摘　　要：无霜冰箱采用除霜系统进行自动除霜,除霜方式通常是电加热除霜,根据温度控制器(或温度传感器)确定化霜退出点。根据节能、气候适应性、系统可靠性等方面的设计需要,越来越多的风冷冰箱设计为智能控制结构,采用直流风扇电机进行风路循环。为对无霜冰箱的可靠性进行相对全面的探析,本文从制冷系统、控制系统、排水系统、试验方法等角度对无霜冰箱的可靠性设计进行分析。The frost-free refrigerator with automatic defrost system usually use electric heating for defrosting.According to the temperature controller(or temperature sensor) to determine exit points of frost.According to energy,climate adaptation,system reliability,the design needs,a growing number of air-cooled refrigerators are designed with intelligent control structure,using the DC fan motor to conduc t cycle wind.In order to comprehensively probe the reliability of frost-free refrigerator,this article analyzes from the factors such as refrigeration systems,control systems,drainage systems and test methods.
