Abstract: A method for controlling a refrigerator according to an embodiment of the present invention comprises the steps of: determining whether or not an ultra-low temperature compartment mode is turned on; determining whether or not an ultra-low temperature compartment load-responsive operation input condition is satisfied; and determining whether or not a freezer compartment load-responsive operation input condition is satisfied, wherein if the ultra-low temperature compartment mode is turned on, and the ultra-low temperature compartment load-responsive operation input condition and the freezer compartment load-responsive operation input condition are both satisfied, a corresponding ultra-low temperature compartment load-responsive operation is preferentially performed.

Abstract: A method for controlling a refrigerator, according to an embodiment of the present invention, comprises: a step in which it is determined whether a period of defrosting (POD) for defrosting a freezing compartment and a deep-freezing compartment has elapsed; a step in which, when it is determined that the period of defrosting has elapsed, a deep cooling operation for cooling at least one from among the temperature of the deep-freezing compartment and the temperature of the freezing compartment to be lower than a control temperature is performed; and a step in which, when the deep cooling operation finishes, a defrosting operation for defrosting the freezing compartment and the deep-freezing compartment is performed. When the defrosting operation starts, a freezing compartment valve is closed so as to prevent cold air from flowing to a freezing compartment evaporator and a heat sink, and at least a portion of a freezing compartment defrosting section and at least a portion of a deep-freezing compartment defrosting section overlap with each other.
