The invention discloses a refrigerator and a
humidity control method for a refrigerating chamber of the refrigerator. The refrigerator comprises a refrigerator body, a door, a compressor, an
evaporator, a fan, a first temperature sensor, a second temperature sensor, a refrigerating chamber
moisture preserving mode selecting device and a controller, wherein the first temperature sensor is used fordetecting the temperature in the refrigerating chamber, the second temperature sensor is used for detecting the temperature of the
evaporator, the refrigerating chamber
moisture preserving mode selecting device is used for switching over the refrigerating chamber between a high
moisture preserving mode and a normal moisture preserving mode, and the controller is respectively connected with the first temperature sensor, the second temperature sensor, the compressor, the fan and the refrigerating chamber moisture preserving mode selecting device. A user can use the refrigerating chamber moisture preserving mode selecting device to select the moisture preserving
modes of the refrigerating chamber, after the moisture preserving
modes are selected, the controller judges needs of the user so asto switch over the refrigerating chamber between the high moisture preserving mode and the normal moisture preserving mode, different moisture preserving needs of the user can be met, and after the high moisture preserving mode is started by the user, the
humidity in the refrigerating chamber can be kept in a
high humidity value range.
