摘要
相变储能材料具有能量存储密度高、热容大和热稳定性较好等优点,广泛应用于各类储能系统。就低温相变储能材料(温度低于20℃)进行综述,重点介绍了低温相变材料的分类及其载体的研究,并探讨了相变材料在空调、建筑及食品保鲜等领域的研究进展。最后对未来相变材料的发展方向和应用前景进行了展望。
Latent heat storage using phase change materials （PCM） is one of the most efficient methods to store thermal energy, with high energy storage density, heat capacity and thermal stability. In this paper, materials used by researchers as potential PCM at low temperatures （less than 20℃） are summarized and some of their thermophysical properties are reported. The scope of the work was focused on different aspects： classification of PCM, carrier, and the applications of cold thermal energy storage. Prospects for research focus and application of low-temperature phase change materials in the future are also proposed.
