摘要： A refrigerant recovery operation method for use in a refrigerator in which a freezing chamber and a refrigerating chamber are independently cooled is disclosed. The refrigerator and the method for controlling the same provide for performing the refrigerant recovery operation not only when the compressor starts operation but also before the compressor stops operation. The refrigerator increases the refrigerant recovery amount within a predetermined pressure range in which the compressor can operate, and controls the refrigerant recovery operation time according to the outdoor air temperature.

摘要： A refrigerant recovery operation method for use in a refrigerator in which a freezing chamber and a refrigerating chamber are independently cooled is disclosed. The refrigerator and the method for controlling the same guarantee a sufficiently long refrigerant recovery operation time by performing the refrigerant recovery operation not only when the compressor starts operation but also before the compressor stops operation, resulting in implementation of the highest operation efficiency of a refrigerating chamber. The refrigerator guarantees high reliability of the compressor by increasing the refrigerant recovery amount within a predetermined pressure range in which the compressor can operate, and maintains an optimum refrigerant amount by variably controlling the refrigerant recovery operation time according to the outdoor air temperature, resulting in improvement of energy efficiency.
摘要翻译： 公开了一种在冷冻室中独立冷却冷冻室和冷藏室的制冷剂回收操作方法。 冰箱及其控制方法通过不仅在压缩机开始运转而且在压缩机停止运转之前进行制冷剂回收运转，能够保证足够长的制冷剂回收运转时间，从而实现制冷室的最高运转效率 。 冰箱通过在压缩机能够运转的规定压力范围内增加制冷剂回收量来保证压缩机的高可靠性，通过根据室外空气温度可变地控制制冷剂回收运转时间来维持最佳制冷剂量，从而提高压缩机的可靠性 的能源效率。
