风循环系统优化对风冷冰箱能效提升的研究

Study on-improvement of energy efficiency of frost free refrigerator by the way of the optimization of air circulation system

本文以一款对开门风冷冰箱产品作为研究对象,依据初步摸底测试数据结果,分析此款冰箱风循环系统设计中存在的不足,再通过理论分析、CFD分析以及风压-流量测试验证等手段制定出风循环系统的优化设计方案。根据优化方案制作出原理样机并完成整机性能测试。结果表明,经过优化设计的风循环系统可以实现此款对开门冰箱整机耗电量降低约20%的目标要求。

An frost free refrigerator with side-by-side combination doors as the research object in this paper. Shortcomings of the refrigerator air circulation system design are analyzed on the basis of the results of preliminary diagnostic test data. Optimized design schemes of air circulation system are developed through the theoretical analysis, CFD and pressure-flow testing and so on. A prototype is fabricated according to the optimization schemes and the performance test of the frost free refrigerator is completed. The results show that the goal of reducing the energy consumption by about 20% can be achieved by the way of the optimization of the air circulation system for the frost free refrigerator with side-by-side combination doors.
