Claim 7:
8. The refrigerator of claim 1, comprising:
a compressor that circulates a refrigerant;
a cooler through which the refrigerant passes;
a cooling fan that blows cold air, which is air cooled by the cooler, toward the cooling/heating chamber;
a damper that is disposed on a flow passage between the cooling/heating chamber and the cooling fan, for controlling a flow rate of cold air flowing into the cooling/heating chamber by opening and closing; and
a temperature sensor that measures an internal temperature of the cooling/heating chamber, wherein
during the zone heating operation, the internal temperature of the cooling/heating chamber is maintained at the first cooling preservation temperature that is the temperature in the normal operation, by executing output control of the compressor, rotation speed control of the cooling fan, and opening/closing control of the damper, based on a result of measurement by the temperature sensor.
