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.

Abstract: A refrigerator is proposed. Due to a first heater provided in a damper assembly, a damper assembly or the connection portion of the damper assembly with a supply duct is prevented from freezing, and due to a second heater provided in the supply duct, the connection portion of the supply duct with the damper assembly or the inside of the supply duct is prevented from freezing.

Abstract: The present disclosure relates to a refrigerator. The refrigerator is configured to supply cool air to a refrigerating compartment, a freezing compartment, and an ice-making compartment by a single evaporator. A cool air passage for the ice-making compartment for supplying cool air to the ice-making compartment is configured to supply the cool air to an upper space in a cool air passage for the freezing compartment, which. supplies cool air to the refrigerating compartment and the freezing compartment, through an upper supply passage. Accordingly, since additional cool air is supplied to the cool air passage for the freezing compartment by using the upper supply passage, sufficient cool air is supplied to the refrigerating compartment and the freezing compartment by the single evaporator.

Abstract: A refrigerator and a method of controlling an operation thereof are proposed. In the refrigerator and method thereof, heat control of heaters for preventing a damper from freezing is performed according to at least any one condition set in consideration of a room temperature and refrigerator internal humidity. Accordingly, consumption of power due to unnecessary heat generation of the heaters may be reduced, thereby improving the power consumption.

Abstract: A refrigerator is proposed. In the refrigerator, a cool air passage for a freezing compartment which guides the flow of cool air to the freezing compartment, and a cool air passage for an ice-making compartment which guides the flow of cool air to the ice-making compartment partially share the cool air with each other. Through the sharing of cool air, the amount of cool air supplied to the freezing compartment is increased and sufficient cool air is supplied to the refrigerating compartment. Accordingly, sufficient cool air is supplied to the refrigerating compartment, the freezing compartment, and the ice-making compartment even with a single evaporator.
