中文摘要：

在提出分离式螺旋热管蓄冷空调系统的基础上，建立了螺旋热管蒸发段蓄冰过程的理论模型，分析了单位时间内管外结冰厚度、管外冰层厚度、蓄冰率、单位时间蓄冷量以及系统总蓄冷量随时间的变化关系，并对三种不同管径的螺旋热管的蓄冰特性进行了分析研究，研究结果表明在螺旋热管曲率半径相同的条件下，增大管径可以提高系统的单位时间蓄冷量。

英文摘要：

According to the cool storage air conditioning system with separated helical heat pipe, the physical and mathematic heat transfer model of the ice storage at evaporator section of separated helical heat pipe was built. The thickness of ice layer per unit time,the total thickness of ice layer outside the heat pipe,ice packing factor,cool storage capacity per unit time and the total cool storage capacity of the system during the charging process were achieved. The characteristics of ice storage systems with three different kinds of coil diameters were analyzed. The results indicate that the cool storage capacity per unit time of the system can be increased when the coil diameter increases at the same curvature radius of belical pipe.
