摘要

三水醋酸钠（SAT）因相变潜热大、相变温度适宜等优点而可作为太阳能集热领域的储能材料。但SAT在相变过程中存在过冷、相分离等缺陷。利用不同增稠剂和纳米成核剂对其进行改性研究,制备出性能良好的复合SAT。研究发现复合SAT不仅改善了原来的缺点,还具备良好的热性能,且论述了SAT相分离与过冷机理及其解决办法,对增稠剂和成核剂抑制SAT相分离与过冷进行了对比,以及复合SAT改性后在太阳能领域的应用方向。

Abstract

Sodium acetate trihydrate （SAT） has been identified as a potential energy storage material in the field of solar thermal collectors because of its advantageous latent heat of phase transition and suitable phase transition temperature. However, SAT is subject to defects such as subcooling and phase separation during the phase transition. In the present study, a range of thickeners and nano-nucleating agents were utilised in the modification of SAT, with the objective of producing composite SAT with optimal performance. It was observed that the composite SAT not only ameliorated the inherent limitations of SAT, but also exhibited favourable thermal properties. The study proceeded to explore the mechanism of phase separation and subcooling of SAT, and the associated solutions. A comparative analysis was conducted on the inhibition of phase separation and subcooling of SAT with thickening and nucleating agents. Finally, the potential applications of the composite SAT in solar energy post-modification were examined. Following the modification of composite SAT, the subsequent direction of application in the field of solar energy is discussed.
