PURPOSE: To speed up the return to a specified temperature of a freezer chamber and refrigerator chamber after a power failure by a method wherein when temperature sensors of a freezer chamber and condenser detect a set temperature or higher right after turning-on of a power, if an upper limit set pressure or higher is detected after a specified period of time has passed, the revolution number of a blowing fan is reduced for a period of time which is set in advance. CONSTITUTION: When both a detected temperature of a condenser temperature sensor 28 and a detected temperature of a freezer chamber temperature sensor 11 are set values or higher, i.e., it is detected that the outside air temperature is high, and the cooling is not done yet, after a specified period of time has passed after the detection, it is judged whether a detected pressure of a pressure- detecting means 25 is at an upper limit set value or higher or not. Then, the detected pressure is less than the upper limit set value, a normal control is performed. When the detected pressure is the upper limit set value or higher, i.e., under a state wherein an input load to a compressor (b) is too large, a current quantity which is connected to a blowing fan 9 by a control circuit 27 is reduced, and the revolution number of the blowing fan 9 is reduced, and that state is maintained until a previously set period of time passes. |
