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.

An insulated icemaking compartment is provided in the fresh food compartment of a bottom mount refrigerator. The icemaking compartment may be integrally formed with the liner of the fresh food compartment, or alternatively, may be modular for installation anywhere in the fresh food compartment. A removable bin assembly with a front cover normally seals the icemaking compartment to maintain the temperature in the compartment. A cold air duct formed in the rear wall of the refrigerator supplies cold air from the freezer compartment to the icemaking compartment. A return air duct directs a portion of the air from the icemaking compartment back to the freezer compartment. An air vent in the icemaking compartment directs another portion of air into the fresh food compartment. A control system provides for controlling refrigerator functions in a manner that promotes energy efficiency.

A refrigerator includes a first freezing cycle in which a first refrigerant circulates and having a first compressor, a first condenser, at least one first expansion mechanism, and at least one first evaporator, the first freezing cycle configured to cool freezing and refrigerating compartments, a freezing compartment sensor, a refrigerating compartment sensor, a second freezing cycle in which a second mixed refrigerant having a lower evaporation temperature than the first refrigerant circulates and having a second compressor, a second condenser, a second expansion mechanism, and a second evaporator, the second freezing cycle configured to cool a deep freezing compartment, a deep freezing compartment sensor, and a controller configured to operate the first freezing cycle and the second freezing cycle independently or simultaneously, thereby more efficiently cooling the freezing and refrigerating compartments and the deep freezing 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 a refrigerator cabinet, a freezer compartment disposed within the refrigerator cabinet, a fresh food compartment disposed within the refrigerator cabinet, an ice making compartment remote from the freezer compartment, and a fresh food compartment duct riser extending upwardly along a back of the fresh food compartment. The refrigerator further includes a shroud associated with a freezer compartment evaporator, an ice compartment supply duct leading from the shroud to the ice making compartment, and an ice compartment return duct leading from the ice making compartment towards the freezer compartment evaporator. The ice compartment supply duct has a split pathway and is positioned behind the fresh food compartment duct riser.

A refrigerator includes a cabinet having at least one door. A removable cooling module is coupled with an outer periphery of the cabinet. The removable cooling module includes an ice maker. A duct is in communication with the removable cooling module. Ice is produced by the ice maker and transferred through the duct to the refrigerator.

A refrigerator and a method of control thereof, whereby after driving of a compressor and a blower fan is stopped as temperatures of a refrigeration compartment and a freezer compartment are in a satisfactory state, opening/closing operations of a damper are repeatedly performed, so that cold air in the freezer compartment is supplied into the refrigeration compartment. Alternatively, if the temperature of the refrigeration compartment reaches an upper limit temperature, the repeated opening/closing operations of the damper are started. The repeated opening/closing operations of the damper are performed until the temperature of the refrigeration compartment reaches a lower limit temperature, so that a cooling operation of the refrigeration compartment is performed only once while the compressor is being driven.

A refrigerator appliance including a sealed cooling system with an evaporator in a frozen food storage chamber is presented. The evaporator includes a cover with movable louvers to allow chilled air to flow to the frozen food storage chamber in a first position and to block the flow in a second position, and a method of operation for such a refrigerator appliance.

A refrigerator according to one embodiment of the present invention comprises: a main body; a first storage chamber and a second storage chamber provided in the main body so that the front surfaces thereof are opened; an evaporator which is disposed inside the main body and which generates cold air; a first duct for supplying the cold air to the first storage chamber; a second duct for supplying the cold air to the second storage chamber; and a connecting duct for connecting the first duct and the second duct so as to allow the cold air generated by the evaporator to flow to the second duct, wherein the second duct includes a connecting port connected to the connecting duct, a discharge port through which the cold air is discharged, a discharge path for connecting the connecting port and the discharge port, and a connecting path for connecting the inside of the second storage chamber and the discharge path, the discharge path includes a minimum region in which the cross sectional area thereof in a vertical direction or a longitudinal direction is minimized, and the connecting path is provided to connect the inside of the second storage chamber and the minimum region.

A refrigeration appliance, particularly a domestic refrigeration appliance, has a thermally-insulating housing in which at least one first and one second inner chamber are separated from one another by a thermally-insulated wall. The first inner chamber is divided into a storage compartment and an evaporator chamber. A passage in the thermally-insulated wall connects the evaporator chamber to the second inner chamber. At least one closure element for controlling the air exchange is housed, in the passage, between the evaporator chamber and the second inner chamber.
