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.
