Due to the necessity of achieving the energy systems with improved efficiency, combined power plants are developing in recent decades. Moreover, employing renewable energy sources in the power generation and heating/cooling purposes is an attractive idea to obtain more environmentally benign energy systems. In the current study, a combined cooling and power (CCP) plant is analyzed based on exergy and economic concepts. Afterward, by adding lithium‐bromide refrigeration cycle and parabolic solar collectors, the plant is investigated. The exergy efficiency, carbon dioxide emission, and cost of generated electricity are evaluated on the basis of SPECO model. The results of the study show that thermal and exergy efficiencies of the CCP plant with the solar collector depend on various parameters and can be affected significantly. The efficiency of the plant after applying lithium‐bromide refrigeration cycle and the solar collector increased from 50.33 to 51.73%, while the exergy efficiency enhanced from 47.48 to 48.22%. In addition, it was concluded that adding the collector and absorption chiller leads to 1.5% reduction in environmental pollutants.
La République islamique fut fondée en 1979 sur une théologie politique maximaliste basée sur le velayat e faqih ou « loi du jurisconsulte ». Plus de trente ans plus tard, cette idéologie a dégénéré en un culte de la personnalité qui exclut non seulement les forces séculières mais également tous les fidèles de l’islam qui ne sont pas loyaux à l’actuel jurisconsulte au pouvoir. Que le Guide suprême parvienne à supprimer l’opposition ou que l’opposition le défasse, le futur du clergé en Iran demeure ambigu.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
