Abstract

Decentralized multi-generation systems using renewable energy sources have great potential for combating climate change and promoting sustainable development. This study models and analyzes an integrated solar-assisted system consisting of an organic Rankine cycle, a wind turbine, and a thermoelectric unit using EES software. Performance is evaluated through exergy, emergoeconomic, and emergoenvironmental analyses. The economic emergy coefficients are steam turbine (59.93%), evaporator (1.66%), working fluid pump 1 (37.25%), warm sea water pump2 (86.86%), cold sea water pump3 (86.97%), solar collector (100%), wind turbine (100%), and thermoelectric unit (100%). Environmental emergy coefficients are steam turbine (58.56%), evaporator (87.15%), working fluid pump 1 (48.97%), warm sea water pump2 (8.39%), cold sea water pump3 (7.68%), solar collector (100%), wind turbine (77.57%), and thermoelectric unit (100%). The system also reduces carbon dioxide emissions by 1.34 tons, highlighting the technical, economic, and environmental benefits of renewable energy integration.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
