Numerical simulation and experimental research progress of phase change hysteresis: A review

Phase change materials in thermally activated building systems: A comprehensive review

“…For extended discussions of supercooling and phase change hysteresis issues, the reader is referred to. [62][63][64]…”

“…Drawbacks of supercooling could be higher energy consumption and removal of only sensible loads 62 . Another issue is phase change hysteresis, which can be interpreted as a delay between the enthalpy‐temperature curves of the solidification and melting processes 63,64 . Such issues are challenging to account for in most of the state‐of‐art models of PCMs, especially those adopted for building applications (discussed in Section 3.5).…”

“…A recent extended discussion of this topic can be found in Reference 67. For extended discussions of supercooling and phase change hysteresis issues, the reader is referred to 62–64 …”

“…For such reasons, PCMs have been gaining increasingly attention during the last few decades. Que et al [28] recently discussed the issues specifically related to phase change hysteresis and supercooling phenomena during the phase transition of the PCM. In [29], an updated review on the performance, applications, and key challenges of inorganic PCM in the building sector is presented.…”
