Résumé

The present paper is focused on the study of the high temperature thermal energy storage (TES) using phase change materials (PCM) to be applied on cooling and refrigeration systems by solar cooling. For that purpose, a pilot plant with working temperature range between 150 – 200°C was built at the University of Lleida (Spain). Hydroquinone was selected from different PCM candidates as the most suitable material after a differential scanning calorimetry (DSC) analysis and a literature review for the specific application due to its characteristics: having a phase change temperature range between 166°C and 173°C and a melting enthalpy of 205.8 kJ/kg. Two similar storage tanks based on the shell-and-tubes heat exchanger design were built in order to perform thermal cycles of charging and discharging processes. Moreover from the pilot plant results and experience, another tank following the same design and using the same PCM was built and placed on the roof of the Engineering School of Sevilla building for solar cooling applications.
