Abstract: A refrigerator of the present invention comprises: a storage chamber for storing food; a cool air supplying means for supplying cool air to the storage chamber; a first tray which forms a part of an ice-making cell in which water is phase-changed to ice by the cool air; a second tray which forms another part of the ice-making cell and can be in contact with the first tray during an ice-making process; a water supply valve for adjusting a flow of the water supplied to the ice-making cell; a water supply amount detector for detecting the amount of water supplied to the ice-making cell; and a controller for controlling the water supply valve. The controller controls the water supply valve to supply water to the ice-making cell as much as a first reference water supply amount, for supplying water to the ice-making cell at a water supply position of the second tray. After finishing the water supply as much as the first reference water supply amount, the controller moves the second tray to an ice-making position and determines whether the water supply amount of the ice-making cell has reached a target water supply amount by using the water supply amount detector. When the water supply amount of the ice making cell has reached the target water supply amount, the controller starts ice-making, and when the water supply amount of the ice making cell has not reached the target water supply amount, the controller moves the second tray back to the water supply position and controls the water supply valve to supply water as much as a second reference water supply amount which is less than the first reference water supply amount.

Abstract: The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of ice-making cells; a second tray assembly forming the other part of the ice-making cells; and a heater. In order to reduce the transfer heat, which is transferred from the heater to any one of the first and second tray assemblies, to ice-making cells formed by the other tray assembly, the one tray assembly may comprise a first part forming at least a part of the ice-making cells. The degree of heat transfer of the first part may vary along the outer circumferential surfaces of the ice-making cells.
