PURPOSE:To reduce a maximum load and to prevent an abnormal rise of a discharge pressure by operating a cooling fan at higher number of revolutions than a normal value in synchronization with an operation of a compressor when detected temperatures of an evaporator and the atmosphere are equal to or higher than predetermined temperatures at an initial time of energizing a power source. CONSTITUTION:A refrigerator heat exchanges refrigerant discharged from a compressor 7 with the air supplied from a cooling fan 9a by a condenser to condense it, and then evaporates it by an evaporator. A temperature of the evaporator is detected by its special purpose temperature detecting means 15. Further, the air in the refrigerator is circulated by a circulating fan 12a while heat exchanging the air in the refrigerator with the evaporator. In this case, an outdoor temperature is detected by atmospheric temperature detecting means 19. At an initial time of energizing a power source, when detected temperatures of the evaporator and the atmosphere are equal to or higher than predetermined temperatures, the fan 9a is operated at higher number of revolutions than a normal value in synchronization with the operation of the compressor 7. Then, the fan 12a is operated at lower number of revolutions than the normal value only for a predetermined time. |
