ABSTRACT:
A method and apparatus for controlling a temperature in a refrigerating chamber of a refrigerator by sensing the temperature of cold-air by firsh and second temperature sensors disposed in the vicinity of cold-air suction and in feed ports, and finely adjusting the suction and feeding of the cold-air by fans disposed in the ports and dampers disposed in the suction port and a cold-air feed passage according to the sensed temperature conditions, whereby local over-refrigeration and cold-air drift phenomena developed in the refrigerating chamber are prevented and the temperature in the chamber is uniformly controlled.
