WebPlace some solid paraffin wax into a large test tube. Heat the test tube in a water bath until the temperature of the paraffin wax is about 80 °C. Remove the test tube from the water bath and place it in the iced water. Start recording the temperature of the paraffin as it falls until the temperature has fallen to about 30 °C. WebThe innovative latent TES system investigated was designed to achieve short characteristic times of thermal charge and discharge. For this purpose, a 3-dimensional metal structure was fabricated via laser powder bed fusion (L-PBF) and then infiltrated by paraffin wax.

Its latent heat of fusion is 2.2x105 J/kg, its latent heat of vaporization is 1.6x106 J/kg, its specific heat … WebGenerally, paraffin wax is employed in TESUs as a phase change material (PCM) . There are some advantages of paraffin, which are the absence of phase separation and constant latent heat of fusion [10,11]. One of the main characteristics of paraffin wax is its low melting point, which allows its usage in low-temperature systems .
