A refrigerator includes a cabinet in which a storage space is formed; a main evaporator which is installed at one side of an inner portion of the storage space to cool the storage space; a case which is installed on the other side the inner portion of the storage space and defines a deep-freezing storage chamber; a drawer which is accommodated in the case so as to be retractable and withdrawable and in which food is stored; and a rapid cooling module which is provided on a rear side of the inner portion of the case and rapidly cools the deep-freezing storage chamber, in which the rapid cooling module may includes an auxiliary evaporator; and a thermoelectric device which is coupled to the auxiliary evaporator and cools the deep-freezing storage chamber through heat exchange by heat conduction.

The disclosure features various embodiments and aspects of a chest for quenching beverages. The chest can include a tank for holding a chilled mixture of ice and water, an ice maker adapted for making ice having an output for ejecting ice into a conduit in fluid communication with the tank, and a plurality of quench trays disposed above the tank for holding containers of beverages located in first and second positions. The trays can be filled with cold water by way of a conduit in fluid communication with the tank. The quench trays can include a compartment defined by a bottom and a plurality of walls, and defining therein a plurality of rows for aligning and containing a plurality of beverage containers. The drawers can further include at least one drain orifice configured to guide water out of the quench tray.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

An apparatus for the rapid cooling of packaged beverages that includes a thermally insulated immersion tank capable of containing a liquid refrigerant and an evaporator coil placed within the tank, where the container will be submerged while held by gripping means connected to a vertical rotation axis mounted on a vertically movable cart, both driven by driving means under the control of a control unit that commands a series of sequential steps such as driving the rotation of said axial rotation axis within a predetermined speed range and period of time followed by slowing down of the rotation of said axial rotation axis at a predetermined speed with a simultaneous vertical reciprocating movement of the container by means of the vertically movable cart for a predetermined period of time as many times as established by the control unit.

A method of and apparatus for accelerating the cooling of a beverage can and/or ice tray utilizing at least one body that presents a density and thermal conductivity, defines a standard beverage can and/or ice tray receiving receptacle configured to form a minimum contact surface area of engagement with at least one can and/or tray, and preferably further defines a series of thru-holes, so as to promote accelerated cooling through conduction, convection within a compartment.

An AI apparatus mounted in a refrigerator includes: an input interface configured to obtain environmental data; and a processor configured to provide the environmental data to an AI model, and to control the refrigerator to perform rapid refrigeration when a result of the AI model is greater than a first threshold. Accordingly, food stored in the refrigerator is stored in an appropriate condition without being spoiled.

A refrigerator is provided. The refrigerator includes a camera, a thermal imaging camera, a display, and a processor configured to acquire an image that photographed the inside of the refrigerator through the camera, identify an object included in the acquired image, acquire information on the temperature of the identified object based on a thermal image that photographed the inside of the refrigerator through the thermal imaging camera, and control the display to display information on the identified object and information on the temperature of the identified object.

Embodiments of the present disclosure generally relate to heat transferring apparatuses and methods. The apparatus and methods utilize the Joule-Thomson effect to remove heat from a heat source to facilitate cooling of the heat source. In one example, an apparatus receives heat from an object to be cooled. The received heat is used to pressurize a fluid. The pressurized fluid is depressurized through a venturi using vapor pressure as a driving force, thus cooling the fluid.

The present invention involves using either liquid nitrogen, dry ice, a gel-like solution of water and alcohol in an ice pack, or a combination of these in a method or device for rapidly lowering the temperature of multiple food and beverage products at the same time. The gel-like ice pack may be shaped around the food or beverage product to increase the surface area resulting in faster cooling. The device may also contain a scale, infrared temperature sensor, and bar code scanner for determining the initial weight, temperature, density, and type of food or beverage product to be cooled.

The disclosure features various embodiments and aspects of a chest for quenching beverages.
