PROBLEM TO BE SOLVED: To prevent the in-refrigerator temperature from being influenced by a cooler during stoppage of the compressor of the compressor of a refrigerator or during the defrosting operation, and to stabilize the temperature of chill blown out of a cooler chamber, immediately after the operation of the compressor. SOLUTION: Chill is discharged into a refrigerator, after the temperature of the cooler 7 has become stable after operation of the compressor, by heat- insulating the cooler chamber 6 and the interior of the refrigerator. A damper 30 is arranged in a return air duct 15 which a moves toward the cooler chamber 6 from within the refrigerator, and the interior of the refrigerator and the cooler chamber 6 are demarcated during the stoppage of the compressor. The number of rotations of a blower is varied, depending the environment or the load, and also the unit natural frequency of a blower holder lying in a variable region is avoided. |
