Abstract: The present invention relates to a valve control method for a refrigerator, and more particularly, to a valve control method for a refrigerator which controls a three-way valve for opening and closing refrigerant channels to a refrigerating chamber evaporator and a freshening chamber evaporator. The present invention is provided with the three-way valve of an AC valve for controlling the refrigerant to flow into the refrigerating chamber and the freshening chamber evaporator. In addition, in order to reduce driving noise generated from the three-way valve, the three-way valve is controlled to operate at a point of time when a predetermined time has passed after the compressor is driven. As a result, since driving noise caused from the three-way valve is drowned out by the driving noise of the three-way valve, an advantage of reducing the noise of the three-way valve can be expected.
