Claims

[Scope of utility model registration request]

Equipped with a compressor whose operation and stop are controlled by opening and closing the freezer thermostat, an on-off valve which is controlled by opening and closing the refrigerator thermostat, a first capillary tube, an evaporator for the refrigerator compartment, and an evaporator for the freezer compartment. The second refrigeration circuit has a second refrigeration circuit equipped with a second capillary tube and a second on-off valve connected to the wake of the second capillary tube and controlled by opening and closing of a refrigerator room thermostat. The refrigeration circuit has one end connected between the condenser and the first on-off valve, and the other end on the second on-off valve side between the evaporator for the first freezer compartment and the evaporator for the refrigerator compartment. A refrigerator that is connected to the refrigerator and that, during defrosting, stops power supply to the refrigerator compartment thermostat using a defrosting timer of the freezer compartment evaporator prior to defrosting.
