Abstract: A refrigerator includes a refrigerating compartment temperature sensor, a cooling apparatus, in a state when driving time points of a refrigerating compartment and a freezing compartment are synchronized, to maintain an inside temperature of the refrigerating compartment by performing a cooling operation of the refrigerating compartment on the basis of a cut-off temperature of the refrigerating compartment that is varied by a difference between a temperature of the refrigerating compartment at a driving time point of the refrigerating compartment that is sensed by the refrigerating compartment temperature sensor and a cut-in temperature of the refrigerating compartment, and a control unit to control the driving of the cooling apparatus by varying the cut-off temperature of the cooling apparatus according to the difference between the temperature of the refrigerating compartment at the driving time point of the refrigerating compartment and the cut-in temperature of the refrigerating compartment.

Abstract: A control method of a refrigerator including a compressor to supply refrigerant to an evaporator to cool a storage compartment, a valve to adjust flow of the refrigerant, a fan to blow air heat-exchanged by the evaporator, and a heater to remove frost from the evaporator. The control method includes, upon receiving a power-saving signal, determining whether the received power-saving signal is a first or second power-saving mode signal, upon determining that the power-saving signal is the first power-saving mode signal, performing at least one selected from among resetting of target temperature of the storage compartment, adjustment of an operation rate of the compressor, and adjustment of operation time of the heater to execute a first power-saving mode, and, upon determining that the power-saving signal is the second power-saving mode signal, controlling the compressor, the fan, and the heater to be off to execute a second power-saving mode.

Abstract: A refrigerator which allows a user to easily open a door of the refrigerator with a small force is disclosed. The refrigerator includes a main body having an upper storage compartment and a lower storage compartment defined on upper and lower sides, a door which slides to open and close any one of the storage compartments, a handle which is disposed at an upper portion of the door to be vertically rotatable, a plurality of push members which move to advanced positions from retreated positions in connection with a vertical rotation of the handle to separate the door from the main body, and an elastic member which is disposed between at least one of the push members and the door to restore the push members to the retreated positions when an external force is removed from the handle.
