A refrigerator, a refrigerator management system, and a control method for a refrigerator are capable of enhancing a power-saving effect of the refrigerator. The refrigerator includes: a main body having a storage chamber; a refrigeration cycle device including a compressor and a cooler; an air blower configured to blow cooling air cooled by the cooler to the storage chamber; a blowout volume control device configured to control a blowout volume of the cooling air to be blown out to the storage chamber; input means for receiving input of schedule information that is information about a schedule of a user; storage means for storing the schedule information input into the input means; and control means for controlling at least one of the compressor, the air blower, and the blowout volume control device based on the schedule information.

A device for dispensing items includes a cabinet, and a drawer within the cabinet. The drawer includes one or more compartments for storing items and a refrigeration system within the drawer. The refrigeration system is configured to maintain the one or more compartments in the drawer at a temperature below the temperature of the environment surrounding the cabinet. The drawer further includes thermal insulation at sides of the drawer and thermal insulation beneath the one or more compartments.

The present invention provides a transport container comprising; a first container having a first inner wall with a storage space for storing a transported object and a first outer wall provided on the outside of the first inner wall so as to form, with the first inner wall, a vacuum space therebetween; a first lid that is heat-insulating and is for removably sealing a first opening of the first container; a second container having a second inner wall with a space for storing the first container and the first lid and a second outer wall provided on the outside of the second inner wall so as to form, with the second inner wall, a vacuum space therebetween; a second lid that is heat-insulating and is for removably sealing a second opening of the second container; and a heat storage material for surrounding the transported object inside the storage space.

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.

Disclosed embodiments include portable devices for cold chain storage and methods of fabricating portable devices for cold chain storage. In an illustrative embodiment, a portable device for cold chain storage includes a container defining therein a storage region. The container includes an inner cylinder, and the storage region is defined coaxially inwardly of the inner cylinder. The inner cylinder includes phase change material disposed therein, and the phase change material is in thermal communication with the storage region. The inner cylinder also includes evaporative coils disposed therein. The evaporative coils are embedded in the phase change material. The container also includes a thermally insulated outer cylinder. An outer wall of the outer cylinder is disposed radially outwardly of an outer wall of the inner cylinder.

A mixed beverage production appliance has a first container which is configured for receiving a first fluid having a first freezing point and is able to be added to a mixed beverage and a second container which is separate therefrom and which is configured for receiving a second fluid having a second freezing point which is different from the first freezing point and which is able to be added to a mixed beverage. The two containers are connected into a refrigerating circuit of the mixed beverage production appliance which is configured such that the two containers are able to be subjected to different temperatures independently of one another.

The invention relates to a process for cooling the neck of bottles, wherein the neck of the bottle, positioned in the inverted position, is submerged in a mass of a solid heat-transfer medium, for example copper shot, which mass is cooled using a cryogenic fluid, for example liquid nitrogen, or else liquid CO.sub.2 or else a mixture of such fluids.

A refrigerator has a flow path structure formed by a heat-exchanger. The refrigerator includes storage compartments, and a cool air supplying unit provided at a rear of the storage compartments to supply cool air at the storage compartments, and the cool air supplying unit includes a heat-exchanger to divide a flow path at which cool air is provided to flow along the cool air supplying unit.

A refrigerator appliance is generally provided herein. The refrigerator appliance may include a cabinet, an icebox liner, an icemaker, an ice bin, and a circulation duct. The cabinet may define a one or more chilled chambers. The icebox liner may be attached to the cabinet. The icebox liner may define a sub-compartment in which the icemaker may be mounted. The ice bin may define a storage volume within the sub-compartment to receive ice from the icemaker. The circulation duct may extend within the sub-compartment in conductive thermal communication with the icemaker. The circulation duct may define an air passage in fluid communication with one of the chilled chambers and fluid isolation from the storage volume.

Provided are a refrigeration device and a cold water temperature control method for same. The control method comprises the following steps: controlling a refrigeration device to enter a heat preservation state (S1); detecting a water temperature in a water tank (10) in the refrigeration device (S2); and if the water temperature is greater than a first pre-set temperature, controlling the refrigeration device to carry out a refrigeration operation for a pre-set time so that the water temperature is less than a second pre-set temperature, and controlling the refrigeration device to stop the refrigeration operation after the pre-set time (S3), wherein the second pre-set temperature is less than or equal to the first pre-set temperature. The water temperature control is realized by means of a pre-set time, so that the temperature of cold water can be more precisely controlled.
