A refrigerator. When the air flow entering a refrigeration compartment (1) from a second sub-trunk (53) branched from a main trunk (51) for circulating cold air is reduced, the absolute humidity of air in a cooling chamber (4) where an evaporator (3) is located is decreased, and thus the air flow around the evaporator (3) is reduced, so that the absolute humidity of air entering a drying chamber (2) is decreased, and a better dehumidifying effect is achieved.
