Abstract
The final goal of this study is to implement and to test a thermal energy storage (TES) system using different phase
change materials (PCM) for solar cooling and refrigeration applications. A high temperature pilot plant able to test
different types of TES systems and materials was designed and built at the University of Lleida (Spain). This pilot
plant is composed mainly by three parts: heating system, cooling system, and different storage tanks. The pilot plant
uses synthetic thermal oil as heat transfer fluid (HTF) and has a working temperature range from 100 ºC to 400 ºC.
Two different PCM were selected after a deep study of the requirements of a real solar cooling plant and the available
materials in the market, finally d-mannitol with phase change temperature of 167 ºC and hydroquinone which has a
melting temperature of 172.2 ºC were used.
