Thermophysical heat storage for cooling, heating, and power generation
Thermophysical heat storage is a general term to effectively combine sensible heat and latent heat storage. In particular, both sensible heat and latent heat appear when using PCM for TES, as shown in Fig. 1. The sensible heat and latent heat are derived from the temperature change and phase change, respectively.
