Abstract

This paper, illustrates a design and simulation of a solar powered absorption refrigeration system preserves food above freezing point. Th main system is modifid from a commercial conventional system located at Tajoura, Libya. Th target is to design and operate the system at high solar fraction and effiency.
The simulation is performed by TRNSYS to evaluate the annual thermal performance of the solar system that consists of 50-kW absorption chiller producing cold for three refrigerated rooms. The model could be classifid into two main parts; refrigeration load model and solar powered refrigeration system model. The results demonstrated that the optimum system achieves 51% solar fraction consists of 48 m2 of high performance evacuated tubes solar collectors and 5000-litre thermal storage tank, in order to power a 50-kW absorption chiller that offrs cold for three refrigerated rooms of vegetables
