Paraffin wax (PW) is an energy storage phase change material (PCM) with high energy storage capacity and low cost. However, the feasibility of its application in solar thermal storage has been limited by leakiness during solid-liquid phase conversion, low thermal conductivity, single heat capture mode and low energy conversion rate.
Phase change material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa; thus, PCMs are classified as latent heat storage (LHS) units.
The application of phase change materials has found importance in various systems from energy storage to thermal protection (Krupa et al., 2007). Application of Paraffin Wax in Iraq:-
At the temperature of 323 K, the adsorption heat of the activated carbon can be up to 762.47 kJ/kg, which is much higher than the latent heat of phase change of traditional phase change materials
Thermal energy storage can be classified as sensible heat storage, latent heat storage and chemical heat storage. Latent heat storage with phase change materials (PCMs) is particularly attractive since it provides high storage density and can remain nearly constant temperature during charging and discharging processes [4] .
