Phase change material selection for thermal processes working under partial load operating conditions in the temperature range between 120 and 200 ÂșC
In some processes, latent heat thermal energy storage (TES) systems might work under partial load operating conditions (the available thermal energy source is discontinuous or insufficient to completely charge the phase change material (PCM)). Therefore, there is a need to study how these conditions affect the discharge process to design a control strategy that can benefit the user of these systems. The aim of this paper is to show and perform at laboratory scale the selection of a PCM, with a phase change temperature between 120 and 200 ÂșC, which will be further used in an experimental facility. Beyond the typical PCM properties, sixteen PCMs are studied here from the cycling and thermal stability point of view, as well as from the health hazard point of view. After 100 melting and freezing cycles, seven candidates out of the sixteen present a suitable cycling stability behaviour and five of them show a maximum thermal-stable temperature higher than 200 ÂșC. Two final candidates for the partial loads approach are found in this temperature range, named high density polyethylene (HDPE) and adipic acid.The work was partially funded by the Spanish government (ENE2015-64117-C5-1-R

Els treballs han estat realitzats manera individual per part dels estudiants dels grups M-3 i T-1 de lâassignatura BotĂ nica FarmacĂšutica durant els mesos de febrer a maig del curs 2014-15 com a resultat final del Projecte dâInnovaciĂł Docent «Jardins per a la salut: aprenentatge servei a BotĂ nica farmacĂšutica» (codi 2014PID-UB/054). Tots els treballs sâhan dut a terme a travĂ©s de la plataforma de GoogleDocs i han estat tutoritzats pels professors de lâassignatura. Lâobjectiu principal de lâactivitat ha estat fomentar lâaprenentatge autĂČnom i col·laboratiu en BotĂ nica farmacĂšutica. TambĂ© sâha pretĂšs motivar els estudiants a travĂ©s del retorn de part del seu esforç a la societat a travĂ©s dâuna experiĂšncia dâAprenentatge-Servei, deixant disponible finalment el treball dels estudiants per a poder ser consultable a travĂ©s dâuna Web pĂșblica amb la possibilitat de poder-ho fer in-situ en el propi jardĂ mitjançant codis QR amb un smartphone
