Evaluation of thermo-physical properties and thermal energystorage performance of phase change material systems

Phase change materials (PCMs) are organic or inorganic compounds that, based on their latent heat of fusion, canabsorb and store large amounts of thermal energy during the phase change transition. The key challenges ofdetermining the specific heat capacity (𝐶𝑝) and thermal diffusivity (α) in order to check the preservation of thespecified temperature range, have been identified. In this study, the design was carried out in isothermal and nonisothermalconditions. By calculating and determining the values of thermal diffusivity and specific heat capacityusing the Time-Temperature History test design, it was shown that the shape stabilized PCM system has the functionof maintaining temperature in the temperature range of ۳۷–۴۲ °С.
