PURPOSE: A method for controlling the temperature of a refreshing chamber in a compatible typed refrigerator is provided to properly cool the refreshing cavity without a separate cooling duct. CONSTITUTION: After stopping a blowing fan, the temperature of a refreshing chamber located under a refrigerating cavity is read for being compared with an established value. If the compared value is not satisfied, a damper on the upper unit of a refrigerator is opened. Thus, the cooled air in a freezing cavity flows out of a returning passage for being supplied to the refreshing cavity. Therefore, the cooled air from the freezing cavity cools the refreshing cavity without needing a separate cooling duct. Then, producing cost is saved while reducing the insulating layer of the refrigerating cavity. Moreover, the entire cooling efficiency of the refrigerator is increased, because the refreshing cavity is cooled by using the cooled air flowed from the freezing cavity.
