Method for controlling a refrigerator having a direction control valve

Abstract

A method for controlling a refrigerator having a direction control valve drives a refrigerating fan for a predetermined time when a refrigerant passage is converted to make a refrigerant from a condenser firstly pass a refrigerating evaporator, and enhances a cooling efficiency by applying a residual cool air of the refrigerating evaporator to a refrigerating compartment, after the refrigerating compartment reaches a steady state in a refrigerator having a refrigerating evaporator embodied as an intercooler evaporator. The method includes the steps of: (a) determining whether a refrigerating compartment temperature sensed by a refrigerating compartment temperature sensor reaches a refrigerating compartment set temperature to determine a steady state of a refrigerating compartment; (b) if it is determined that the steady state of the refrigerating compartment in the step (a), switching a direction control valve, and allowing a refrigerant to firstly pass a refrigerating evaporator; (c) if the direction control valve is switched in the step (b), driving a refrigerating fan for a predetermined time simultaneously driving a freezing fan; and (d) if the refrigerating fan is driven for the predetermined time in the step (c), stopping the refrigerating fan.
