摘要： A refrigerator has a refrigerator compartment, a freezer compartment, and a low-temperature storage chamber formed in the refrigerator compartment and having a temperature lower than that of the refrigerator compartment. The refrigerator includes a compressor, a condenser, a first throttling device, a channel control valve, a refrigerator cooling unit, and a freezer cooling unit connected in series to form a refrigerating cycle. The refrigerator cooling unit and the freezer cooling unit are accommodated in the refrigerator compartment and the freezer compartment, respectively. The refrigerator also includes a second throttling device connected in parallel with the refrigerator cooling unit, a first air fan for sending cold air heat-exchanged by the refrigerator cooling unit to the refrigerator compartment, a second air fan for sending cold air heat-exchanged by the freezer cooling unit to the freezer compartment, a suction duct for introducing air inside the refrigerator compartment to the refrigerator cooling unit, a discharge duct for introducing air cooled by the refrigerator cooling unit into the refrigerator compartment and into the low-temperature storage chamber, and an electrically-operated damper accommodated in the discharge damper. When the electrically-operated damper is opened, an amount of air to be introduced into the low-temperature storage chamber is greater than an amount of air to be introduced into the refrigerator compartment.
