Abstract:
1. A refrigerator having a cold air circulating apparatus, comprising: 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, wherein the cold air circulating device includes: a first cold air duct, installed between the first cooling unit and the temperature controlled compartment, for guiding the cold air from the first cooling unit to the temperature controlled compartment; a first damper, installed in the first cold air duct, for selectively introducing the cold air from the first cooling unit to the temperature controlled compartment under a control of the control unit; a second cold air duct, installed between the second cooling unit and the temperature controlled compartment, for guiding the cold air from the second cooling unit to the temperature controlled compartment; and a second damper, installed in the second cold air duct, for being opened or closed for selectively introducing the cold air from the second cooling unit to the temperature controlled compartment under a control of the control unit.
