PROBLEM TO BE SOLVED: To preserve a food while suppressing degradation by making a switch to a storage compartment of temperature zone above the maximum ice crystal generation zone and above the freezing temperature zone, i.e., a new temperature zone freezing compartment, thereby prolonging the preservation period of food as compared with an ice box. SOLUTION: Chill is supplied through a new temperature zone freezing compartment air duct to a new temperature zone freezing compartment. A temperature detecting thermistor (temperature detecting means) is disposed in the new temperature zone freezing compartment. When the temperature detecting thermistor exceeds a specified temperature, a chill outlet is opened by opening a damper and temperature in the new temperature zone freezing compartment is regulated by supplying chill. Since foods in the new temperature zone freezing compartment are preserved in a temperature zone from -5 deg.C to -10 deg.C, for example, the foods are not frozen hard as in case of freezing compartment but frozen soft enough to be cut by means of a kitchen knife or a hand. Furthermore, foods can be preserved for a week or longer under better conditions as compared with an ice box. |
