In latent heat storage, heat is used to induce a phase change in the storage material: solidification, evaporation, condensation, or sublimation. The energy required to produce these phenomena is very high, which make these systems much more compact than the equivalent storage systems based on sensible heat, and since a material ...
They feature mirrors to reflect and concentrate the sunlight, receivers to collect the solar energy and to change it into heat energy and finally, a generator that produces electricity from the heat energy. ...
The influence of key parameters like heat transfer fluid (HTF) inlet temperature, initial temperature of phase change material (PCM) and mass flow rates of HTF on entropy generation number is analysed. ...
By Jason Deign A Spanish team has uncovered a radical new encapsulated phase-change material (PCM) storage system after creating a novel modelling tool for CSP. ...
Energy efficiency in new buildings can be achieved by passive measures such as the insulation of the building envelope, optimised solar design, optimised natural lighting, wall shading, surface material etc. and active measures such as efficient cooling and ventilation appliances and solar water heating. In this paper, the effects of thermal mass and phase ...
The first one is temperature distribution in the phase change material (PCM) during the phase change processes. The second one is the thermal characteristics of the paraffin wax, which includes total melting and total solidification times, the nature of heat transfer phenomena in melted and solidified PCM and the ...
Nowadays for solar heating applications, usage of phase change materials (PCM) to store the heat in the form of latent heat is increased, because large quantity of thermal energy is stored in small volume. ...
The third one is a pilot project using TES in micro-encapsulated phase change materials in a test cabin in Adana with a floor area of 4 m². By using a 3.5 kg Phase Change Material (PCM) together with insulation panels in the test cabin, 7% cooling energy and 28% heating energy can be conserved. ...
Here, the advantages of a trans-heat container using a Phase Change Material (PCM), co-production using an endothermic reaction, and a TED using oxides are theoretically explained from the viewpoint of exergy loss minimisation, respectively.Keywords: exergy loss, industrial waste heat, PCM, phase change ...
The objective of this work is the study of an industrial process of energy storage which consists in the use of a cylindrical tank filled with encapsulated Phase Change Materials (PCM). A particularity is present in this kind of processes; it concerns the delay of the crystallisation of PCM, called supercooling phenomenon. ...
103 J/kg) was used as a latent heat storage material. Experiments were conducted during a winter season to study the latent heat storage units and the thermal performance of the rectangular shaped foot warmer was found better than the cylindrical shaped with the same storage capacity. The experimental thermal performance studies of these latent heat storage systems showed that ...
