Applying detailed energy and exergy analyses, as well as an evaluation of environmental impact through Total Equivalent Warming Impact (TEWI), it was identified that the ejector-based configuration as the most energy-efficient, exhibiting a 13.2% reduction in annual power consumption compared to the conventional system. The cascade configuration demonstrated the lowest exergy destruction above 26°C, highlighting its potential under higher ambient temperatures. Furthermore, the ejector-based configuration consistently achieved the highest 2nd law efficiency across the temperature range set. The environmental impact analysis showed the ejector-based configuration also had the lowest TEWI, with a 14.36% reduction. The results underscore the importance of selecting appropriate refrigeration configurations based on local climate conditions. 2024 artículo científico 1657-4583 https://www.redalyc.org/articulo.oa?id=553781720009 https://www.redalyc.org/journal/5537/553781720009/ https://www.redalyc.org/journal/5537/553781720009/html/ https://www.redalyc.org/journal/5537/553781720009/553781720009.epub https://www.redalyc.org/journal/5537/553781720009/movil 10.18273/revuin.v23n3-2024009 en http://www.redalyc.org/revista.oa?id=5537 Revista UIS Ingenierías application/pdf Universidad Industrial de Santander Revista UIS Ingenierías (Colombia) Num.3 Vol.23 |
