Energy, exergy, economic, and environmental (4E) analyses and optimization of a CCHP system with steam turbine

Due to finding solutions reduce energy consumption and improve the electricity production efficiency in power cycles, using waste heat of cycles combined generation systems can be a useful approach. Also, by wasted cooling heating demands met. Therefore, this study presents energy, exergy, economic, environmental evaluations new configuration cooling, heating, (CCHP) or tri-generation system with steam turbine. This CCHP includes boiler, turbine, exchanger, single-effect absorption chiller, pumps. Some important performance parameters such as electrical efficiency, well exergy are considered. various output percentage operational cost reduction, fuel pollutant emission economic technical issues based on different inlet temperatures pressures turbine investigated. In addition, chiller at operating conditions has been shows that usage leads reduction 24.91% carbon dioxide emission, 15.83% consumption, 35.34% costs compared conventional systems. results show there is good improvement overall 82.46%.
