利用冷藏室循环热进行化霜预处理的蒸发器化霜系统的试验研究

摘要

An improved control program design was proposed that the cycling heat of refrigerating chamber was used for pre-treatment before electrical heating defrost system began to work. It is found that the reliability of the defrost system improved and the defrost energy was saved by 27%.%　　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，通过改进前后的试验对比分析，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
