THEORETICAL ANALYSIS OF AIR CONDITIONING BY EVAPORATIVE COOLING INFLUENCE ON GAS TURBINE CYCLES PERFORMANCE

This paper studies the influence of evaporative cooling air conditioning for a gas turbine. A mathematical model of semi-empiric nature for both the evaporative panel and the gas turbine cycle was developed and implemented for computational simulation. The model used for the evaporative panel is based on mass and energy balances as well as in available empirical correlations for commercial evaporative panels. The modeling of the gas turbine cycle is based in non-dimensional numbers obtained from performance maps reproducing actual performance of the compressor and turbine. Simulation results are shown for a wole Test Reference Year in Brasilia allowing to quantify the advantages of evaporative cooling in power output increasing and NOx emission reduction.
