Disclosed is an artificial intelligent refrigerator including a cold-storage chamber; a temperature information receiver for receiving external temperature information of a location in which a purchased item is located; an arrival time information receiver for receiving expected arrival time information to be taken until the item is stored in the cold-storage chamber; and a temperature controller for setting in advance a target cooling temperature of the cold-storage chamber for the item based on an artificial intelligence (AI) processor in which a neural network model is mounted before the item is stored in the cold-storage chamber. Here, the temperature controller inputs the external temperature information and the expected arrival time information to the neural network model to estimate a temperature change of the item and sets in advance a target cooling temperature of the cold-storage chamber based on an estimated temperature change of the item.

A freezer case includes a refrigeration system and a controller. The controller is configured to store a plurality of setpoint instruction sets associated with a plurality of possible operating modes, select a current operating mode from the plurality of possible operating modes, assign a value for the superheat setpoint by executing the setpoint instruction set associated with the current operating mode, control the refrigeration system in accordance with the superheat setpoint.

A cryogenic freezer features a dewar defining a storage space. A reservoir is positioned within or adjacent to the storage space and is configured to contain a cryogenic liquid with a headspace above the cryogenic liquid in a reservoir interior space that is sealed with respect to the storage space. A refrigeration module is in heat exchange relationship with the reservoir. A sensor is configured to determine a temperature or pressure within the reservoir. A system controller is connected to the sensor and the refrigeration module and configured so that the refrigeration module is adjusted to provide additional cooling to the reservoir when a pressure or temperature within the headspace increases.

An icemaker for a refrigerator appliance is provided. The icemaker includes an icemaker box selectively closeable by a door. An outer gasket is positioned about an inner edge of the door. A sealing gasket is positioned around a center portion of the door. A plurality of protrusions extend from a box rim of the icemaker box. A liner is aligned with and spaced apart from the box rim. A first gasket and a second gasket are positioned between the box rim and the liner.

A control method for controlling a refrigerator includes a first step for driving a compressor for compressing a refrigerant and a fan for moving air, a second step for driving the compressor and stopping the fan, a third step for stopping the compressor and driving the fan, and a fourth step for stopping the compressor and the fan.

Provided is a food monitoring apparatus including at least one light source configured to selectively radiate light of a first wavelength band and light of a second wavelength band that is different from the first wavelength band to food, at least one image sensor configured to obtain a visible image of the food and a hyperspectral image of the food based on light scattered, emitted, or reflected from the food, and at least one processor configured to obtain first information of the food based on the visible image, and to obtain second information of the food based on the first information and the hyperspectral image.

A refrigerator appliance assembly includes a cabinet having at least one chamber for receipt of an item, a door permitting access to the at least one chamber, a temperature port within the at least one chamber, and a temperature probe communicatively coupled with the temperature port. The temperature probe is configured to generate one or more first temperature signals representative of an actual temperature of at least one of the item or the at least one chamber. The refrigerator appliance also includes a controller communicatively coupled to the temperature probe. Thus, upon receipt of the one or more first temperature signals, the controller determines the actual temperature of at least one of the item or the at least one chamber. Further, the refrigerator appliance also includes a user interface communicatively coupled to the controller. Accordingly, the user interface displays the actual temperature to a user and allows the user to adjust the actual temperature of at least one of the item or the at least one chamber to a desired temperature of the item.

A refrigerator according to an embodiment of the present disclosure includes a first storage compartment, a cavity, a heat source, a cold source, a water molecule freezing preventing device, and a controller configured to control an output of at least one of the heat source, the cold source, or the water molecule freezing preventing device, wherein the controller is configured to perform a first operation step to operate based on the first notch temperature for a cooling operation, a second operation step to operate based on a second notch temperature for a heating operation, and a third operation step to operate based on a third notch temperature for the cooling operation, the second notch temperature is higher than 0° C., and the third notch temperature is higher than the first notch temperature. Accordingly, it is possible to efficiently supply the cold or heat until reaching a supercooling maintenance section.

A method and device for operating a cryogenic tunnel involving the implementation of the following provisions: the measurement of a plurality of key parameters of the method, the division of these parameters into two groups of different parameters, the implementation of one or both of the two following actions on these key parameters: Anticipation actions on the parameters of the 1.sup.st group (in order to act in advance on an anticipated/expected deviation in the deep-freezing quality; and Retroactive actions (countermeasures) on the parameters of the second group, in order to rebalance a measured, effective drift in the quality of the exiting products.
