The controller 93 may detect the temperature in the freezer chamber 12, and when the thermostat 93 detects that the temperature in the freezer chamber 12 is lower than the set temperature, the thermostat 93 may detect the temperature in the first exhaust port 61 and the second. By controlling the damper 51 of the exhaust port 63 to be closed, air does not flow out from the first exhaust duct 53 and the second exhaust duct 55, and the cooling of the upper freezing chamber 12 is stopped, and the thermostat 93 When it detects that the temperature in the freezer chamber 12 is higher than the set temperature, the thermostat 93 controls to open the damper 51 of the first exhaust port 61 and the second exhaust port 63, and the cooled air is released. It flows out from the first exhaust port 61 and the second exhaust port 63, and further cools the freezing chamber 12.

According to the refrigerator 100 according to the embodiment of the present disclosure, the freezer compartment 12 is divided into the upper cooling chamber 121 and the lower cooling chamber 122 by providing a door panel, and a duct that can operate relatively independently is provided. One cooling chamber can complete the cooling work independently, and by providing the thermostat 93 and the damper 51, the refrigerator 100 controls the opening and closing of the ducts of the two cooling chambers according to the user's needs, and further two cooling chambers. The temperature can be controlled, the refrigerator 100 has a wider variety of usage patterns, and can meet the different usage needs of different users for the refrigerator 100.
