摘要: 相变蓄冷浆体材料具有良好的流动性和高蓄冷密度,既可用作蓄冷材料,也可作为载冷剂来输送冷量,应用前景广阔。相变蓄冷浆体材料包含冰浆、笼型水合物浆体、微胶囊乳液、相变乳状液和微乳液等,其中笼型水合物又包含CO2水合物、有机制冷剂水合物和季盐类水合物。本文综述了上述相变蓄冷浆体材料的基础物性、制备方法和流动传热特性,并介绍了水合物浆体生成的强化以及浆体流动特性的改善研究,分析比较了几种相变蓄冷材料的优缺点,列举了浆体材料在蓄冷空调系统中的典型应用,并指出了蓄冷技术未来的发展趋势,如尿素–水,乙醇–水和乙二醇–水等自然工质良好的热学性能均为其制备相变蓄冷材料提供了可能。

Abstract: Phase change cold storage slurry material has good fluidity and large cold storage density. It can be used as cold storage material and secondary refrigerant to transport cooling capacity as well, so it has a broad application prospect.Phase change cold storage slurry material includes ice slurry, clathrate hydrate slurry, microcapsule emulsion, phase change emulsion and microemulsion. In addition, the clathrate hydrate comprises CO2 hydrate, organic refrigerant hydrate and quaternary salt hydrate. This article reviews the basic physical properties, preparation methods, flow and heat transfer characteristics of the above phase change cold storage slurry materials, analyzes the advantages and disadvantages of several phase change storage materials and lists several typical applications of slurry materials in cold storage air conditioning systems. At the same time, the research trend of phase change cold storage slurry materials is pointed out. The good thermal properties of natural refrigerants such as urea water, ethanol water and ethylene glycol water provide the possibility for the preparation of phase change cold storage materials.

Key words: cold storage, slurry, phase change materials, preparation methods, flow and heat transfer characteristics
