The thermodynamic optimum point of the suction air cooling gas turbine cycle with a vapor compression refrigerator is investigated. The maximum thermal efficiency and the maximum specific power increase monotonously with a rise of the temperature ratio by the suction air cooling, but the rate of increase of the thermal efficiency has a tendency to give the optimum value and that of the specific power has a tendency to decrease monotonously, compared with the conventional cycle. The effect of the reversed cycle (refrigerator) on the normal cycle (heat engine) is investigated. The effect on the thermal efficiency is larger than that on the specific power in the region of high temperature ratios.
