Abstract
A refrigerator includes a compressor to compress refrigerant, a condenser to liquefy the refrigerant supplied from the compressor, a capillary tube to decompress and expand the refrigerant supplied from the condenser, an evaporator to vaporize the refrigerant supplied from the capillary tube, a shutoff valve installed at an inlet of the capillary tube so as to prevent the refrigerant in the condenser during stoppage of the compressor from being moved to the evaporator, and a control unit to enable the shutoff valve to be blocked together so as to prevent movement of the refrigerant from the condenser to the evaporator during stoppage of the compressor, and to enable the shutoff valve to be opened together so as to move the refrigerant from the condenser to the evaporator during starting of the compressor.
