Disclosed aspects relate to food freshness management. A freshness triggering event may be identified for a food item. The freshness triggering event may indicate that a criterion related to the food item has been achieved. A food freshness management action may be determined. The food freshness management action may be determined to respond to the freshness triggering event for the food item. The food freshness management action may be initiated. The food freshness management action may be carried-out with respect to the freshness triggering event for the food item.

A refrigeration device, a controller thereof, a user access terminal, a mobile terminal, a management terminal and a maintenance data management system. The controller for a refrigeration device includes: a controller input module configured to input and process maintenance data of an associated refrigeration device locally; a controller display module configured to display the maintenance data of the associated refrigeration device and a data processing interface; a controller storage module configured to store the maintenance data of the associated refrigeration device; and a controller data synchronization module configured to upload the maintenance data of the associated refrigeration device from the controller to a server periodically and/or in real time.

In order to permit use of a refrigerator by observant Jews during Holiday times, Normal and Holiday modes are established. During Holiday mode, repetitive fixed frequency and fixed duty cycle time cycles are established, each time cycle having on and off portions. During on cycle portions current flow through the refrigerator is permitted as determined by the refrigerator compartment temperature. During off cycle portions current flow is inhibited irrespective of refrigerator compartment temperature changes. Visible indicators inform users of the status of the current cycle portion, thereby advising them to open the refrigerator door only during off cycle portions.

Devices, methods, systems, and computer-readable media for a refrigeration rack monitor are described herein. One or more embodiments include a refrigeration system monitor, comprising a computing device with a memory storing instructions executable by a processor to: monitor real time performance metrics for a refrigeration system, wherein the real time performance metrics are received from temperature sensors, pressure sensors, and power sensors coupled to the refrigeration system, compare the real time performance metrics to a performance curve of devices associated with the refrigeration system, and generate health information for the devices associated with the refrigeration system based on the comparison.

A freezer includes a plurality of evaporators coupled to a payload bay with a multiplicity of coolant tubes in each evaporator, wherein each tube enters and then exits the payload bay, further comprising one or more cryogenic valves coupled to the coolant tubes; a pump to force coolant flowing through the evaporators; sensors coupled to the evaporators of the freezer to monitor vital parameters of the freezer; a processor; a wireless telemetry system to communicate one or more measured characteristics of the freezer in accordance with a service level agreement to a remote computer; and at least one notification component that provides a notification associated with a specific customer responsive to the measured characteristic of the service crossing a pre-defined threshold.

A method for controlling and managing a front door refrigerator using an application installed in a recording medium, according to an embodiment of the present invention, comprises: a step in which a user logs into a front door refrigerator control application installed in a recording medium including a mobile device, thereby allowing a main screen including menu display regions to be displayed on a display unit of the mobile device; and a step in which a storage information confirmation menu is selected from among a plurality of execution menus displayed in the menu display regions, wherein, when the storage information confirmation menu is selected, storage information of a product stored in the front door refrigerator is output to the display unit of the mobile device.

Embodiments of the disclosure enable contextual user experiences to be provided. A computing system receives sensor data from an appliance associated with a first user account, and analyzes the sensor data to identify a product and one or more second user accounts associated with the product. The second user accounts are used to aggregate product data associated with the product, and the product data is used to generate catalog data associated with the product. The catalog data includes one or more portions associated with the second user accounts and is transmitted to a client device associated with the first user account to prompt a first user to enter into a transaction associated with the product. Each portion of the catalog data is selectable to facilitate the transaction between the first user and a respective second user associated with the second user accounts.

A control method is provided for controlling a refrigerator that is connected to one or more electrical apparatuses, in which the refrigerator includes a door/drawer and a processor. The control method causes the processor to sense a change in an opened state or a closed state of the door/drawer and receive state information indicating an operation state of the one or more electrical apparatuses from the one or more electrical apparatuses, which are operable when the user is. The processor determines whether the user is cooking based on the received state information, and notifies the user of different information each time a change in the opened state or the closed state is sensed if a change in the opened state or the closed state is sensed when a determination is made that the user is cooking.

A control system automates control of reefer container resources in a reefer container system including a remote server computer in communication with reefer containers. Each reefer container includes a refrigeration system to control a climate of an interior cargo compartment of the reefer container. The refrigeration system includes a refrigeration circuit, including a compressor, a cooling space, and sensors to measure or estimate refrigeration system readings. The refrigeration system transmits refrigeration system parameter data; the remote server computer obtains the parameter data acquired during operation of the refrigeration system from at least one reefer container, and estimates a condition of the refrigeration system, including determining whether an alarm has been issued, or whether the estimated reefer container condition indicates that the refrigeration system requires maintenance or testing. A reefer container resource control unit receives the reefer container condition to automatically allocate the reefer container based on the reefer container condition.
