The invention provides a refrigerator. The refrigerator comprises a refrigerating chamber, a freezing chamber, a first varying temperature chamber arranged independent of the refrigerating chamber and the freezing chamber, at least one second varying temperature chamber contained in the refrigerating chamber, a refrigerating chamber air supply air channel formed behind the refrigerating chamber, a refrigerating fan, a refrigerating chamber air door, second varying temperature chamber air doors, a control unit used for receiving temperature information fed back by a refrigerating chamber temperature sensor and/or a second varying temperature chamber temperature sensor and selectively controlling the refrigerating chamber air door and/or the second varying temperature chamber air doors to be opened or closed, and a refrigerating unit used for receiving the temperature information fed back by the refrigerating chamber temperature sensor and selectively controlling a refrigerating evaporator to connect or disconnect a refrigerant loop. Compared with the prior art, the refrigerator enables temperature in the temperature area of the varying temperature chambers located in the refrigerating chamber to reach minus 7 DEG C and even lower while ensuring that temperature of the refrigerating chamber will not be too low. Meanwhile, the refrigerator has the effects of saving energy, reducing noise and prolonging the service life.
