PURPOSE: A refrigerator is provided to save vacuum time by encouraging the degasifying of inert gas dissolved in oil in vacuum suction in the production process of a refrigerator. CONSTITUTION: A refrigerator comprises a freezing cycle(20), a process pipe(34) and a vacuum pipe(80). The freezing cycle comprises a compressor(21), a condenser(22), an expansion valve(23) and an evaporator. The compressor, the condenser, the expansion valve, and the evaporator are successively connected to a refrigerant pipe(25). Oil and inert gas flow into through the process pipe. The vacuum pump is connected to one side of the refrigerant pipe and discharge air in the refrigerant pipe. When the freezing cycle is mounted on the refrigerator, the inert gas dissolved by the oil is degasified by the pumping of the oil due to the rotation of a rotating shaft(60) in a process of operating the vacuum pump for the vacuum discharge of the freezing cycle. |
