卧式双温无霜冰柜的研发及应用

Development and application of horizontal double temperature frostless freezer

本文提出并详细分析了三种卧式双温无霜风冷冰柜方案的优缺点,针对其中之一的结构设计进行详细研究,利用CFD仿真优化风道效率,提升箱体性能,最终制作产品样机试验验证。结果显示,样机满足新国标一级能效和T型高环温储藏温度,去除内置辅助风道显著降低了产品安装工艺难度,风冷无霜、冷藏室变温以及间室精确控温极大的提升了消费者体验,为卧式冰柜无霜化、风冷化提供一些参考。

In this paper,the advantages and disadvantages of the three horizontal double temperature frostless air-cooled freezer are analyzed in detail.The structure design of one of them is studied.CFD simulation is used to optimize the efficiency of the air duct,improve the performance of the box,and finally make a prototype test.The results show that the sample machine meets the first level energy efficiency and the T type performance test.The removal of the built-in auxiliary air duct significantly reduced the difficulty of the product installation process.The air-cooling frost free,the temperature change and the precise temperature control greatly improved the consumer experience,and provided some reference for the horizontal air-cooling freezer.
