摘要
风冷冰箱的结霜和化霜问题,是影响其发展和制约其节能降耗水平提高的最主要因素。本文以一款单系统风冷冰箱BCD-409W为研究对象,通过仿真分析软件优化冷藏回风道结构来优化蒸发器的结霜均匀性,设计了新的回风道结构,并取得了良好的试验和应用效果。经过实验验证,优化后的风道结构使结霜更加均匀,32℃能耗化霜时间减短了4.5 min,能耗降低了1.66%。总的来说,通过冷藏回风道的结构优化可以提高此款风冷冰箱的蒸发器化霜能力,同时也为其他产品及新品项目提供了相关的解决方案。
The frosting and defrosting of air-cooled refrigerator is the most important factor that affects its development and restricts its improvement of energy saving and consumption reduction.Taking a single system aircooled refrigerator BCD-409W as the research object,this paper optimized the frost uniformity of the evaporator by optimizing the structure of the return air duct through the simulation analysis software,designed a new return air duct structure,and achieved good experimental and application results.After the experimental verification,the optimized air duct structure made the frosting more uniform,the defrosting time of 32℃energy consumption was reduced by 4.5 min,and the energy consumption was reduced by 1.66%.In general,the structure optimization of the return air duct can improve the defrosting ability of the evaporator of this air-cooled refrigerator,and also provide relevant solutions for other products and new product projects.
