Abstract :Second law analysis techniques, based on the calculation of entropy generation, are applied to the design and operation of an industrial refrigeration phase-change storage. The studied process consists in the use of encapsulated phase-change materials (PCM). A detailed analysis of the system permitted the development of a simulation program. So, the calculation of entropy generation has been made in a numerical way. The results are only presented for the discharge mode corresponding to the melting of the PCM. This paper was presented at the ECOS’98 Conference in Nancy, June 8-10, 1998Keywords : energy storage, refrigeration, entropy generation, phase change
