Abstract: A refrigerator is proposed. The refrigerator includes a refrigerating compartment, a freezing compartment, and an ice-making compartment. The refrigerating compartment is configured to receive cool air from a refrigerating compartment side grill fan assembly, and the ice-making compartment is configured to be located in any one refrigerating compartment door and to receive cool air from a freezing compartment side grill fan assembly with the freezing compartment. The refrigerating compartment side grill fan assembly is configured to supply a greater amount of cool air to a space at a refrigerating compartment door without the ice-making compartment than the amount of cool air supplied to other spaces, and the freezing compartment side grill fan assembly is configured to supply a greater amount of cool air to a space communicating with a recovery duct for the ice-making compartment than the amount of cool air supplied to other spaces.
