摘要
为保证制冷系统高效运行,风冷冰箱需要定期进行除霜。除霜过程包括对蒸发器加热、除霜、处理化霜水等主要步骤,在这个过程中,加热元件产生的热量融化霜层,但同时也带来箱内温度波动和能耗增加等副作用。本文针对化霜加热过程进行分析,探讨更高效的加热控制方法。
To ensure refrigeration system run efficiently,the refrigerator cooled by forced air circulation need defrosting on a regular basis.The defrosting process should include several main steps such as heating the evaporator,melting the frost and disposal the defrosted water.In this process,the heater not only prevent the permanent formation of frost,but also bring some side effects such as temperature fluctuations in the compartment and increase of energy consumption.This paper is dedicated to analyze the process of defrosting to explore more efficient method for controlling the heater.
