ABSTRACT:
A refrigerator having an apparatus for controlling cooling intensity with one fan is disclosed. The refrigerator has ducts for supplying a freezing compartment and a fresh food compartment with cool air from a cooler, and one fan for blowing the cool air into the ducts. The ducts are selectively closed by a plate which pivots by a motor. Since the fresh food compartment is frequently used more than the freezing compartment, the plate is controlled to keep the fresh food compartment in a normal open state so as to supply the fresh food compartment with much more cool air. Thus, the distribution of the cool air in the freezing compartment and the fresh food compartment is effectively carried out.
