Modelo de equilibrio químico para representar solubilidades de sistemas ternarios y su aplicación a la predicción de eutécticos de sistemas cuaternarios
Lovera, Jorge A.; Ushak, Svetlana; Flores, Elsa K.; Fernández, Ángel G.; Galleguillos, Hector (Universidad de Tarapacá, 2020)Incorporar la energía solar en el sector habitacional requiere de materiales adecuados para el almacenamiento de energía. Algunas mezclas eutécticas de sales inorgánicas hidratadas son una buena alternativa. Habitualmente ... -
Solar water heating system and photovoltaic floating cover to reduce evaporation: Experimental results and modeling
Taboada, M.E.; Cáceres, L.; Graber, T. A.; Galleguillos, Hector; Cabeza, Luisa F.; Rojas, R. (Elsevier, 2017)The arid conditions in northern Chile restrict the access to water and energy. This work describes the experimental behavior of a solar water heating system combined with floating covers and photovoltaic cells. Two similar ... -
Thermophysical characterization of a by-product from the non-metallic industry as inorganic PCM
Ushak, Svetlana; Gutiérrez, Andrea; Galleguillos, Hector; Fernández, Ángel G.; Cabeza, Luisa F.; Grágeda, Mario (Elsevier, 2015)Physical characterization and thermal properties of bischofite, a by-product from the non-metallic industry, were determined and compared with those to MgCl2 6H2O with the idea of using it as phase change material in ... -
Use of polyethylene glycol for the improvement of the cycling stability of bischofite as thermal energy storage material
Gutiérrez, Andrea; Ushak, Svetlana; Galleguillos, Hector; Fernández, Ángel G.; Cabeza, Luisa F.; Grágeda, Mario (Elsevier, 2015)Bischofite is a by-product of the non-metallic mining industry. It has been evaluated as phase change material in thermal energy storage, but it shows little cycling stability, therefore in this paper the mixture of ...
