PROBLEM TO BE SOLVED: To enhance energy efficiency by reducing the amount of power consumption and to improve safety in a refrigerator-freezer by using a flammable refrigerant for preventing global warming. SOLUTION: A device for adjusting the amount of restriction for changing the amount of restriction of the restriction section of a freezing cycle, a chill circulation control device for switching an air duct for feeding chill to a storage, and a temperature detection means for each storage, are provided. Thus the cooling operation of the refrigerator-freezer is independently and alternately performed according to detection and setting temperatures. |
