Resumen
Elpresente trabajo se realizó en el Hospital Provincial Clínico Quirúrgico Universitario “Arnaldo Milián Castro” de Santa Clara, con el objetivo de seleccionar una alternativa de suministro energético basado en un sistema de cogeneración o trigeneración para dicho hospital, a partir del estudio de las demandas de portadores energéticos en el 2010. Para ello se realizó una revisión bibliográfica acerca de los aspectos fundamentales de la cogeneración y la trigeneración. La caracterización de las demandas efectuada para el propio año mostró que la energía eléctrica fue el portador más consumido con 1 410,8 tcc, seguido del combustible fuel oil con 294,7 tcc, el GLP con 14,4 tcc y el diesel planta con 2,8 tcc. El propio estudio permitió construir las curvas de la simultaneidad de las demandas de
electricidad, calor y frío, las cuales conjuntamente con los índices de trigeneración calculados sirvieron de base para la selección de las alternativas de trigeneración propuestas, de las cuales resultóla variante de turbina A3a3 lade mejores resultados, pues permite cubrir completamente lasdemandasde electricidad, calor y frío, con ahorros de 936 tcc/año y de 161 MUSD/año, ademáspresentó los mejores resultados del VAN y la TIR, estos fueron de 1,6 millones de dólares y del 56%,respectivamente, con un PRI de dos años aproximadamente. El análisis medioambiental arrojóque esta alternativa es la de menor impacto ambiental, ya que las reducciones globales de emisionescontaminantes son de 3767 toneladas de CO2, 0,3 toneladas de CO, 15 toneladas de NOx y 174 toneladas de SO2 anualmente.
This work was performed at the Hospital Provincial Clínico Quirúrgico Universitario “Arnaldo Milián Castro”inSanta Clara, in order to select an energy alternative based on cogeneration or trigeneration system of thishospital, from the study of the energydemands of 2010. This literature review was performed on the fundamental aspects of cogeneration and trigeneration. The characterization of the demands made for thisyear showed that electricity was the mostconsumed with a total of 1410,8tcc, followed by fuel oil with294,7tcc,14,4tcc of GLPand for the diesel plant 2,8tcc.This studyalsomade it possible to construct curves of the simultaneous demands for electricity, heat and air conditioning, along with trigeneration indices were calculated which was thebasis for the selection of the proposed trigeneration alternatives, which resulted in the alternativeof turbine A3a3, which givedthe best results, andcan completely satisfythe demands for electricity, heat and air conditioning, with savings of 936 tcc/yearand 161 million USD / year, it alsopresented the best results of the VAN and TIR, these were 1,6 million and 56%, respectively, with a PRI of about two years. The environmental analysisfound that this alternative is the least environmentally deadly, as the global emissions reductions are 3 767 tons of CO2, 0,3 tons of CO, 15 tons of NOx and 174 tons of SO2 annually.
