a flow rate sensor configured to sense a flow rate of water from an external water supply source, and to output a sensing signal; and

a controller configured to control the valve assembly in response to the sensing signal, wherein, in response to receiving a water supply request for the first ice maker while water is supplied to the second ice maker, the controller is configured to cut off the supply of water to the second ice maker, to store, based on the sensing signal, an amount of the water that has been supplied to the second ice maker until the controller cuts off the supply of water to the second ice maker, and to supply water to the first ice maker, and wherein, in response to receiving a water supply request for the second ice maker while water is supplied to the first ice maker, the controller is configured to withhold a supply of water to the second ice maker, and to supply, based on the sensing signal, a predetermined amount of water to the first ice maker.

2 . The refrigerator of claim 1 , wherein the plurality of ice makers further comprises a door ice maker disposed at a door of the refrigerator, and wherein in response to receiving a water supply request for the second ice maker while water is supplied to the door ice maker, the controller is configured to control the valve assembly to cut off the supply of water to the door ice maker and to supply water to the second ice maker.

3 . The refrigerator of claim 1 , the plurality of ice makers further comprises a door ice maker disposed at a door of the refrigerator, wherein in response to receiving a water supply request for the first ice maker while water is supplied to the door ice maker, the controller is configured to control the valve assembly to cut off the supply of water to the door ice maker and to supply water to the first ice maker.

4 . The refrigerator of claim 1 , further comprising:

a dispenser disposed at a door of the refrigerator, and configured to discharge water, wherein in response to receiving a water supply request for the dispenser while water is supplied to any one of the plurality of ice makers, the controller is configured to control the valve assembly to cut off the supply of water to the any one of the plurality of ice makers and to supply water to the dispenser.

5 . The refrigerator of claim 1 , comprising a machine room, wherein the flow rate sensor and a compressor are disposed in the machine room.

6 . The refrigerator of claim 1 , comprising:

a filter configured to remove foreign substances in water; and

a water tank configured to store water.

7 . The refrigerator of claim 1 , wherein the valve assembly includes a three-way valve configured to selectively supply water drawn through a pipe to the first ice maker or the second ice maker.

8 . A refrigerator, comprising:

a plurality of ice makers configured to provide ice, the plurality of ice makers includes a first ice maker and a second ice maker;

a plurality of valves configured to control a supply of water to each of the plurality of ice makers;

a flow rate sensor configured to sense a flow rate of water from an external water supply source, and to output a sensing signal; and

a controller configured to control the valves in response to the sensing signal, wherein the first ice maker is disposed in a freezing compartment, and configured to provide spherical ice, and the second ice maker is disposed in the freezing compartment and spaced from the first ice maker, and configured to provide ice by using a tray, wherein the controller is configured to control the valves to cut off the supply of water to the second ice maker, to store, based on the sensing signal, an amount of the water that has been supplied to the second ice maker until the controller cuts off the supply of water to the second ice maker, and to supply the water to the first ice maker, and wherein, in response to receiving a water supply request for the second ice maker while water is supplied to the first ice maker, the controller is configured to withhold a supply of water to the second ice maker, and to supply, based on the sensing signal, a predetermined amount of water to the first ice maker.

9 . The refrigerator of claim 8 , wherein the plurality of ice makers further comprises a door ice maker disposed at a door of the refrigerator, and wherein in response to receiving a water supply request for the second ice maker while water is supplied to the door ice maker, the controller is configured to control the valves to cut off the supply of water to the door ice maker and to supply water to the second ice maker.

10 . The refrigerator of claim 8 , wherein the plurality of ice makers further comprises a door ice maker disposed at a door of the refrigerator, and wherein in response to receiving a water supply request for the first ice maker while water is supplied to the door ice maker, the controller is configured to control the valve assembly to cut off the supply of water to the door ice maker and to supply water to the first ice maker.

11 . The refrigerator of claim 8 , further comprising:

a dispenser disposed at a door of the refrigerator, and configured to discharge water, wherein in response to receiving a water supply request for the dispenser while water is supplied to the second ice maker, the controller is configured to control the valve assembly to cut off the supply of water to the second ice maker and to supply water to the dispenser.
