Abstract
Disclosed is a temperature control method for a refrigerator which can minimize a deviation in refrigerant compartment temperature while minimizing the power consumption of the refrigerator. The temperature control method includes the steps of (A) comparing a sensed temperature of a freezing compartment with a predetermined maximum freezing compartment temperature and a predetermined minimum freezing compartment temperature, respectively, thereby controlling a compressor and a circulating fan to be turned on or off such that the sensed freezing compartment temperature is ranged between the predetermined maximum and minimum freezing temperatures, (B) comparing, following the step (A), a sensed temperature of a refrigerating compartment defined with a plurality of refrigerating chambers therein, with a predetermined maximum refrigerating compartment temperature and a predetermined minimum refrigerating compartment temperature, respectively, thereby controlling a damper to be opened or closed and the circulating fan to be turned on or off such that the sensed refrigerating compartment temperature is ranged between the predetermined maximum and minimum refrigerating temperatures, and (C) discharging cold air into at least one of the refrigerating chambers when the damper is closed, and the compressor and the circulating fan are turned on.
