wherein a refrigerator module includes:
a cabinet forming an appearance of the refrigerator module and having a plurality of storage chambers therein;
a door disposed for a storage chamber;
a radiational cooling plate forming a rear wall of the storage chamber, wherein the radiational cooling plate is disposed to block air communication between an interior of the storage chamber and an interior of another storage chamber, wherein the radiational cooling plate cools the interior of the storage chamber through radiational cooling;
a cold air circulating flow path disposed at a rear of the radiational cooling plate to supply cold air for heat exchange with the radiational cooling plate; and
a machine room for discharging cold air to the cold air circulating flow path and sucking the cold air that has exchanged heat with the radiational cooling plate,
wherein the cold air circulating flow path is inserted into the cabinet through an insertion hole formed to communicate with the outside of the cabinet on a top face or a bottom face of the cabinet.
