ABSTRACT:
A refrigerator having a quick cooling system which can cool food stored therein quickly by operating a refrigerating cycle regardless of refrigerator compartment temperature. The refrigerator includes a time setting device and a control device. By using the time setting device, the desired completion time of the quick cooling operation is set. The control device determines a time at which the quick cooling operation is to be started by subtracting a predetermined time period for which the quick cooling operation is carried out from the desired completion time. The control device compares a present time with the quick cooling operation starting time, and when the present time has reached the quick cooling operation starting time, starts the quick cooling operation automatically. Quick cooling operation is automatically started and completed at the desired time, preventing cooled food from heating again, for example by defrosting operation before being taken out.
