PURPOSE: To make it possible to shorten a time for returning to predetermined temperatures of a freezing chamber and refrigerating chamber after service interruption by a method wherein the number of rotation of a blast fan is reduced for a preset period of time when both of the refrigerating chamber temperature and a room temper ature are higher than a set temperature immediately after throwing power supply while a pressure is higher than an upper limit set pressure after a predetermined period of time has elapsed. CONSTITUTION: When power is supplied, and the operation of a compressor 6 and a blast fan 9 are started, and when the detecting temperature of a room temperature sensor 16 as well as the detecting temperature of a refrigerating chamber temperature sensor 11 are higher than set values thereof immediately after the starting of the operation of the compressor 6 and the blast fan 9, or when the detecting pressure of a pressure detecting means 25 is higher than an upper limit value after a predetermined time has elapsed, or under a condition that the input load of the compressor 6 is excessive, a control circuit 27 reduces the number of rotation of the blast fan 9 and such a condition is maintained until a preset time is elapsed. Accordingly, the returning time of an inside temperature to a predetermined temperature will never be elongated after the energization is restarted whereby effects on stored foodstuff can be reduced. |
