Abstract: A refrigerator may include: a storage chamber, a first ice-maker, a second ice-maker, a cooler for supplying the cold to the storage chamber and the ice-making chamber, an ice bin for storing ice generated by the second ice-maker, a water supply unit for supplying water to the ice-making cell, a heater for supplying heat to the ice-making cell, and a controller for controlling the heater. The controller may increase the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is increased, and decreases the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is reduced.
