Web29 dec. 2024 · Otherwise, there would be loss of water via evaporation which would critically affect the performance of the salt hydrate PCM. Kinetic Properties Supercooling —Solidification of PCM below the melting temperature (range generally 10–20 °C) due to poor nucleating properties and inadequate rate of crystallization is known as supercooling. WebThe proposed salt hydrate PCM was synthesized at various concentrations of related components and after detecting the optimum compound, it was tested under several cycles to ensure its sustainable heat storage capability.

Webspace around the PCM material drops, the Phase Change Material solidifies, releasing its stored latent heat. PCMs absorb and emit heat while maintaining a nearly constant temperature. Within the human comfort and electronic-equipment tolerance range of 20°C to 35°C, latent thermal storage materials are very effective. The most commonly used PCMs are salt hydrates, fatty acids and esters, and various paraffins (such as octadecane). Recently also ionic liquids were investigated as novel PCMs. As most of the organic solutions are water-free, they can be exposed to air, but all salt based PCM solutions must be encapsulated to prevent water evaporation or uptake. Both types offer certain advantages and disadvantages and if they are correctly applied some of the disadvanta…
