摘　　要：本文针对并联双循环风冷冰箱在冷藏室制冷时的制冷剂迁移问题提出了改进方案。通过减小冷冻蒸发器内容积和调整控制的策略,缩短制冷剂迁移的时间,降低冷藏蒸发器过热,达到降低耗电量的目的。采用以上方案的试验样机耗电量降低4.6%。In this paper, an improved scheme is put forward for the refrigerant migration of parallel cycle frost-free refrigerator when the fresh food compartment works. By reducing the volume of the freezer evaporator and adjusting control logic of the refrigerator, the time of the refrigerant migration is shortened, the overheat of the outlet of evaporator is reduced, and the purpose of reducing the power consumption is achieved. The test prototype of the above scheme is used to reduce the power consumption by 4.6 %
