Latent Heat Energy Storage

Latent heat storage systems use the reversible enthalpy change Δh pc of a material (the phase change material = PCM) that undergoes a phase change to store or release energy. Fundamental to latent heat storage is the high energy density near the phase change temperature t pc of the storage material. This makes PCM systems an attractive solution for
