Phase Change Material Selection for Thermal Processes Working under Partial Load Operating Conditions in the Temperature Range between 120 and 200 °C

摘要: In some processes, latent heat thermal energy storage (TES) systems might work under partial load operating conditions (the available source is discontinuous or insufficient to completely charge the phase change material (PCM)). Therefore, there a need study how these affect discharge process design control strategy that can benefit user of systems. The aim this paper show and perform at laboratory scale selection PCM, with temperature between 120 200 °C, which will be further used in an experimental facility. Beyond typical PCM properties, sixteen PCMs are studied here from cycling stability point view, as well health hazard view. After 100 melting freezing cycles, seven candidates out present suitable behaviour five them maximum thermal-stable higher than °C. Two final for loads approach found range, named high density polyethylene (HDPE) adipic acid.
