A method for controlling a refrigerator according to an embodiment of the present invention is characterized by comprising: a step for determining whether a defrosting period (POD) for defrosting a freezing chamber and a deep freezing chamber has elapsed; a step for, when it is determined that the defrosting period has elapsed, performing a deep cooling operation for bringing at least one among the temperature of the deep freezing chamber and temperature of the freezing chamber down to a temperature lower than a control temperature; and a step for defrosting the deep freezing chamber when the deep cooling operation is terminated, wherein, when the defrosting of the deep freezing chamber is started, a freezing chamber valve is closed to block cold air flow to the heat sink, the defrosting of the deep freezing chamber includes cold sink defrosting and heat sink defrosting performed after the cold sink defrosting is completed, and while the heat sink defrosting is being performed, a deep freezing chamber fan is driven to remove vapor generated during the cold sink defrosting.

A refrigerator is provided that includes a cabinet having a refrigerating compartment cooled by a refrigerating compartment evaporator and a refrigerating compartment fan, and a freezing compartment cooled by a freezing compartment evaporator and a freezing compartment fan. A filler is provided on one of pair of doors to shield a gap between the pair of doors when the pair of doors are closed, a filler heater is provided inside the filler, and a controller is configured to control operations of the refrigerating compartment fan, the freezing compartment fan, the filler heater, and a compressor. When the refrigerating compartment evaporator performs a defrosting operation, the controller turns on the refrigerating compartment fan and the filler heater in state in that the compressor turns off so that heated air inside the refrigerating compartment is circulated to pass through the refrigerating compartment evaporator.

A refrigeration manager that can be used to monitor and control disparate refrigeration systems at a site, even when the refrigeration systems are manufactured by different vendors. The refrigeration manager provides common views for the disparate refrigeration systems, which may help a technician more easily monitor and control the various refrigeration systems at a site.

A method for controlling a refrigerator according to an embodiment of the present invention is characterized in that, when the temperature of a freezing chamber is in a satisfactory temperature range, and a deep-freezing chamber mode is turned on such that a deep-freezing chamber cooling operation is being performed, the refrigerator is controlled to perform a cold air sagging prevention operation in which a fan of the freezing chamber repeatedly starts and stops at regular intervals.

The present technology relates to an information processing apparatus, an information processing method, and a food preservation apparatus each capable of more appropriately outputting a response concerning a food.

Provided is an information processing apparatus including a processing unit configured to: manage, as information regarding a food preserved in a preservation cabinet, food information containing ownership right information regarding an ownership right for each food; generate, in a case where information from an identified user contains the information regarding the ownership right, a response according to the ownership right information regarding a desired food of the user, on the basis of the managed food information; and output the generated response. The present technology is applicable to, for example, a device that makes up a food information management system.

A refrigerator fan device, comprising: a fan motor (10) which has a fan rotor (12) and which can be provided in an air duct between an air inlet (16), a refrigerator heat exchanger (15), and/or a refrigerator compressor (14) and an air outlet (18) on or in a refrigerator housing (20, 22), said fan motor (10) being connectable to a unit of the refrigerator, via electrical supply and/or control lines, wherein the fan motor (10) is realized as a brushless speed-controllable DC motor whose operating speed is or can be controlled as a function of an operating and/or used cooling space temperature signal of, the assigned or assignable refrigerator compressor.

Provided is a method of setting a system, the method being performed by a processor and including: (a) when receiving detection, by the sensor, of a first amount of goods equal to or larger than a first predetermined amount, displaying, on a display, a first screen prompting setting of a threshold amount of goods corresponding to a condition of trigger output; (b) when the sensor detects reduction of an amount of goods by at least a second predetermined amount after displaying the first screen, acquiring, as the threshold amount, a second amount of reduced goods; (c) after the threshold amount is acquired, displaying, on the display, a second screen for setting an action of the processing device; and (d) based on information on the action set after displaying the second screen, setting output contents to be output by the processing device upon satisfaction of the condition of trigger output.

The present disclosure relates to a refrigerator. The refrigerator according to an embodiment of the present disclosure includes: a compressor configured to compress a refrigerant; an evaporator configured to perform heat exchange using the refrigerant compressed by the compressor; an RF output device configured to output an RF signal to the evaporator for removing frost on the evaporator; and a controller configured to control the RF output device, wherein the controller is configured to: based on the RF signal, control the frost to phase change into a liquid by heat radiated from a plurality of metal fins of the evaporator; and after the phase change, control temperature of the phase changed liquid to increase by a water molecule movement based on the RF signal. Accordingly, defrosting may be performed using the RF signal.

A mobile vaccine carrier and method for operating the carrier. The carrier includes a housing having a lid preferably hinged to a base member, a vaccine storage member disposed within the housing and defining a storage space for a plurality of vaccine containers; and a cooling element disposed within the housing. The vaccine storage member further includes an inner container defining the storage space and having an inlet opening for placing and removing vaccine containers, a movable vaccine container holder and a cover member disposed on the lid. The vaccine container holder has an abutment portion abutting against an outer portion of the inner container so that the inlet opening is covered by the vaccine container holder and at least a part of the cover member protrudes into the storage space when the lid is in a closed position.

In a refrigerator control method according to an embodiment of the present invention, an operation corresponding to a freezer chamber load is performed when a heat load penetrates the inside of the freezer chamber, and the internal temperature of a deep-freezing chamber is differently set and controlled according to the on/off state of a deep-freezing chamber mode, and thus the input condition of the operation corresponding to the freezer chamber load can be differently set according to the on/off state of the deep-freezing chamber mode.
