Abstract: A refrigerator may include a body having a freezing chamber and a refrigeration chamber, a cooling circuit for cooling the freezing chamber and the refrigeration chamber, and a power source for supplying power to the cooling circuit. The refrigerator may further include a thermosyphon provided between the freezing chamber and refrigerating chamber. A control circuit may be connected to the thermosyphon to control a flow of refrigerant in the thermosyphon. The control circuit may include a valve provided on a circulation path of the thermosyphon, a electrical power storage device connected between the power source and the valve, and a switching circuit provided between the valve and the electrical power storage device. When the power source does not supply power to the cooling circuit, the control circuit may operate the thermosyphon using power stored in the electrical power storage device.

Abstract: A refrigerating cycle apparatus is provided. The refrigerating cycle apparatus may include a refrigerant switching valve, which may be moved to a predetermined position through a simple circuit structure, during a blackout (power outage). Further, in a case in which input power is cut off due to a blackout, while the refrigerating cycle apparatus operates, oil may be collected. Even if input power is cut off due to a power outage, in a state in which the refrigerant switching valve is open while a refrigerating cycle apparatus having two compressors of two stages (2tage-2comp) is operating, the refrigerant switching valve may be converted to a closed state. This may reduce a pressure difference between the two compressors, and prevent damage to the compressors.

Abstract: A refrigerator equipped with a door that becomes transparent as necessary to make the interior thereof visible is disclosed. The refrigerator includes a cabinet having a storage compartment defined therein, a lighting device for illuminating the interior of the storage compartment, a door, which is hingedly coupled to the cabinet to open and close the storage compartment, and has an opening and a panel assembly including a front panel disposed on the front surface thereof, a sensor for detecting sound waves, which are generated by a knock input applied to the door and are transmitted through the front panel, and a controller for controlling the lighting device to allow light to be transmitted through the panel assembly, thus making the storage compartment visible from outside the door through the opening when a predetermined knock input is detected.
