Provided is a single-system air-cooled refrigerator (100), comprising a refrigerator compartment (10) and a freezer compartment (20). Also comprised are a first air passage (30) and a second air passage (40) which are separated from each other and connect the refrigerator compartment (10) and the freezer compartment (20), a first damper (31) and a second damper (41) that respectively open and close the first air passage (30) and the second air passage (40), and a refrigeration system and a control system. The control system is used to control the opening and closing of the first damper (31) and the second damper (41) so as to realize a first mode, a second mode and a third mode of operation of the refrigerator (100). The first operating mode is that neither the freezer compartment (20) nor the refrigerator compartment (10) are switched. The second operating mode is that the freezer compartment (20) is switched to the refrigerator compartment (10), and the third operating mode is that the refrigerator compartment (10) is switched to the freezer compartment (20).

A refrigerator, provided with: a storage compartment, at least divided into a refrigerating compartment (3) and a freezing compartment (4); a first evaporator (22), provided in a cooling chamber (8) connected to the storage compartment (3, 4) by means of a supply duct (9, 10); a second evaporator (23) provided inside of the freezing compartment (4); a switch valve (25), used for switching a refrigerant to flow or not flow to a refrigerant passage connected to the second evaporator (23); a fan (13), used for flowing air cooled by the first evaporator (22) from the cooling chamber (8) to the storage compartment (3, 4); a first duct shutter (11), inserted in the supply duct (9) connected to the refrigerating compartment (3); and a second duct shutter (12), inserted in the supply duct (9) connected to the freezing compartment (4). The refrigerator may prevent the storage compartment (3, 4) from becoming dry, thereby reducing defrost instances and power consumption.

A refrigerator, including a sealed refrigeration system, is provided herein. The sealed refrigeration system may include a compressor, a phase separator, and a rotatable heat exchanger. The phase separator may be in fluid communication with the compressor and include a separator body defining an inner face and an outer face. The inner face may define a refrigerant cavity. The outer face may be directed away from the refrigerant cavity opposite the inner face. The rotatable heat exchanger may include a thermally conductive body and a plurality of spaced planar fins. The thermally conductive body may be positioned about the outer face along a rotation axis. The planar fins may extend from the thermally conductive body in a radial direction away from the phase separator. The plurality of spaced planar fins may define an axial intake channel extending parallel to the rotation axis through one or more planar fins.

A refrigerator includes: a cabinet including a freezing chamber; an evaporator located at one side of the freezing chamber; a freezing chamber fan configured to supply cool air to the freezing chamber; an ice maker located in the freezing chamber and configured to perform ice-making; an ice bin located below the ice maker and separates and stores ice made in the ice maker; an ice detection device which detects whether or not the ice stored in the ice bin is full; and a control unit configured to control the freezing chamber fan according to a detection signal of the ice detection device. The control unit is configured to turn off the freezing chamber fan when ice-fullness is detected by the ice detection device and turn on the freezing chamber fan when the ice-fullness is not detected by the ice detection device.

A sectorized sub-zero cooling arrangement for refrigerators with direct access to the consumer products without having to open other cold storage chambers of the refrigerator. The sectorized cooling arrangement has at least one access door to at least one cold storage chamber. The access door is provided with a sectorized compartment with multiple storage sectors for containers of consumer products. The compartment is equipped with a partition wall that separates it from the cold storage chamber and at least one air extractor/blower with the cold storage chamber on the upstream side and the sectorized compartment on the downstream side.

A refrigerator appliance includes a cabinet defining a fresh food chamber and a freezer chamber and a plurality of camera assemblies mounted to the cabinet at a front portion of the fresh food chamber. The refrigerator appliance also includes a controller that is configured to perform a pixel statistical analysis of one or more video clips from the plurality of camera assemblies. The controller is configured to adjust one or both a brightness setting in the fresh food chamber of the refrigerator appliance and an exposure setting of the plurality of camera assemblies in response to the pixel statistical analysis of one or more video clips from the plurality of camera assemblies. The pixel statistical analysis of one or more video clips from the plurality of camera assemblies is triggered by an interaction with the refrigerator appliance.

A blast cell system is disclosed that includes a plurality of bays that are spaced across the blast cell, arranged to hold items to be cooled, wherein each bay is separated from each other bay so as to prevent cross-flow of air from one bay to another bay; a plurality of louvers, each covering a different bay of the plurality of bays; one or more flow sensors, temperature sensors, or both positioned to sense conditions for each of the plurality of bays; and a controller programmed to modulate open-closed positions of each of the plurality of louvers separately from others of the plurality of louvers, so as to allow different volumes of cooling air to flow through each respective bay.

A refrigeration control method and a refrigerator. The refrigeration control method for a refrigerator comprises: acquiring the refrigeration state of a first evaporator and the refrigeration state of a second evaporator; when the first evaporator performs refrigeration, acquiring the temperature of a second compartment; when the temperature of the second compartment is greater than the starting temperature of the second compartment and the difference therebetween is less than a first preset threshold, acquiring the temperature of a first compartment and determining whether the temperature of the first compartment is less than a preset first reference temperature, the first reference temperature being calculated according to the starting temperature of the first compartment and a set adjustment temperature; and when the temperature of the first compartment is less than the first reference temperature, switching the refrigerator into a state where the second evaporator performs refrigeration.
