PURPOSE: To shorten a time duration reaching a refrigeration keeping temperature by a method wherein a refrigerator fan is operated in sequence from a fast freezing operation while an inside area of the refrigerator shows an increased refrigerating temperature after the operation of the refrigerator is changed over from its fast freezing operation to the refrigeration keeping operation. CONSTITUTION: In the case that a fast freezing operation is completed and a refrigerating operation is started, a refrigerator temperature is naturally lower than the refrigerating temperature. Due to this fact, a first thermoswitch Th1 is kept released, a second relay X2 is kept at its unenergized state and a normal-closed contact point X2a is closed. Accordingly, a fourth relay X4 is energized, and a fan motor FM is operated through a third control system 13 of its normal-open contact point X4b. This state is continued until the refrigerator temperature is increased up to the refrigerating temperature and the first thermoswitch Th1 is closed. That is, at the beginning of the refrigerating operation, the fan motor FM is continuously operated from the fast freezing operation while a freezer is being stopped and this is operated continuously. With such an arrangement as above, the temperature is increased up to the refrigerating temperature with heat generation from the fan motor FM. |
