The authors analyze the performance at the partial load of the suction air cooling gas turbine cycle with a vapor compression refrigerator. The partial load is adjusted by changing the inlet gas temperature of the turbine, keeping the number of revolutions of the turbine and the flow rate of the inlet air of the air compressor in a constant state. The analytic results show that the gains in thermal efficiency and specific power at the partial load are in the same degree as at the design point, and that this cycle can suppress a variation of the performance caused by a change in atmospheric temperature at the partial load as well as at the design point, compared with conventional cycle.
