Abstract:
A refrigerator having a refrigerator compartment (102) and a freezer compartment (103) both defined therein, said refrigerator compartment (102) having a low-temperature storage chamber (133) of a temperature lower than that of said refrigerator compartment (102), said refrigerator comprising:a compressor (111), a condenser (112), a first throttling device (113), a channel control valve (122), a refrigerator cooling unit (110), and a freezer cooling unit (108) connected in series to form a refrigerating cycle, said refrigerator cooling unit (110) and said freezer cooling unit (108) being accommodated in said refrigerator compartment (102) and said freezer compartment (103), respectively;a second throttling device (124) connected in parallel with said refrigerator cooling unit (110);a first air fan (109) for sending cold air heat-exchanged by said refrigerator cooling unit (110) to said refrigerator compartment (102);a second air fan (107) for sending cold air heat-exchanged by said freezer cooling unit (108) to said freezer compartment (103);a suction duct (115) for introducing air inside said refrigerator compartment (102) to said refrigerator cooling unit (110);a discharge duct (116) for introducing air cooled by said refrigerator cooling unit (110) into said refrigerator compartment (102) and into said low-temperature storage chamber (133); andan electrically-operated damper (140) accommodated in said discharge duet, wherein when said electrically-operated damper (140) is opened, an amount of air to be introduced into said low-temperature storage chamber (133) is greater than an amount of air to be introduced into said refrigerator compartment (102).
