Introduction of the PCM Flux concept for latent heat storage

Kurzfassung

The focus in the development of storage systems using phase change materials is on the implementation of heat transfer concepts compensating the limited heat conductivity of the storage materials. This paper introduces the PCM Flux concept as a new alternative for latent heat energy storage. Here, the storage material is separated mechanically by an intermediate fluid layer from the heat transfer surfaces. This approach avoids the formation of a growing layer of solidified storage material covering the heat transfer structure, which limits the heat flux. This paper outlines the PCM Flux concept and gives results of its theoretical analysis.
