Summary

PERFORMANCES OF HEAT EXCHANGERS-ACCUMULATORS WORKING WITH PHASE-CHANGE MATERIALS (PCM) ARE LIMITED BY THEIR DISCHARGE POWER. THE PURPOSE OF THE STUDY IS TO OUTLINE THE INFLUENCE OF CRYSTALLINE KINETICS AND OF SUBCOOLING ON THE RECOVERY POWER OF THESE ACCUMULATORS. THE BEHAVIOUR OF A LAYER OF MATERIAL WITH A PCM REPRESENTATIVEOF SALT HYDRATES, BOTH TAKING INTO ACCOUNT, OR NOT, THE KINETICS OF CRYSTAL GROWTH IS INVESTIGATED. BASED ON THE ENTHALPY METHOD, THE MODEL LEADS TO THE CLASSICAL RESULTS RELATED TO THE SOLIDIFICATION OF A SUBSTANCE HAVING GREAT CHEMICALPURITY, AND DEMONSTRATES THE DIFFERENCE OBSERVED FOR TECHNICAL MATERIALS, OR MIXED PRODUCTS, IN PURELY THERMODYNAMIC CONDITIONS.
