This paper deals with the experimental investigation of transient behavior and thermal storage capability of a sensible heat storage unit. The former is designed to store solar energy by using sand as a storage medium. A cubic unit has been designed employing three configurations of embedded charging tubes to study the performances of the system. The storage material used in this experimentation (sand) has been characterized by its, grain size, density, and heat capacity. Performances of the thermal storage bed (including charging time, energy stored rate, charging energy efficiency) have been evaluated for selecting the storage material. From our experiments, we found that the number of charging tubes affects significantly the storage performances.
Key words: Heat storage / characterization / design / sand / thermal behavior
