Evaluación de una Instalación de Refrigeración por Absorción con Energía Solar
Monné Bailo, Carlos (Universidad de Zaragoza) ; Alonso, Sergio ; Palacín, Fernando
Resumen: Se ha evaluado el comportamiento de una instalación de refrigeración solar por absorción, acoplada con un sistema de disipación geotérmica. La metodología de estudio se ha basado en el análisis de los valores registrados con sondas de temperatura, caudal y radiación, durante el período 2007-2009. Los registros indican que el coeficiente de funcionamiento varió entre 0.47 y 0.56 y la potencia de refrigeración producida entre 3.5 y 5.8 kW. Estos resultados se han comparado con los de la misma instalación pero que disipa calor por medio de una torre de refrigeración seca (aerotermo). Se ha comprobado que la instalación de refrigeración se comporta de un modo más estable utilizando el sistema de disipación geotérmico. Sin embargo, para bajas temperaturas, el uso del aerotermo es más eficiente.
The performance of a solar cooling absorption installation, coupled with a geothermal heat rejection system has been evaluated. The methodology was based on the analysis of the values recorded by temperature, flow and radiation probes, during the period 2007-2009. The data obtained show that the coefficient of performance varied between 0.47 and 0.56 and the cooling capacity produced varied between 3.5 and 5.8 kW. These results have been compared with those of the same installation but in which heat was dissipated using a dry cooling tower. The study demonstrated that the cooling system behaves in a more stable manner using the geothermal heat rejection system. However, for low temperatures, the use of the dry cooling tower is more efficient.
