A refrigerator comprising: a main body, a plurality of storage chambers including a freezing chamber, a switchable chamber and a refrigerating chamber, a duct allowing an air flow between the freezing chamber, a switchable chamber and the refrigerating chamber; a damper to control flow of air through the duct; a compressor; a condenser; a controller; a switchable chamber evaporator to cool the switchable chamber; a freezing chamber evaporator to cool the freezing chamber; a pair of switchable chamber capillary tubes (7, 8) connected with the switchable chamber evaporator; a bypass capillary tube connected with the evaporator connection path; a path switching device connected with the condenser, the switchable chamber capillary tubes (7, 8) and the bypass capillary tube to guide refrigerant to the switchable chamber capillary tubes (7, 8) or the bypass capillary tube; a switchable chamber fan to blow cold air to the switchable chamber evaporator and/or to blow the cold air in the switchable chamber and to the duct; a freezing chamber fan to blow cold air to the freezing chamber evaporator and/or to blow the cold air in the freezing chamber and to the duct; a switchable chamber temperature sensor for sensing the temperature of the switchable chamber; a freezing chamber temperature sensor for sensing the temperature of the freezing chamber; and a refrigerating chamber temperature sensor for sensing the temperature of the refrigerating chamber, wherein the controller is configured to close the damper when a temperature condition of the refrigerating chamber sensed by the refrigerating chamber temperature sensor is satisfied and to open the damper when the temperature condition of the refrigerating chamber is dissatisfied, and the switchable chamber evaporator is located at an upstream side of the freezing chamber evaporator in a refrigerant flow direction and is connected with the pair of switchable chamber capillary tubes (7, 8) by a joint path, the joint path includes a first path connected to a first capillary tube of the pair of switchable chamber capillary tubes (7, 8), a second path connected to a second capillary tube of the pair of switchable chamber capillary tubes (7, 8) and a common path connected with the first path and the second path, the common path being connected to the switchable chamber evaporator, wherein the controller is configured to operate the switchable chamber fan and the freezing chamber fan according to at least one of a temperature of the switchable chamber sensed by the switchable chamber temperature sensor, a temperature of the freezing chamber sensed by the freezing chamber temperature sensor and a temperature of the refrigerating chamber sensed by the refrigerating chamber temperature sensor. a main body, a plurality of storage chambers including a freezing chamber, a switchable chamber and a refrigerating chamber, a duct allowing an air flow between the freezing chamber, a switchable chamber and the refrigerating chamber;
