PURPOSE:To reduce deterioration in quality of food stored in a refrigerator by a method wherein a plurality of cases having upper opened parts are installed in a freezing chamber, and a part of the openings of these cases is provided with a plurality of temperature sensing means for sensing a temperature of the freezing chamber. CONSTITUTION:When a temperature of the first temperature sensor 34a in a freezing chamber is increased up to a predetermined value (t1) deg.C, operations of a compressor and a blower are started. When the temperature is cooled down to a predetermined value (t2 deg.C, the operations of the compressor and the blower are stopped. This intermittent operation is repeated. Then, the freezing chamber is cooled to its predetermined temperature and kept at its value. Since the freezing chamber has a plurality of cases there, a flowing-out of cold air and flowing-in of hot air at the time of opening or closing the door are restricted. An entire temperature increase of the refrigerator as well as a local increase of temperature can be detected fast by a plurality of temperature sensing means 34a, 34b and 34c placed adjacent to the opening of each of the cases. In addition, when the temperature is more than a predetermined temperature, the cold air is continuously fed until the temperature returns to its predetermined temperature so as to restrict an increase in temperature. |
