摘要： An embodiment according to the present invention is to provide a control method of a refrigerator that can operate a compressor before a start of a defrost operation and during a predetermined time to supply a high-temperature hot gas to an evaporator. With the control method of the refrigerator according to the embodiments of the refrigerator, the compressor is driven immediately before the defrost operation and the blower fan cooling the compressor stops, such that the high-temperature hot gas can be supplied to the evaporator, thereby increasing the defrost efficiency.

摘要： A refrigerator is provided. The refrigerator includes a compressor, a condenser, an expansion valve, an evaporator, a bypass pipe, and a valve device. The condenser condenses refrigerant discharged from the compressor, and the expansion valve expands the refrigerant condensed in the condenser. The evaporator evaporates the refrigerant expanded in the expansion valve, and the bypass pipe allows the refrigerant discharged from the compressor to move toward an inlet of the evaporator. The valve device allows the refrigerant discharged from the compressor to selectively move toward the bypass pipe or the condenser. The valve device comprises an inlet, a first outlet, and a second outlet. The refrigerant discharged from the compressor flows into the inlet. The refrigerant is discharged toward the condenser through the first outlet, and is discharged toward the bypass pipe through the second outlet. The first outlet has a diameter larger than that of the second outlet.

摘要翻译： 提供冰箱。 冰箱包括压缩机，冷凝器，膨胀阀，蒸发器，旁通管和阀装置。 冷凝器冷凝从压缩机排出的制冷剂，并且膨胀阀膨胀在冷凝器中冷凝的制冷剂。 蒸发器蒸发在膨胀阀中膨胀的制冷剂，并且旁通管允许从压缩机排出的制冷剂朝向蒸发器的入口移动。 阀装置允许从压缩机排出的制冷剂选择性地朝着旁通管或冷凝器移动。 阀装置包括入口，第一出口和第二出口。 从压缩机排出的制冷剂流入入口。 制冷剂通过第一出口朝向冷凝器排出，并通过第二出口向旁通管排出。 第一出口的直径大于第二出口的直径。
