Abstract
The present invention relates to a refrigerator and a method for controlling a refrigerator, and more particularly to a refrigerator and a method for controlling a refrigerator in which unnecessary operation of a compressor is prevented for saving power consumption of the refrigerator. The refrigerator includes a compressor, a refrigerating chamber evaporator and a freezing chamber evaporator connected to the compressor, a refrigerant valve for guiding refrigerant to the refrigerating chamber evaporator or the freezing chamber evaporator, and a control unit for controlling the refrigerant valve such that the refrigerant valve blocks or introduces the refrigerant to cause an inside pressure of the freezing chamber evaporator to be elevated higher than an inside pressure of the refrigerating chamber evaporator during evaporation at the refrigerating chamber evaporator for the compressor to draw in the refrigerant remained in the freezing chamber evaporator which did not evaporate.
