Optimum power boosting of gas turbine cycles with compressor inlet air refrigeration

A conceptual gas turbine cycle with refrigerated air supplied to the compressor inlet is proposed to increase the cycle specific net power significantly and render it practically insensitive to seasonal temperature fluctuations. it is optimized for maximum power per m(3)/s and maximum power per kg/s of induced air. These cycle performances are evaluated in a numerical example for two refrigeration cycle efficiencies, based on state-of-the-art isentropic efficiency coefficients of the compressor and turbine. The specific hears of air and products of combustion are treated as temperature-dependent parameters to be determined as integrated mean averages.
