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 (121, 131); a damper configured to selectively block a flow of the cold air guided to the supply duct; one or more heaters (610, 620) 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; refrigerator internal temperature sensors (721, 722), respectively configured to detect a temperature in each storage compartment (121, 131); a refrigerator internal humidity sensor configured to detect humidity in any one of the two storage compartments (121, 131); and a controller configured to control at least any one operation of the compressor, the damper, and the one or more heaters (610, 620) 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 (721, 722), 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 (610, 620) 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 (610, 620) 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 (610, 620) to stop generating the heat regardless of the room temperature 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 (121, 131); a damper configured to selectively block a flow of the cold air guided to the supply duct; one or more heaters (610, 620) 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; refrigerator internal temperature sensors (721, 722), respectively configured to detect a temperature in each storage compartment (121, 131); a refrigerator internal humidity sensor configured to detect humidity in any one of the two storage compartments (121, 131); and a controller configured to control at least any one operation of the compressor, the damper, and the one or more heaters (610, 620) 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 (721, 722), and the refrigerator internal humidity sensor is satisfied a first condition for controlling the heaters (610, 620) 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 (610, 620) 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 (610, 620) to stop generating the heat regardless of the room temperature when the humidity in any one storage compartment falls within a first set humidity range.
