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.
