Evaluation of the state of charge of a solid/liquid phase change material in a thermal energy storage tank
Zsembinszki, Gabriel; Orozco, Christian; Gasia, Jaume; Barz, Tilman; Emhofer, Johann; Cabeza, Luisa F. (MDPI, 2020)Monitoring of the state of charge of the thermal energy storage component in solar thermal systems for space heating and/or cooling in residential buildings is a key element from the overall system control strategy point ... -
Phenomenological modelling of phase transitions with hysteresis in solid/liquid PCM
Barz, Tilman; Emhofer, Johann; Marx, Klemens; Zsembinszki, Gabriel; Cabeza, Luisa F. (Taylor & Francis, 2019)Technical-grade and mixed solid/liquid phase change materials (PCM) typically melt and solidify over a temperature range, sometimes exhibiting thermal hysteresis. Three phenomenological phase transition models are presented ... -
Techno-economic analysis of a heat pump cycle including a three-media refrigerant/phase change material/water heat exchanger in the hot superheated section for effi cient domestic hot water generation
Emhofer, Johann; Marx, Klemens; Barz, Tilman; Hochwallner, Felix; Cabeza, Luisa F.; Zsembinszki, Gabriel; Strehlow, Andreas; Nitsch, Birgo; Wiesflecker, Michael; Pink, Werner (MDPI, 2020)Integration of a three-media refrigerant/phase change material (PCM)/water heat exchanger (RPW-HEX) in the hot superheated section of a heat pump (HP) system is a promising approach to save energy for domestic hot water ...
