This present paper is focused on the study of high temperature thermal energy storage
(TES) using phase change materials (PCM) to be applied on cooling and refrigeration systems
by solar cooling. Thus, a pilot plant with a working temperature range between 150
and 200 C was designed and built at the University of Lleida (Spain). Hydroquinone was
selected for the specific application from different PCM candidates as the most suitable
material after a literature review and a differential scanning calorimetry (DSC) analysis.
This PCM has a phase change temperature range between 166 C and 173 C and a melting
enthalpy of 225 kJ kg 1. Two storage configurations were evaluated using the same PCM to
have preliminary results before the final storage tank design. From the pilot plant results
and experience, a 5 Tn PCM storage tank was designed and built to work in a real solar
cooling installation in Seville (Spain).
