PURPOSE: To save the power by operating the refrigerating cycle in the rang of high COP. CONSTITUTION: The cooled air from an evaporator 14 is fed into a refrigerator chamber 10 and a freezer chamber 11 by the air supply effect of a supply fan 16 through a duct 18 for the refrigerator chamber and a duct 19 for the freezer chamber, a damper 20 for the refrigerator chamber and a damper 21 for the freezer chamber are arranged in the ducts 18, 19 respectively, and a branch duct 22 which by passes the damper 20 for the refrigerator chamber and whose flow passage resistance is large is arranged in the duct 18 for the refrigerator chamber. The damper 21 for the freezer chamber is opened and the damper 20 for the refrigerator chamber is closed until the temperature in the freezer chamber 11 reaches the lower limit set value for freezing, and when the temperature is in the deep freezer chamber 11 is dropped below the lower limit set value for freezing, the damper 20 for the refrigerator chamber is opened, and the damper 21 for the freezer chamber is closed. |
