摘　　要：依据GB/T 8059-2016《家用和类似用途制冷器具》标准,风冷冰箱耗电量由稳定状态功耗和化霜及恢复期耗电量增量两部分组成,根据标准定义,化霜及恢复期耗电量增量是指无霜电冰箱由于化霜及恢复期产生的额外的电能消耗(本文简称化霜增量)。对于单系统风冷冰箱,其化霜及恢复期耗电量增量占比高达12%以上。通过研究化霜加热器优化设计,化霜及恢复期阶段电动风门开关、变频压缩机转速和风扇电机转速等负载控制策略,达到降低化霜及恢复期耗电量增量,实现降低风冷冰箱耗电量。以某款大容积对开门单系统风冷冰箱BCD-540W为载体,通过降低化霜增量一系列方案实施,冰箱化霜增量降低43.30%,标准耗电量降低6.40%。According to GB/T 8059-2016"Household and similar refrigerating appliances",the power consumption of air-cooled refrigerator is composed of stable state power consumption and the power consumption increment of frost and recovery period.According to the standard definition,the power consumption increment of frost and recovery period refers to the additional power consumption generated by frost-free refrigerator by frost and recovery period(this paper is referred to as frost increment).The frost and recovery period power consumption increment accounted for more than 12%.By studying the optimization design of frost heater,and studying the load control strategies of electric air valve switch,frequency conversion compressor speed and fan motor speed,reduce the power consumption increment of frost and recovery period,and reduce the power consumption of air-cooled refrigerator.With a large volume BCD-540W air-cooled refrigerator as the carrier,through a series of schemes,the frost increment of refrigerator is reduced by 43.30%,and the standard power consumption is reduced by 6.40%.
