Abstract: A refrigerator having a cold air circulating apparatus includes: a main body, which is provided with a freezer compartment and a refrigerator compartment for preserving food items, and a temperature controlled compartment for preserving food items, separately from the freezer and the refrigerator compartments; a first cooling unit formed at the rear side of the freezer compartment for supplying cold air into the freezer compartment; a second cooling unit formed at the rear side of the refrigerator compartment for providing cold air into the refrigerator compartment; a cold air circulating device for circulating air inside the temperature controlled compartment by using the first cooling unit or the second cooling unit; and a control unit for controlling operations of the cold air circulating device to thereby regulate temperature inside the temperature controlled compartment, based on a user-set temperature for the temperature controlled compartment.

Abstract: A refrigerator including a temperature controlled compartment partitioned from the freezer compartment and the refrigerator compartment, a door for the temperature controlled compartment, a cooling unit installed in the temperature controlled compartment for supplying cold air to the temperature controlled compartment, a duct for defining a flow passage of the cold air to circulate the cold air supplied from the cooling unit within the temperature controlled compartment, a blower fan for blowing the cold air supplied from the cooling unit through the duct, and a control unit for generating control signals to drive the cooling unit and the blower fan so as to maintain a temperature in the temperature controlled compartment at a set temperature.
