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 ]]>
