In the related art refrigerator, its structure for supplying water to a dispenser and water tank was complicated. In addition, since an icemaker is installed in a refrigerating chamber of the refrigerator, there is a problem in that the water supplied into the icemaker is frozen. Furthermore, if the icemaker is installed in the freezing chamber of the refrigerator in which the refrigerating chamber is formed at a lower portion thereof and a refrigerating chamber is formed at an upper portion thereof, there is another problem in that it is difficult to control the temperature in the refrigerating chamber or ice-making capability of the icemaker is lowered. The present invention is directed to a refrigerator. According to an aspect of the present invention for solving the above problems, there is provided a refrigerator including a refrigerating chamber formed at a relatively upper portion of a refrigerator body and a freezing chamber formed at a relatively lower portion of the refrigerator body, which comprises an ice-making chamber which is partitioned in the refrigerating chamber by means of insulating walls and includes an icemaker for making ice and an ice storage for storing the ice made in the icemaker, a first heat exchanger for generating cold air to regulate the temperature in the ice-making chamber, and a second heat exchanger for generating cold air to regulate the temperature in the freezing and refrigerating chambers, wherein the first and second heat exchanger are components of a heat exchange cycle. According to the refrigerator of the present invention so configured, there are advantages in that the temperature in the refrigerating chamber can be accurately controlled, the loss of cold air can be minimized and the structures for supplying water into the icemaker and the dispenser can be simplified.

The invention claimed is: 1. A refrigerator comprising: a refrigerating compartment; a freezing compartment; an ice compartment located within the refrigerating compartment; an ice maker located within the ice compartment and configured to freeze liquid water into ice; a refrigerator door configure
The invention claimed is: 1. A refrigerator comprising: a refrigerating compartment; a freezing compartment; an ice compartment located within the refrigerating compartment; an ice maker located within the ice compartment and configured to freeze liquid water into ice; a refrigerator door configured to open to enable frontal access and close to inhibit frontal access to at least a portion of the refrigerating compartment; a dispenser, at least a portion of which being located on the refrigerator door, configured to dispense liquid water and frozen water as ice; an ice maker branch line configured to guide liquid water to an inlet of the ice maker located within the ice compartment; a dispenser branch line configured to guide liquid water to the dispenser; and a water supply line that branches into the ice maker branch line and the dispenser branch line, wherein: a branch point, at which the water supply line branches to interface with the ice maker branch line and the dispenser branch line, is located proximate to a wall of the refrigerating compartment; and both the ice maker branch line and the dispenser branch line extend along at least one wall of the refrigerating compartment without extending along a wall of the freezing compartment. 2. The refrigerator of claim 1 wherein: the branch point at which the water supply line branches into the ice maker branch line and the dispenser branch line is located proximate to an uppermost wall of the refrigerating compartment; and both the ice maker branch line and the dispenser branch line extend along the uppermost wall of the refrigerating compartment without extending along a wall of the freezing compartment. 3. The refrigerator of claim 1 further comprising: a water filter configured to, prior to the branch point at which the water supply line branches into the ice maker branch line and the dispenser branch line, filter liquid water guided by the water supply line. 4. The refrigerator of claim 1 wherein the dispenser branch line extends from an uppermost wall of the refrigerating compartment, passes through an upper hinge of the refrigerator door, and extends to the dispenser. 5. The refrigerator of claim 1 further comprising: a first valve configured to regulate flow of water through the water supply line prior to the branch point; a second valve configured to regulate flow of water through the ice maker branch line independently of the first valve; and a third valve configured to regulate flow of water through the dispenser branch line independently of the first valve and the second valve. 6. A method of guiding liquid water in a refrigerator, the method comprising: guiding liquid water along an ice maker branch line configured to guide liquid water to an inlet of an ice maker that is located within an ice compartment and that is configured to freeze liquid water into ice, the ice compartment being located within a refrigerating compartment; guiding liquid water along a dispenser branch line configured to guide liquid water to a dispenser, at least a portion of which being located on a refrigerator door, configured to dispense liquid water and frozen water as ice, the refrigerator door being configured to open to enable frontal access and close to inhibit frontal access to at least a portion of the refrigerating compartment; and guiding liquid water along a water supply line that branches into the ice maker branch line and the dispenser branch line, wherein a branch point, at which the water supply line branches to interface with the ice maker branch line and the dispenser branch line, is located proximate to a wall of the refrigerating compartment, and both the ice maker branch line and the dispenser branch line extend along at least one wall of the refrigerating compartment without extending along a wall of a freezing compartment. 7. The method of claim 6 wherein: the branch point at which the water supply line branches into the ice maker branch line and the dispenser branch line is located proximate to an uppermost wall of the refrigerating compartment; and both the ice maker branch line and the dispenser branch line extend along the uppermost wall of the refrigerating compartment without extending along a wall of the freezing compartment. 8. The method of claim 6 further comprising: filtering liquid water guided by the water supply line prior to the branch point at which the water supply line branches into the ice maker branch line and the dispenser branch line. 9. The method of claim 6 wherein guiding liquid water along the dispenser branch line comprises guiding liquid water along a dispenser branch line that extends from an uppermost wall of the refrigerating compartment, passes through an upper hinge of the refrigerator door, and extends to the dispenser. 10. The method of claim 6 further comprising: regulating, using a first valve, flow of water through the water supply line prior to the branch point; regulating, using a second valve, flow of water through the ice maker branch line independently of the first valve; and regulating, using a third valve, flow of water through the dispenser branch line independently of the first valve and the second valve. 11. A refrigerator comprising: means for guiding liquid water to an inlet of an ice maker that is located within an ice compartment and that is configured to freeze liquid water into ice, the ice compartment being located within a refrigerating compartment; means for guiding liquid water to a dispenser, at least a portion of which being located on a refrigerator door, configured to dispense liquid water and frozen water as ice, the refrigerator door being configured to open to enable frontal access and close to inhibit frontal access to at least a portion of the refrigerating compartment; and means for guiding liquid water to a branch point, at which water branches to interface with the ice maker and the dispenser, the branch point being located proximate to a wall of the refrigerating compartment, wherein the means for guiding liquid water to the inlet of the ice maker comprises means for guiding liquid water along at least one wall of the refrigerating compartment without guiding water along a wall of a freezing compartment, and wherein the means for guiding liquid water to the dispenser comprises means for guiding liquid water along at least one wall of the refrigerating compartment without guiding water along a wall of the freezing compartment. 12.
