Abstract: A refrigerator and a method for controlling the same are disclosed. A refrigerator includes a timer for measuring an interval of one hour after power is supplied to the refrigerator, a door opening/closing sensor for sensing opening and closing of a door, a storage unit for storing information whether door is opened in a sector defined as one hour by the timer and at least 7 sector units each having 24 consecutive sectors, and a control unit for predicting a refrigerator use pattern in 24 sectors by overlapping 7 sector units, performing a normal operation mode to maintain a storage compartment at a first desired temperature in a sector in which door opening is predicted, and performing a power-saving operation mode to maintain the storage compartment at a second desired temperature higher than the first desired temperature in a sector in which door opening is not predicted.
