风冷冰箱蒸发器非均匀结/除霜特性研究综述OA

Non-uniform frost accumulation on evaporator coils is a significant feature in air-cooled refrigerators.It is also one of the important causative factors leading to evaporator performance degradation.This paper reviews related research in three distinct areas:non-uniform frost characteristics of air-cooled refrigerator evaporators,defrost optimization based on these characteristics,and frost detection optimization.A concise introduction is provided into the formation mechanism of non-uniform frost on air-cooled refrigerator evaporators,the influencing factors,and their impact on refrigerator performance.Frost-heat matching defrosting and frost suppression strategies for the evaporators of air-cooled refrigerators are systematically summarized.The complex challenges and solutions of direct and indirect frost detection techniques under non-uniform frost conditions are analyzed.The performance degradation of air-cooled refrigerator evaporators is summarized and discussed.Finally,this study identifies shortcomings in the research field of non-uniform frost on air-cooled refrigerator evaporators and proposes potential future development directions.This study aims to provide a framework for the efficient operation and energy-saving optimization of air-cooled refrigerators.
