Experimental study on the performance of a novel composite phase change energy storage material for clean heating
To achieve green and clean energy heating, improve the performance of phase change material energy storage heating systems (PCMEHS), a novel magnesium chloride hexahydrate/expanded graphite/calcium hydroxide composite phase change material (CPCM) was developed. The thermal properties and phase separation characteristics of the CPCM were experimentally characterized. The results show that MgCl2·6H2O/EG CPCM composed of 7.5% EG has good thermal storage performance without affecting the phase change performance. On this basis, the nucleating agent calcium hydroxide was added to further eliminate the supercooling of the material. The thermophysical properties of the ternary CPCM were tested, and the samples were characterized and analyzed from the microstructure. The thermal conductivity of the ternary CPCM is 2.825 W·m−1·K−1, about 4.66 times that of pure MgCl2·6H2O (0.606 W·m−1·K−1), and the supercooling is 0°C. The results of these thermal characteristics show that MgCl2·6H2O/EG/Ca(OH)2 CPCM has great application potential in clean and green energy heating system.
