摘要
根据无霜冰箱蒸发器的化霜原理,针对现有的冷冻蒸发器化霜系统存在的问题,提出了改进方案。利用冷藏室循环热进行化霜预处理,通过改进前后的实验并进行对比分析,可以得出以下结论:在不增加任何成本的基础上,提高了化霜系统的可靠性并且降低了27%的化霜能耗。
An improvement control program design is proposed that the cycling heat of refrigerating chamber is used for pre-treatment before electrical heating defrost system begin to work.It is found that the reliability of the defrost system improved and the defrost energy is saved by 27%.
