Abstract: A 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 grille fan assembly, and the ice-making compartment is configured to be located any one refrigerating compartment door and to receive cool air from a freezing compartment side grille fan assembly with the freezing compartment. The refrigerating compartment side grille fan assembly is configured to supply a greater amount of cool air to the side where the ice-making compartment and the refrigerating compartment side grille fan assembly are located, and to perform cool air supply proportional to temperature influence provided from the ice-making compartment and the refrigerating compartment side grille fan assembly.

Abstract: A 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 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: 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.
