摘要/Abstract

摘要： 依据大型直冷式制冰机制冰单元的传热形式以及内部相态的改变,将制冰过程划分为水的对流换热降温过程、水的导热换热降温过程、水的冻结过程、冰的降温过程4个阶段。运用能量守恒方程和传热方程等,建立制冰全过程各单元的数学模型,通过MATLAB软件编程求解各阶段的时间。对大型直冷式制冰机制冰单元内的结冰过程进行了试验测定,经验证,传热模型各阶段的计算误差均在8.00%以内,总误差小于4.00%,模型准确性较高。对大型直冷式制冰机的设计优化提供技术指导和理论支持。

Abstract: This study divided the ice making process into four stages based on the heat transfer form of the ice-making unit of the large direct-cooled ice maker and the change of internal phase state: the convective heat transfer cooling process of water, the conductive heat transfer cooling process of water, the freezing process of water, and the cooling process of ice. By using energy conservation equations and heat transfer equations, mathematical models of each unit in the whole ice-making process were established, and the time of each stage was solved by MATLAB software programming. In this study, the icing process in the ice making unit of a large direct-cooled ice maker was experimentally determined. It had been verified that the calculation errors of each stage of the heat transfer model were all within 8.00%, and the total error was less than 4.00%, which indicated the high accuracy of the model. This study provided technical guidance and theoretical support for the design optimization of a large direct-cooled ice maker.
