Exergetic and Exergoeconomic Optimization of Gas Turbine Inlet Air Cooling Systems with Absorption or Compression Chilling

The present paper aims to study the effect of cooling air inlet methods on gas turbine compressors increasing their efficiency. After modeling cycles with absorption and compression systems in EES software, these cycles' performance is investigated for all equipment cycle from thermodynamic, exergy, exergoeconomic aspects. In system, conventional solution lithium bromide-water used as a two-component fluid, cycle, R134a operating fluid used. According results, rise system's temperature, total output work decreases. Based analysis, exergy destruction cost dominates initial cost, resulting factor's decline. Relationship predicted by Group Method Data Handling (GMDH) reduce computation time optimization. studied are then subjected two-objective optimization Particle Swarm algorithm using MATLAB software. objective functions related efficiency rate. results reveal contradictory behavior two so that increase efficiency, rate increases.
