A refrigerator is provided. The refrigerator may include a main body having a storage compartment, a first door rotatably installed at a first side of the main body to open and close a first portion of the storage compartment, and a second door rotatably installed at a second side of the main body to open and close a second portion of the storage compartment. A first camera may be installed at the first door to take a picture of an interior of the first storage compartment during rotation of the first door, and a second camera may be installed at the second door to take a picture of the interior of the first storage compartment during rotation of the second door. A controller may combine plural pictures taken by the first camera and the second camera into a single corrected image of a region of the first compartment spanning from the first door to the second door.

The present disclosure acquires information on a cold insulator. The cold insulator includes: at least one cold storage material; a packaging unit configured to package the at least one cold storage material; one or more first temperature sensors disposed on the packaging unit; and a transmission unit disposed on the packaging unit to transmit a result of measurement performed by the one or more first temperature sensors to an external device.

Techniques for operating a transport refrigeration system with an energy storage device include producing a first output and a second output at an energy storage device (ESD), and converting the first output and the second output to a converted first output and a converted second output. The techniques also include supplying the converted first output and the converted second output to components of the transport refrigeration system, and operating the components of the transport refrigeration system using the converted first output and the converted second output.

A control system and a control method of refrigeration in a closed space based on computer vision are provided. An image of a food, temperature and humidity information in the closed space are collected, and a type of the food is identified according to the image. The image is processed through Euler video amplification when food is not packaged to obtain surface color distribution information of the food, a state of the food is determined according to the surface color distribution information and a historical learning result, and a state prompt corresponding to the state of the food is provided to a user. Temperature and humidity in the closed space are regulated according to the state of the food. The state of the food is determined according to storage time and a known quality guarantee period when the food is packaged, and another state prompt is provided to the user.

A refrigerator is provided having at least one internal refrigerated compartment in which a plurality of refrigeration zones are provided, wherein an environment in each refrigeration zone may be independently controlled using a user interface configured to receive a zone selection input from a user indicating one of the plurality of refrigeration zones in which the user desires to adjust the environment; a plurality of lights provided in the internal refrigerated compartment and disposed proximate to each of the plurality of refrigeration zones, wherein groups of the plurality of lights may be separately controlled for visually identifying each of the refrigeration zones; and a controller configured to receive a zone selection input from the user interface, identify a group of the plurality of lights that are disposed proximate the selected refrigeration zone, and control the identified group of the plurality of lights to visually confirm the selected refrigeration zone.

A refrigerator of this embodiment includes a housing that includes a storeroom, a door that is rotatably provided in the housing through a hinge portion and opens or closes an opening of the storeroom by the rotation, a connection line that is led out to the vicinity of the hinge portion, and a wireless communication apparatus that includes a wireless communication unit and is connected to the connection line.

A dynamic multi-zone anti-sweat heating system may be used in a refrigerator to reduce moisture on various surfaces of the refrigerator. Moreover, in some instances, the determination of when moisture is present and/or absent from a surface may be made based at least in part on detection of the presence or absence of an elevated thermal load on the surface while a heater is activated.

Methods of operation for refrigerator appliance configurations with a controller, a condenser, at least one evaporator, a compressor, and two refrigeration compartments. The configuration may be equipped with a variable-speed or variable-capacity compressor, variable speed evaporator or compartment fans, a damper, and/or a dual-temperature evaporator with a valve system to control flow of refrigerant through one or more pressure reduction devices. The methods may include synchronizing alternating cycles of cooling each compartment to a temperature approximately equal to the compartment set point temperature by operation of the compressor, fans, damper and/or valve system. The methods may also include controlling the cooling rate in one or both compartments. Refrigeration compartment cooling may begin at an interval before or after when the freezer compartment reaches its lower threshold temperature. Freezer compartment cooling may begin at an interval before or after when the freezer compartment reaches its upper threshold temperature.

Disclosed is a method of storing food in an artificial intelligent refrigerator including obtaining an image of a storage chamber through a camera installed in the storage chamber of the refrigerator; transmitting the obtained image to a server; receiving a recognition result of food newly stored in the storage chamber through AI image processing in the server from the server; and displaying notifying information related to the food in a display unit of the refrigerator based on the received result.

A refrigerator is provided having at least one internal refrigerated compartment in which a plurality of refrigeration zones are provided, wherein an environment in each refrigeration zone may be independently controlled using a user interface configured to receive a zone selection input from a user indicating one of the plurality of refrigeration zones in which the user desires to adjust the environment; a plurality of lights provided in the internal refrigerated compartment and disposed proximate to each of the plurality of refrigeration zones, wherein groups of the plurality of lights may be separately controlled for visually identifying each of the refrigeration zones; and a controller configured to receive a zone selection input from the user interface, identify a group of the plurality of lights that are disposed proximate the selected refrigeration zone, and control the identified group of the plurality of lights to visually confirm the selected refrigeration zone.
