Résumé

A cool thermal storage process, largely used for air conditioning and refrigeration process, consisting in the use of the solid-liquid transformation of Phase Change Materials (PCM) encapsulated in spherical nodules, is investigated. Theses nodules fill a tank placed in the refrigeration loop.
An experimental study of a tank with a reduced size, filled with randomly dispersed commercial nodules in the charge mode, is presented.
A simplified model, taking into account the undercooling and the erratic character of the crystallization of the PCM, confirms the experimental results for various flow rates and inlet temperatures of the chilling fluid and permits the detailed analysis of the energy storage.
