| contents | Techno feasibility analysis of a concentrating solar thermal cooling systems at a university complex Lucas de Oliveira Alves Diego Cunha Malagueta Elisa Pinto da Rocha Ingeniería simulation absorption refrigeration Concentrating solar energy Concentrating solar thermal (CST) energy applications are growing worldwide, especially in combined cooling, heat, and power processes. Building upon the analysis of a building’s thermal comfort, and software simulations for CST, the current study evaluates a solar conditioning system integrated with absorption systems. The cooling system is equipped with single-, double- and triple-effect configurations cycle, production parameters, and thermal storage. The required fraction of auxiliary energy for the system operation is estimated. The results indicate that the double effect system is the best configuration for the adopted location in Brazil. The system’s annual auxiliary energy demand is, approximately, 20%. Triple-effect systems require less energy at higher temperatures due to local direct radiation, which then leads to an intermittent operation and greater auxiliary energy demands. The methodology applied in this work could be adopted in different locations, with an emphasis on the possibility of testing smaller scale systems in small buildings. 2021 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49671281032 https://www.redalyc.org/journal/496/49671281032/ https://www.redalyc.org/journal/496/49671281032/html/ https://www.redalyc.org/journal/496/49671281032/49671281032.epub https://www.redalyc.org/journal/496/49671281032/movil 10.15446/dyna.v88n217.93033 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.217 Vol.88 |
