A defrost or thaw measuring device has a dumbbell or hourglass-shaped rotatable compartment with a cavity, the cavity being partly filled with at least two phase change materials having different melting points. The measuring device may determine the time period of thawing at two or more temperature intervals in the refrigeration space.

A refrigerator provides visual information indicating a map of the refrigerator and technical operations of the corresponding regions. The refrigerator includes a voice recognition function using a proximity sensor. The refrigerator has input/output (I/O) management functions for foods stored therein. The refrigerator communicates with a peripheral device over a network.

The present invention provides a refrigerator and a control method thereof; the refrigerator includes: a constant temperature compartment, a cooling unit for cooling the constant temperature compartment, at least one tray located in the constant temperature compartment, a compartment temperature sensor for detecting a temperature in the constant temperature compartment, a tray temperature sensor for detecting a temperature of the tray, and a controller, and the cooling unit, the compartment temperature sensor and the tray temperature sensor are all communicatively connected with the controller.

A refrigerator is configured to enable a user to open doors of the refrigerator easily. The refrigerator performs a method for controlling the doors to prevent from opening due to a malfunction.

A controller within a refrigeration application controls temperature and humidity within a compartment of the refrigeration application. The controller may begin cooling the compartment based on a measured temperature value for the compartment. The controller may delay a starting time of an evaporator fan within the compartment based at least in part on a measured humidity value for the compartment. The controller may also adjust an operating time of a condenser fan based at least in part on the measured humidity value.

A temperature control system is used for controlling a temperature of a control target to a target temperature that changes with lapse of time. The system includes: a first adjustment apparatus that includes a first tank that stores a first heat transfer medium, adjusts the temperature of the first heat transfer medium to a first set temperature, and supplies the temperature-adjusted first heat transfer medium; a first circulation circuit through which the first heat transfer medium flows from the first adjustment apparatus to a first flow-through path and returns to the first adjustment apparatus; an adjustment section that adjusts an amount of heat supplied from the first flow-through path to the control target; a memory that stores a relation between the lapse of time and the target temperature; and a controller.

Provided is a refrigerator and control method for refrigerator and method for opening a refrigerator door. While a user is holding an object in both hands, a door may be automatically and additionally opened using another part of a body other than hands.

A refrigerator is configured to enable a user to open doors of the refrigerator easily. The refrigerator performs a method for controlling the doors to prevent from opening due to a malfunction.

A method to manage defrosting of a refrigeration plant provided with at least one compressor and at least one evaporator, including defining a plurality of defrosting modes, which can be selected by the manufacturer and/or by the end user, which are based on one or more functioning parameters of the refrigeration plant; such functioning parameters are detected by detection probes provided in the refrigeration plant such as pressure switches, thermostats, timing devices or other, associated with the compressor and/or the evaporator, or other; and memorizing the plurality of defrosting modes in an electronic device to manage the defrosting.
