PROBLEM TO BE SOLVED: To prevent operational instability in case of stopping a refrigerator for a long time at the time of low atmospheric temperature by deciding number of operating fans for a condenser in response to a detected temperature of an atmospheric temperature sensor. SOLUTION: An atmospheric temperature sensor 12 for detecting a temperature of the atmosphere sucked to a condenser 2 is provided. The detected temperature is input to a number-of-operating fans deciding means 21 mounted at a fan controller 20. The number of operating fans is decided in response to the atmospheric temperature based on a control rule stored in a control rule memory means 24, and output to respective fan motors 9A, 9B, 9C. The number of the operating fans is reduced in response to the detected temperature of the sensor at the time of restarting after the atmospheric temperature is low and they are stopped for a long time, and numbers of revolutions of the operated fans are reduced. Accordingly, since high pressure can be raised and hence a high and low pressure difference of a predetermined value or more can be maintained, a refrigerator can be stably operated. |
