IPC: F25D11/00
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling a refrigerator for preventing a freezing of a switching chamber, by stabilizing a temperature of the chamber alterable for setting a temperature, and shortening a time until it becomes a set temperature. SOLUTION: A bottom heater 62 and aside heater 66 are respectively provided at a bottom and a side of a switching chamber 18. These heaters 62, 66 are always operated. A chilled gas amount is regulated by simultaneously opening or closing dampers for temperature control. Heating amounts of the heaters 62, 66 are different depending upon modes of a wine, cold storage, chilling or the like. The higher the set temperature of the mode is, the greater the heating amounts of the heaters 62, 66 become. The higher the indoor temperature is, the heating amounts of the heaters 62, 66 become large. If a temperature difference between the temperature before alteration of the chamber and a set temperature at the time of altering is -8 deg.C or higher, the heaters 62, 66 are operated at the maximum heating amounts.
