结论与展望
近年来，中低温热化学储能技术因其储热密度大、热损失小、可行性高而受到研究人员的关注。水合盐基热化学材料的开发和反应机理的研究也取得了一定的进展。本系列工作主要包括热化学材料的开发和性能调控、储能材料反应机理的揭示及理论模型的构建、储热模块热-质-流-化多场耦合传输机制的探究、以及吸附式热化学储热在建筑节能和器件热管理方面的应用探索。
后续研究中，还可从微观层面，尤其是通过分子动力学模拟的方法，进一步揭示和探讨相关机理。对于储热单元，应结合拓扑优化等方法设计出有利于热质传递、且易扩展和制造的储能反应器并进行数值和实验对比研究。最后，可进一步拓展至热化学储能循环系统，对整个系统的性能，如热效率、㶲效率、经济性等方面进行全面分析。
