The Suction Air Cooling Gas Turbine with Vapor Compression Refrigerator : The 1st Report, General Characteristic Performance

Abstract

To improve the performance of a gas turbine, the authors investigated the suction air cooling gas turbine cycle with a vapor compression refrigerator, where the refrigerator driven directly with a part of turbine output cools the suction air to reduce the required power of the air compressor. Based on the thermodynamic characteristics of this combination cycle, the authors are fully convinced that it is possible to improve the thermal efficiency and specific power in addition to suppress the variation of the performance due to a change in atmospheric temperature.
