Claim 15:
16. A refrigerator comprising:
a storage chamber;
a first ice maker that includes a first tray and a second tray to define a cell that forms a space in which liquid is to phase-change into ice;
a second ice maker disposed in an ice making compartment that is partitioned from the storage chamber;
a cooler configured to supply cold into the storage chamber and the ice making compartment;
an ice bin configured to store ice provided by the second ice maker;
a heater configured to supply; and
a controller configured to:
change the heating amount of the heater based on a change of a heat transfer amount between the cold within the storage chamber and the liquid of the cell so as to maintain an ice making rate of the liquid within the cell within a predetermined range that is less than an ice making rate when an ice making process is performed while the heater is turned off.
