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.

Exemplary embodiments provide a refrigeration system having an interior space cooled by a plurality of cooling. Each cooling unit is capable of operating either synchronously when in communication with a control panel or under independent operation. Each cooling unit is modularly and replaceable without the use of tools by means of a quick connect system. The cooling units use a heat exchanger cooled by chilled water and make use of an electronic super heat control and electronic expansion valve to regulate the flow of refrigerant for improved efficiency.

A temperature controlled container includes a case which has a storage space formed therein; a thermoelectric element; a heat transfer body in communication with the thermoelectric element and facing the storage space. The heat transfer body includes a heat transfer case which has an enclosed space formed therein and is wider than the thermoelectric element, and includes a portion facing the thermoelectric element; a phase change material which is accommodated in the enclosed space; and a heat transfer body which is disposed in the heat transfer case so as to be positioned in the enclosed space. The heat transfer body has a first body portion which is in communication with the portion of the heat transfer case facing the thermoelectric element and a second body portion, and the first body portion in communication with the second body portion.

A refrigerator comprising an ice maker. The ice maker comprises: a housing providing an ice making space, a tray disposed in the ice making space and including a plurality of ice making cells, and a temperature sensor part disposed at the tray and configured to measure a temperature in the tray. The the plurality of ice making cells are provided in an odd number of columns greater than or equal to three, and the temperature sensor part is disposed (i) at a middle column among the columns, (ii) between ice making cells that are adjacent to each other, and (iii) below the tray.

A refrigerator is configured such that a controller may control the frost detecting operation to be differently performed on the basis of at least one of a room temperature and a set reference temperature. Thus, precise frosting detection may be performed and power consumption due to the frosting detection may be minimized, and power consumption efficiency may be improved.

A multiple drawer refrigerator, where each drawer is separately controllable to a temperature for a refrigerator or a freezer. Each drawer is isolated from all the other drawers, so that items in one drawer do not leech smells to another drawer, and so that opening one drawer does not release cold air from the other drawers.

Provided is a refrigerator. The refrigerator may include a first tray assembly defining a portion of an ice making cell and a second tray assembly defining another portion of the ice making cell. The refrigerator may further include a pusher provided with a first edge on which a surface configured to press one or more of the first and second tray assemblies is disposed to easily separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at an end of the bar. At least one of the pusher or the second tray assembly may move so as to change a relative position between the pusher and the second tray assembly.

An aspect of the present disclosure is to provide a refrigerator that enables a refrigerating chamber evaporator to replace an existing accumulator and defrost heater by improving a structure of the refrigerating chamber evaporator and a control method. The refrigerator in which a compressor, a condenser, a throttle, a freezing chamber evaporator, and a refrigerating chamber evaporator are connected through a refrigerant passage to form a refrigeration cycle. The refrigerating chamber evaporator may be provided between the freezing chamber evaporator and the compressor. A straight passage of a certain length may be formed at a refrigerant inlet side of the refrigerating chamber evaporator. A curved passage having a plurality of curved sections may be formed at a refrigerant outlet side of the refrigerating chamber evaporator.

Provided is a refrigerator. The refrigerator may include a first tray assembly defining a portion of an ice making cell and a second tray assembly defining another portion of the ice making cell. The one tray assembly of the first and second tray assemblies may include a first portion that defines at least a portion of the ice making cell and a second portion extending from a predetermined point of the first portion.

A cryogenic freezer features a dewar defining a storage space. A reservoir is positioned within or adjacent to the storage space and is configured to contain a cryogenic liquid with a headspace above the cryogenic liquid in a reservoir interior space that is sealed with respect to the storage space. A refrigeration module is in heat exchange relationship with the reservoir. A sensor is configured to determine a temperature or pressure within the reservoir. A system controller is connected to the sensor and the refrigeration module and configured so that the refrigeration module is adjusted to provide additional cooling to the reservoir when a pressure or temperature within the headspace increases.
