摘要
无机水合盐相变储能材料(PCMs)具有化学性质稳定、工作温度恒定、相变温度适中、相变潜热及导热系数大、潜热值高、成本低等优点,在实际的生产生活中具有广阔的使用前景和发展空间。然而,过冷、相分离、导热系数问题、循环稳定性差等问题限制了此材料的实际应用。主要介绍了无机水合盐相变储能材料最新的研究进展和成果、分类以及解决过冷度和相分离等问题的改性方法,最后,指出了目前水合盐相变储能材料存在的不足并对未来的重点研究方向做出了展望。
Inorganic hydrated salt phase change energy storage materials(PCMs)have the advantages of stable chemical properties,constant working temperature,moderate phase change temperature,large phase change latent heat and thermal conductivity,high latent heat value,and low cost,which have broad application prospects and development space in actual production and life.However,many problems,such as supercooling,phase separation,thermal conductivity,poor cycle stability,etc.,limit the practical application of this material.This article mainly introduced the latest research progress and achievements of inorganic hydrated salt phase change energy storage materials,as well as the classification and modification methods to solve the problems of subcooling and phase separation.Finally,it pointed out the shortcomings of hydrated salt phase change energy storage materials and the key research directions in the future.
