Abstract
ABSTRACTThe main purpose of this paper is to improve optimal design and analysis of Combined Cooling, Heating and Power production (CCHP) system for an office building of Qom University based on hybridization of solar energy and gas turbine cycle. The proposed system is an integration of a gas turbine, a solar plate collector, a heat recovery steam generator, a steam turbine, and absorption chiller. To calculate solar energy dynamically, the transient simulation has been considered. In this regard, thermodynamic modeling and dynamic simulation of hybrid Solar-CCHP have been performed in TRNSYS software. Furthermore, energetic, exergetic, economic, exergoeconomic, and exergoenvironmental modeling and analysis have been performed in different modes dynamically. So, the computer code has been developed to perform these analyses. In addition, multi-objective optimization through NSGA-II with maximum exergy efficiency, minimal total exergy cost and minimal exergoenvironmental impacts have been performed simultaneously. The results show that the three objective parameters have been improved in cooling mode compared to base system at 3%, 15%, and 10%, respectively, and in heating mode at 11%, 12%, and 32%, respectively.
