Summary

While unloading a latent heat storage, the solid-liquid interface moves away from the heat transfer surface and the heat flux decreases due to the increasing thermal resistance of the growing layer of the molten-solidified medium. This effect can be reduced using techniques to increase heat transfer. In this paper, three methods of heat transfer enhancement in a cold storage working with water-ice as PCM are compared including a new PCM-graphite composite material. This material showed an increase in heat flux bigger than with any of the other techniques.
