Abstract


The Latent Heat Storage (LHS) unit is particularly attractive due to its high-energy storage density and its isothermal behavior during the energy storing and retrieval process (phase change process). Among the various types of storage system, the packed bed unit filled with encapsulated Phase Change Material (PCM) balls received the attention of the researchers for various applications in recent years. A good understanding of the heat transfer processes involved in a packed bed latent heat storage system unit is essential, for accurately predicting the thermal performance of the system and for avoiding a costly system over design.
