Phase change material or PCM is a material that can absorb, store and release large amounts of latent heat within a specific temperature range during phase transition reaction. Several materials have been identified as a latent heat storage medium and are classified as organic PCMs, eutectics, inorganic PCMs and clathrate hydrate. Paraffin is an alkane organic PCM, effective for latent heat storage medium via their melting transition and is recently studied in different applications such as solar thermal storage, air-conditioning buildings, integration with fabrics intended for special environmental conditions and others. In this application, sample observation DSC was performed to evaluate the thermal behavior of paraffin wax.
