Can phase change materials be used as latent heat thermal energy storage?

Possible combinations of active and passive heating applications of PCM proposed by this study. 6. Conclusion and recommendations A review on recent research literature in regarding to the usage of phase change materials as latent heat thermal energy storage strategies applied to residential and commercial buildings is presented in this article.

Can phase change materials reduce energy demand in building sector?

An extensive technique, regarding cooling and heating improvement by reducing the energy demand in building sector, is the application of phase change materials known as “PCM”. PCM has received much attention and has become a topic with a lot of interest among architects and engineers in the last four decades .

Do PCMS store more heat energy during phase change?

Similarily, PCMs with high latent heat can store more heat energy during phase change, enhancing their heat transfer efficiency (Abu-Hamdeh and Alnefaie, 2019). In addition, denser materials can store more heat energy per unit volume (Radomska, 2021).

Do thermal batteries need phase change materials & sensible heat storage materials?

Also, utilising phase change materials (PCMs) and sensible heat storage materials is critical for operating thermal batteries as they provide the necessary thermal energy storage (Jouhara et al., 2020, Naghavi et al., 2021).

Which factors affect the efficiency of heat transfer in PCMs?

The efficiency of heat transfer in PCMs is affected by thermal conductivity, specific heat, phase change temperature and latent heat, density, melting temperature, supercooling, thermal stability, dependable freezing behaviour, and cycling stability (Abu-Hamdeh and Alnefaie, 2019, Eletskii, 2022, Radomska, 2021).

How does a PCM store thermal energy?

During phase transition from solid to liquid, PCMs store thermal energy in the form of latent heat by an endothermal process that dissolves the PCM's chemical bonds, and release it exothermally when being cooled to recover its solid state [55, 81, 82]. PCM then is said to act as a thermal storage .
