REFRIGERATOR AND CONTROL METHOD THEREFOR
First Claim
1. A refrigerator comprising:
- a main body forming a refrigerating chamber and a freezing chamber each including a temperature sensor;
a cooling unit having a compressor and an evaporator accommodated inside the main body and driven to circulate a refrigerant in the compressor and the evaporator to generate cold air around the evaporator;
a fan positioned inside the main body to supply the cold air to the freezing chamber;
a damper positioned between the freezing chamber and the refrigerating chamber and opened and closed to allow the freezing chamber and the refrigerating chamber to selectively communicate with each other; and
a controller controlling the damper for a predetermined damper opening time when a temperature of the freezing chamber reaches a freezing satisfaction temperature according to driving of the cooling unit.

Abstract
Disclosed is a refrigerator including a main body forming a refrigerating chamber and a freezing chamber each including a temperature sensor, a cooling unit having a compressor and an evaporator accommodated inside the main body and driven to circulate a refrigerant in the compressor and the evaporator to generate cold air around the evaporator, a fan positioned inside the main body to supply the cold air to the freezing chamber, a damper positioned between the freezing chamber and the refrigerating chamber and opened and closed to allow the freezing chamber and the refrigerating chamber to selectively communicate with each other, and a controller controlling the damper for a predetermined damper opening time when a temperature of the freezing chamber reaches a freezing satisfaction temperature according to driving of the cooling unit. A temperature change of the refrigerating chamber over time may be reduced and power consumption may be improved.

11. A method for controlling a temperature of a refrigerator which includes a cooling unit generating and supplying cold air and cools a refrigerating chamber and a freezing chamber configured to communicate with each other, the method comprising:
-
cooling the freezing chamber by the cooling unit in a state in which the refrigerating chamber and the freezing chamber are isolated; and when a temperature of the freezing chamber reaches a freezing satisfaction temperature, allowing the freezing chamber and the refrigerating chamber to communicate with each other for a predetermined communication time. - View Dependent Claims (12, 13, 14, 15)
