Resumen

The article presents an analysis of technical and economic feasibility of using two configurations of solar cooling in a Cuban hotel. HVAC hybrid schemes are: a cooler of ice water vapor compression (chiller) interconnected in parallel with a smaller capacity chiller, first with a solar-powered absorption cooling system (SACS), and then with a photovoltaic cooling system(PSC). Both were simulated taking into account the weather conditions in the region, thermodynamic calculation methodologies and principles that govern these
technologies. The results show that the use of these alternatives contributes to reducing energy consumption and the environmental impact of heating, ventilation and air conditioning systems (HVAC). Economic analysis
highlights that PCS is more favorable than the SACS taking into account the cooling cost generation (CCG) but energy assessment indicates that SACS has higher thermal performance for the case study to which it is
applied.

El artículo presenta un análisis de factibilidad técnica y económica de uso de dos configuraciones de climatización solar en un hotel cubano. Los esquemas de climatización híbridas son: una enfriadora de agua helada de compresión de vapor (chiller) interconectada en paralelo con una enfriadora de absorción asistida con energía solar térmica (SACS, siglas en inglés), y posteriormente con un chiller asistido por un sistema solar fotovoltaico (PSC, siglas en ingles). Ambos fueron simulados teniendo en cuenta las condiciones meteorológicas de la región, metodologías de cálculo y principios termodinámicos que gobiernan estos
sistemas. Los resultados muestran que el uso de estas alternativas contribuye a la reducción del consumo energético y el impacto ambiental de los sistemas calefacción, ventilación y aire acondicionado (HVAC, siglas en inglés). El análisis económico resalta que PCS es más favorable que el SACS, teniendo en cuenta el costo de generación de frío (CCG, siglas en inglés) pero la evaluación energética indica que este último posee mayores prestaciones térmicas para el caso de estudio al cual se le aplica.
