A supercooling refrigerator (1000) including: a refrigerator body (100); a door (200) for opening and closing one side of the refrigerator body (100); an accommodating portion (400) provided inside the refrigerator body (100) and seated with an object (M) to be stored; a cooling duct (600) including a fan for taking in air in the refrigerator body (100) and discharging the air, and an evaporator (630) for cooling the air discharged from the fan; and a cool air supply duct (700) formed with a cool air discharge port (710) through which the air cooled through the cooling duct (600) is discharged into the refrigerator body (100), the fan being a cross flow fan (620) including a plurality of discs (622), and a plurality of blades (623) disposed between the discs (622) along outer circumferential surfaces of the discs (622).

A refrigerator appliance is provided herein. The refrigerator appliance may include a cabinet, a door, a secondary liner, and a heat exchange case. The cabinet may include an internal liner defining a freezer chamber and a fresh food chamber. The door may be attached to the cabinet. The secondary liner may be attached to the cabinet and define a sub-compartment in fluid isolation from the freezer chamber and the fresh food chamber. The heat exchange case may be attached to the internal liner at the freezer chamber in conductive thermal communication therewith. The heat exchange case may at least partially define a convection compartment along a portion of the internal liner. The convection compartment may be defined in fluid isolation from the freezer and in fluid communication with the sub-compartment.

A refrigerator may include a cabinet having a freezer compartment. An evaporator supplies cold air to the freezer compartment and an evaporator cover covers the evaporator. The evaporator cover has a supercooling passage for flowing some of cold air that has exchanged heat through the evaporator to a supercooling compartment of the freezer compartment. A cold air duct directs the other of the cold air that has exchanged heat through the evaporator to a top storage space over the supercooling compartment. A cold air guide device guides cold air in the cold air duct to a bottom storage space under the supercooling compartment.

A refrigerator includes: an inner case having a storage chamber; a thermoelectric module including a thermoelectric element and a cooling sink; a fan configured to circulate air, to the storage chamber; a fan cover configured to cover the fan and having an upper discharge hole, a lower discharge hole, and an inner suction hole formed between the upper discharge hole and the lower discharge hole; a first receiving member disposed in the storage chamber; and a second receiving member disposed over the first receiving member to be spaced apart from the first receiving member. At least a portion of each of the inner suction hole and the lower discharge hole faces a portion between the first receiving member and the second receiving member, and at least a portion of the upper discharge hole faces a portion between a top surface of the storage chamber and the second receiving member.

A refrigerator includes a refrigerating compartment configured to preserve food, the compartment including a plurality of walls forming a cavity, a door coupled to the compartment configured to cover the refrigeration space when in a closed position, and a passageway positioned on at least one of the walls and the door such that air within the cavity is in fluid communication with air outside the cavity when the door is in the closed position.

A blower having improved efficiency by minimizing a distance between an end of a blade and a cold air suction hole, and a refrigerator including the blower includes a body having a storage compartment including a refrigerator compartment and a freezer compartment, an evaporator provided behind the storage compartment and configured to generate cold air, and the blower configured to supply the cold air generated by the evaporator into the freezer compartment, wherein the blower includes a suction member having a cold air suction hole and a fan unit configured to supply cold air introduced through the cold air suction hole into the freezer compartment, and having an interference prevention portion separated from the suction member to prevent interference with the suction member, and a water repellent portion treated with a water repellent is provided on a surface of the suction member adjacent to the interference prevention portion.

An air duct is provided for a refrigerator having an enclosure and a refrigeration system with a fan for generating a cooling airflow. The air duct includes an air inlet fluidly couplable to and arranged for receiving the cooling airflow from the refrigeration system. An air outlet is downstream of the air inlet, and arranged to direct the cooling airflow from the refrigeration system into the enclosure in a first direction. A diverter is located between the air inlet and the air outlet and configured to divert a portion of the cooling airflow into the enclosure in a second direction different to the first direction.

An aseptic ice making system includes an ice making system to receive water from a water supply. The ice making system includes an ice producing subsystem to produce ice and a positive air pressure subsystem to maintain a positive air pressure environment within the ice making system.
