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.

Refrigerator

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.

A friction apparatus is provided. The friction apparatus includes: a first member having a first surface; and a second member having a second surface that contacts the first surface, and moving while in contact with the first member, wherein at least one of the first surface and the second surface is hardened.

Friction apparatus

A duct structure of a refrigerator equipped with a door provided with a container space separated from an internal space of the refrigerator comprises: a multi-duct which is provided in a rear space in the internal space of the refrigerator and which discharges cool air into the internal space of the refrigerator while allowing air to flow upward; a connecting outlet which is provided in an upper end of the multi-duct; a connecting duct which communicates with the connecting outlet and which is extended in a front-rear direction; a front duct which is connected to a front end of the connecting duct and which is extended in a left-right direction; and a nozzle unit which is provided in a lower portion of the front duct and which discharges cool air into the container space of door.

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.
