摘　　要：本文建立了一新型蓄冰板释冷过程数学模型,模拟分析了释冷过程中板内中心点温度、含冰量、蓄冰板释冷量及其内部参数的变化情况。研究表明,蓄冰板释冷过程中,中心点温度和含冰量变化均分为三个阶段,且第二阶段的融冰过程随着载冷剂流速的增加而缩短。蓄冰板单位时间内释冷量随载冷剂流速增加而增加,但低载冷剂流速下冰板释冷量更稳定。In this paper,a new mathematical model of ice storage plate is established,and the changes of temperature,ice content,cooling capacity and internal parameters of ice storage plate are simulated and analyzed.The results show that the temperature and ice content at the center of the ice storage plate can be divided into three stages,and the ice melting process in the second stage shortens with the increase of the refrigerant flow rate.The cooling capacity per unit time of ice storage plate increases with the increase of refrigerant flow rate,but the cooling capacity of ice storage plate is more stable at low refrigerant flow rate.
