander units being disposed in an interrupted arrangement outside the compressor units, the pluralities of sections in the low-pressure-side expander unit and the high-pressure-side expander unit being arranged so as to have two gas flow directions which are opposed directions along the rotor shafts, each of the units being coupled to one another by rotor shafts composed of a single shaft to optimize distribution of torque in each rotor shaft.
