摘　　要：冰浆具有良好的流动性、载热性能和传热性能,现在已广泛应用于间接制冷系统中。本文主要介绍了计算冰浆热物性的数学模型,简述了计算冰浆热物性的程序。利用程序计算了添加剂为乙醇的冰浆的基本热物性数据,通过与单相乙醇水溶液热物性对比,分析了冰浆热物性所具有的优点,并对冰浆热物性模型研究的不足和以后重点研究方向进行了分析。最后指出了在研究冰浆热物性过程中应该注意的一些关键问题。Ice slurry has widely been used in various indirect refrigeration systems recently, due to its good liquidity, heat-carry characteristics and heat transfer characteristics. In this paper, mathematical models of its thermal properties are reviewed generally, then the calculation procedure of its thermal properties is introduced briefly. Basic thermal properties data of ice slurry which use ethyl alcohol as its additive have been calculated according to the procedure, and then are compared with that of ethyl alcohol. Next, the advantages of ice slurry thermal properties are analyzed according to the comparison, then the disadvantage of the research and research prospects in future are introduced. Finally, some key issues about the thermal properties of ice slurry are presented.
