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 includes a cabinet, an evaporator, a shroud, a grille panel coupled to a front surface of the shroud, and a blower fan module disposed between the grille panel and the shroud and configured to blow the cool air from the evaporator toward a freezing compartment. The blower fan module includes an installation frame defining a first plane that faces a rear surface of the grille panel, and a second plane that faces the front surface of the shroud, a hub part that is rotatably coupled to the second plane of the installation frame and faces an inlet hole of the shroud, and a blower impeller disposed in the hub part.

Abstract: A method, which is for controlling a temperature of a refrigerating compartment, includes cooling the refrigerating compartment, cooling the freezing compartment, determining a temperature of the refrigerating compartment, and based on the temperature of the refrigerating compartment, controlling the refrigerating compartment to a constant temperature range by controlling opening and closing of first and second passages of a three-way valve of the refrigerator to alternate cooling the refrigerating compartment and cooling the freezing compartment.
