A refrigerator comprising: a refrigerator body having a first storage compartment and a second storage compartment a supply duct for guiding at least a portion of cold air generated by an operation of a compressor to flow to any one storage compartment ; a damper configured to selectively block a flow of the cold air guided to the supply duct ; one or more heaters configured to provide heat to at least any one of the damper or the supply duct ; a room temperature sensor configured to detect a room temperature (RT); refrigerator internal temperature sensors , respectively configured to detect a temperature in each storage compartment ; a refrigerator internal humidity sensor configured to detect humidity in any one of the two storage compartments ; and a controller configured to control at least any one operation of the compressor , the damper , and the one or more heaters when at least any one condition set on the basis of a sensing value of at least any one of the room temperature sensor , each of the refrigerator internal temperature sensors , and the refrigerator internal humidity sensor is satisfied characterized by the operating conditions set in the controller comprising at least one of: a first condition for controlling the heaters to generate the heat when the humidity in the storage compartment is higher than a first set humidity range and the flow of the cold air guided to the supply duct is blocked; a second condition for controlling the heaters to generate the heat when the humidity in the storage compartment is higher than a first set humidity range and the compressor is blocked; a third condition for controlling the heaters to stop generating the heat regardless of the room temperature (RT) when the humidity in any one storage compartment falls within a first set humidity range. a refrigerator body having a first storage compartment and a second storage compartment a supply duct for guiding at least a portion of cold air generated by an operation of a compressor to flow to any one storage compartment ; a damper configured to selectively block a flow of the cold air guided to the supply duct ; one or more heaters configured to provide heat to at least any one of the damper or the supply duct ; a room temperature sensor configured to detect a room temperature (RT); refrigerator internal temperature sensors , respectively configured to detect a temperature in each storage compartment ; a refrigerator internal humidity sensor configured to detect humidity in any one of the two storage compartments ; and a controller configured to control at least any one operation of the compressor , the damper , and the one or more heaters when at least any one condition set on the basis of a sensing value of at least any one of the room temperature sensor , each of the refrigerator internal temperature sensors , and the refrigerator internal humidity sensor is satisfied a first condition for controlling the heaters to generate the heat when the humidity in the storage compartment is higher than a first set humidity range and the flow of the cold air guided to the supply duct is blocked; a second condition for controlling the heaters to generate the heat when the humidity in the storage compartment is higher than a first set humidity range and the compressor is blocked; a third condition for controlling the heaters to stop generating the heat regardless of the room temperature (RT) when the humidity in any one storage compartment falls within a first set humidity range. <EOS>
