A super absorbent polymer (SAP) was also used as a thickener to prevent segregation of CaCl₂·6H₂O during phase transition. The combined method of thermogravimetric analysis/differential thermal analysis (TGA-DTA) was firstly proposed to evaluate the segregation of inorganic PCM innovatively. The results showed that using 0.5 wt% flake graphite not only eliminated the supercooling of CaCl₂·6H₂O, but also improved its thermal conductivity for better thermal performance. The results of Fourier-transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM) demonstrated that the flake graphite did play an important role on the crystallization of CaCl₂·6H₂O. Numerical simulation demonstrated that using modified CaCl₂·6H₂O within walls of buildings in Hong Kong and Changsha are economically feasible with the payback periods of 18.3 years and 8.4 years respectively.]]> Mon 29 Jan 2024 17:51:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37860 Mon 29 Jan 2024 17:48:15 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47660 2, readily attaining surface temperatures of 520–530 °C, well above the phase change temperature of 420 °C. Single step charging led to a state of charge of 80% without exceeding a nominal surface temperature of 530 °C. Cycling on and off sun in the range 460–520 °C was used to achieve a state of 99% charged. Thermal performance of the MGA during solar charging and its discharge by natural cooling is presented and analysed.]]> Mon 29 Jan 2024 17:43:40 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48507 4C₃ which would diminish the amount of Al available to act as a PCM. This work presents the effects of extended thermal cycling over the intended use range to test its effect on integrity, phase composition and microstructure of the two candidate materials. A small initial mass loss from the 5 g samples due to the loss of metal particles directly in contact with the surface was observed and which had stabilised after 50–100 cycles. The mass loss is accompanied by a small thermal capacity loss in DTA which also stabilised in the first 50–100 cycles. Both the mass loss and capacity reduction are expected to be greatly reduced in full scale storage modules due to the much smaller surface area to volume ratio (∼0.1) compared with that for the samples used here (∼4). The absence of X-ray diffraction peaks from the carbide Al₄C₃ in data from the cycled materials and their continued strong latent heat DTA signal strongly suggest that the materials are suitable for long-term use in thermal energy storage applications.]]> Mon 20 Mar 2023 16:11:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34244 Fri 21 May 2021 11:16:25 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41733 Fri 12 Aug 2022 13:20:32 AEST ]]>
