Refrigerator

A refrigerator comprising:

• a cabinet defining a storage space;
• a door configured to open or close the storage space;
• an evaporator provided in the storage space and configured to supply cold air to the storage space;
• a duct assembly provided above the evaporator, extending in a vertical direction, and configured to guide the cold air supplied to the storage space;
• a door supply duct coupled to the duct assembly and configured to guide a part of the cold air flowing through the duct assembly to be supplied to the door;
• and
• a fan motor assembly that is coupled to a lower end of the duct assembly and that is configured to suction air cooled by the evaporator and blow the suctioned air into the duct assembly,
• wherein the duct assembly defines a first passage and a second passage that are spaced apart from each other,
• wherein the second passage comprises:
• a main passage configured to supply the cold air to the storage space, and
• a sub-passage branched from the main passage and coupled to the door supply duct, and
• wherein, based on the cold air being supplied to the second passage, a flow rate of the cold air supplied through the second passage is greater than a flow rate of the cold air supplied through the first passage.
