Because of its high latent heat and phase change at constant temperature, LHTES offers a high thermal energy storage density with lower temperature variations [16, 17]. Liu et al. [18] investigated the effect of variable temperature of PCMs during the phase transition process on building thermal comfort.
Phase change materials (PCMs) in solar still:
A phase change material (PCM) is a substance with a high heat of fusion that, by melting and solidifying at a particular temperature, may store and release enormous amounts of energy. Because heat is either retained or released as a substance changes from solid to liquid, PCMs fall under the category of latent heat storage (LHS) units.
Three-dimensional rGO@sponge framework/paraffin wax composite shape-stabilized phase change materials for solar-thermal energy conversion and storage
Simultaneously, phase change materials (PCMs) as crucial solar-thermal energy storage medium have become indispensable materials of energy saving system. Nowadays, developing composite PCMs with solar-thermal conversion properties is receiving more and more attention owing to their combination of large energy storage …
Study of the performance of paraffin wax as a phase change material in packed bed thermal energy storage …
The results showed that the faster storage of thermal energy can be made by high flow rate of heat transfer fluid HTF and high inlet temperature of heat transfer fluid. It was found that at 65°C HTF inlet temperature, the melting and solidification processes accelerated by 27.9% and 57.14% respectively, when the flow rate was …
