1. A refrigerator comprising:
a tray configured to form a cell having a space in which liquid is stored, the tray including a first tray configured to form a first portion of the cell, and a second tray configured to form a second portion of the cell and configured to move relative to the first tray;
a first tray cover formed as a separate component to the first tray and having a portion in contact with one side of the first tray;
a first tray supporter formed as a separate component to the first tray and having a portion in contact with another side of the first tray;
a cooler configured to supply cold air to the cell;
a liquid supply configured to supply liquid;
a supply valve configured to control a flow of the liquid to the space of the cell;
a heater configured to provide heat to the cell;
a heater case on which the heater is mounted and formed as a separate component to the first tray; and
a controller configured to control the supply valve,
wherein the controller is configured to:
move the second tray toward a first position after completion of an ice separation process,
control the cooler such that the cold air from the cooler is supplied to the cell before opening the supply valve,
initially open the supply valve to supply liquid to the space of the cell, after the cold air is supplied to the cell in a state in which the liquid is not provided in the space of the cell, and
control the heater after closing the supply valve.

6. A refrigerator, comprising:
a storage chamber;
a first tray provided in the storage chamber;
a first tray cover formed as a separate component to the first tray and having a portion in contact with one side of the first tray;
a first tray supporter formed as a separate component to the first tray and having a portion in contact with another side of the first tray;
a second tray provided in the storage chamber, wherein the first and second trays are configured to form a cell having a space in which liquid is stored;
a driver configured to move the second tray with respect to the first tray;
a cooler configured to cool at least one of the storage chamber or the cell;
a supply valve configured to control a flow of the liquid to the space of the cell; and
a controller configured to control the driver and the supply valve, wherein the controller is configured to:
move the second tray toward a first position after completion of an ice separation process,
control the cooler such that the cold air from the cooler is supplied to the cell before opening the supply valve,
initially turn on the supply valve after a predetermined time elapses, after moving the second tray to the first position in a state in which the liquid is not provided in the space of the cell, and
turn off the supply valve after the liquid is supplied to the space of the cell,
wherein the first tray includes a tray wall to form a portion of the cell and an extension wall extended from the tray wall, and
the extension wall is positioned between the portion of the first tray cover and the portion of the first tray supporter.

14. A refrigerator, comprising:
a tray configured to form a cell having a space in which liquid introduced into the space is phase-changed to ice, the tray including a first tray configured to form a first portion of the cell, and a second tray configured to form a second portion of the cell and configured to move relative to the first tray;
a first tray cover formed as a separate component to the first tray and having a portion in contact with one side of the first tray;
a first tray supporter formed as a separate component to the first tray and having a portion in contact with another side of the first tray; and
a supply valve configured to control a flow of the liquid to the space of the cell,
wherein the first portion of the cell includes a plurality of first cells, and the second portion of the cell includes a plurality of second cells,
the first tray includes a first communication hole provided to connect two adjacent first cells of the plurality of first cells, and
the second tray includes a second communication hole provided to connect two adjacent second cells of the plurality of second cells,
wherein the first tray includes a tray wall to form a portion of the cell and an extension wall extended from the tray wall, and
wherein the first tray is to pass through the first tray supporter and is to be in contact with the second tray, and the extension wall is in contact with the first tray supporter,
when the first tray is in contact with the second tray, the first communication hole is aligned with the second communication hole.
