本文介绍近年来相变蓄冷技术的研究现状及其进展。指出采用水的相变蓄冷技术已相对成熟,特别是静态冰蓄冷技术已得到普及,动态冰蓄冷技术中的传统的冰浆发生方法也得到了广泛应用,但新型的过冷水动态冰浆发生方法还处在实验室研究阶段;气体水合物蓄冷已有小型系统在实验室内成功运行,但若要投入实际应用,尚需假以时日;潜热型功能热流体蓄冷还处于理论和实验研究阶段。 This article introduces the research status and progress of phase change storage technology in recent years. It is pointed out that the phase-change thermal storage technology using water is relatively mature, especially the static ice storage technology has been popularized. The traditional method of ice-slurry generation in dynamic ice-storage technology has also been widely used. However, Still in the laboratory research stage; gas hydrate storage has been a small system successfully run in the laboratory, but to put into practical application, still take time; latent heat storage fluid is still in theoretical and experimental phase.
