间冷式冰箱箱体模型研究

Researches on Cabinet Model of Indirect Cool Refrigerator

间冷式电冰箱箱体结构中存在流动换热的结构，这一特点决定了该类电冰箱箱体模型的建立与求解有别于直冷式．通过结构分析，提出简化边界条件的处理方法，并采用ｚ传递系数求解空气循环冷却系统的动态换热．模型的计算结果与针对性的实验结果吻合较好，为间冷式电冰箱的系统动态仿真奠定了基础．

The establishment and solution of cabinet models of indirect cool refrigerator are different from that of direct cool refrigerator. By analysis of cabinet structure, this paper presents the method of simplifying boundary condition and uses z transfer function to solve dynamic heat transfer of air circulation cool system. The calculation well agree with the experiment. It lays the foundation for the system dynamic simulation of indirect cool refrigerator.
