Abstract

By employing the energetic optimization technique, the optimal performance of a focusing collector-driven, irreversible Carnot refrigerator with three heat sources and a combined heat engine is investigated A minimum operating parameter and a relation between the maximum overall efficiencies are obtained for the systems under consideration, A minimum value for the total solar insolation needed to overcome internal irreversibilities for start-up of the systems is defined and the effect of the collector design parameters on this value is investigated.
