Abstract: In this work, the design models of the gas turbine (GT), as well as the thermodynamic models in which the turbine operates, were passed in order to be able to calculate the rates of thermal energy and energy leaving the system and the thermal efficiency of the system in various climatic conditions. Variable atmospheric air (temperature and specific humidity of the air entering the turbine) we chose the evaporative cooling system (VCS) because the climatic conditions of desert regions with high temperature lack moisture, which requires a significant reduction in temperature to reach the required humidity ratio meaning greater cooling loads this problem was solved by sprinklers. It works to moisten the inlet air at the expense of reasonable cooling loads. The results showed that when the temperature of the air entering the turbine is reduced to (10?), the percentage of useful work of the turbine will increase to (18%) and the thermal efficiency of the system will increase to about (4%). From these data it can be said the development of the gas turbine with the initial cooling of the air entering the turbine gives the best performance of the system compared to the old systems.
