1. A modular refrigerator comprising:
a main cabinet including a cooling unit configured to generate cold air, and a connection duct that includes a first connection duct for cold air generated by the cooling unit to flow toward a right side of the main cabinet, a second connection duct for cold air generated by the cooling unit to flow toward an upper side of the main cabinet, and a third connection duct for cold air generated by the cooling unit to flow toward a left side of the main cabinet; and
a sub-cabinet that is selectively coupleable to the right side of the main cabinet, the upper side of the main cabinet, and the left side of the main cabinet, and including a cold air supply duct,
wherein the cold air supply duct includes:
a branch duct that branches into:
a first branch duct that, when the sub-cabinet is coupled to the right side of the main cabinet, communicates with the first connection duct to receive cold air generated by the cooling unit,
a second branch duct that, when the sub-cabinet is coupled to the upper side of the main cabinet, communicates with the second connection duct to receive cold air generated by the cooling unit,
a third branch duct that, when the sub-cabinet is coupled to the left side of the main cabinet, communicates with third connection duct to receive cold air generated by the cooling unit, and
a cold air discharge duct through which at least some of the air received by the branch duct is discharged into the sub-cabinet.
