We also identify future research opportunities for PCM in thermal energy storage. Solid-liquid phase change materials (PCMs) have been studied for decades, with application to thermal management and energy storage due to the large latent heat with a relatively low temperature or volume change.
To achieve a high heat storage density at small volume change, most applied PCM undergo a phase change between solid and liquid; the phase change is then called melting and solidification. Some PCM however undergo a phase change between two different solid phases. Thus, in general, PCM refer to a phase change on heating and on cooling.
A parabolic concentrated thermal energy storage unit contains PCM as a storage medium to store the heat effectively. Senthil and Cheralathan (2019) investigated the development of the heat-retaining ability of a solar receiver using sugar alcohol PCMs in a parabolic dish concentrated solar receiver.
Castell (2015) illustrates that, from the primary model to a model developed on the renewable energy transition process, storage of energy can be easily possible. This storage of energy can be easily achieved at a higher rate by PCMs.
Also, reviewed several possibilities to enhance the heat exchange characteristics of PCMs. Salunkhe and Shembekar (2012) carried a review analysis in PCM encapsulation and its significance in enhancing the thermal performance of energy storage medium.
Building materials are part of the building structure, and integrated PCM increases the heat storage ability. If the temperature in the building rises above the phase change temperature, heat is taken up by the PCM in the building material, thereby cooling the building interior until the PCM is totally melted.

Paracetamol, kurz PCM, ist ein antipyretisch und analgetisch wirksamer Arzneistoff aus der Gruppe der Nichtopioid-Analgetika. Es wirkt unter Laborbedingungen auch geringfügig antiphlogistisch. Geschichte. Die Erstsynthese erfolgte 1878 durch den amerikanischen Chemiker Harmon Northrop Morse. Die analgetische Wirkung der Substanz …
