A freezer case includes a refrigeration system and a controller. The controller is configured to store a plurality of setpoint instruction sets associated with a plurality of possible operating modes, select a current operating mode from the plurality of possible operating modes, assign a value for the superheat setpoint by executing the setpoint instruction set associated with the current operating mode, control the refrigeration system in accordance with the superheat setpoint.

Apparatus are provided for preventing the formation of ice crystals in a biological sample containing a non-Newtonian fluid as a cryopreservation medium. The apparatus may be used to prevent ice formation during cryopreservation of biological samples, or during warming of cryopreserved biological samples, by changing the viscosity of the non-Newtonian fluid. The apparatus (200) comprises a housing (202) for a container (212) containing the biological sample (214) and the non-Newtonian fluid, and a device (204) for inducing a change in viscosity of the cryopreservation medium. The change in viscosity may be increased by inducing shear thickening of the cryopreservation medium, or the change in viscosity may be decreased by inducing shear thinning of the cryopreservation medium. Possible viscosity-changing devices comprise a tapping device, a piston, a rotating device, a compression device, a sound generating device, a permanent magnet or a electromagnetic field generating device. The apparatus may further include a temperature control device.

The present invention provides a refrigerator, comprising a storage compartment and a mixed air passage. Both ends of the mixed air passage have air inlets, the middle portion of the mixed air passage comprises a mixed air outlet communicating with the storage compartment, and the mixed air passage is configured to receive air flows from the two air inlets such that two air flows enter the storage compartment in a mixed manner via the mixed air outlet. The refrigerator of this invention comprises a mixed air passage, so that the air in an area of the storage compartment with a relatively high temperature can enter the mixed air passage earlier than external air or the air in the storage compartment with a relatively low temperature. Then, the two air flows are blown to the storage compartment in a mixed manner, realizing even temperature distribution in the storage compartment.

Systems and methods for an actively cooled container comprising: a power subsystem; an active cooling subsystem; and a control subsystem are provided. In some embodiments, the control subsystem is configured to: determine that additional cooling is needed; cause the active cooling subsystem to cool the actively cooled container below a lower limit; determine to end the additional cooling; and cause the active cooling subsystem to cool the actively cooled container at or above the lower limit. In this way, the best balance between a fast cooldown time and not damaging (e.g., through freezing) the product load (e.g., beverages), is achieved.

A beverage cooling device including a housing having a top wall, a side wall, and a cavity. A motor is operatively connected to a power supply within the housing. A container engagement member is rotatably coupled to the motor and configured to receive torque from the motor when the motor is actuated. The container engagement member includes an aperture for receiving an inserted beverage container and a plurality of spring members configured to deform upon insertion of the beverage container into the aperture and to provide a gripping force upon the beverage container.

Beverage chillers are disclosed. A beverage chiller may include a container platform that receives a beverage container and a chiller tank. The chiller tank may have a central axis and may have an agitator. The chiller tank may be filled with water. A conveyor may move the container platform and beverage container into the chiller tank. The container platform and beverage container may rotate in a first direction in the chiller tank and the agitator may rotate the water in a second direction.

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.

A control method of a refrigerating and freezing device and a refrigerating and freezing device are provided. The refrigerating and freezing device includes a cabinet defining a storage compartment. The control method includes a refrigerating operation step, a foodstuff determining step, and a cooling operation step. The refrigerating operation step is to control a temperature of the storage compartment to be within a first preset temperature range. The foodstuff determining step is to determine whether a new foodstuff is put into the storage compartment. The cooling operation step is to, when a new foodstuff is put into the storage compartment, cool the storage compartment. Since the temperature of the new foodstuff is greater than that of the original foodstuffs in the refrigerating and freezing device, cooling the storage compartment changes a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the new foodstuff, and the storage temperature is more convenient for the preservation of the new foodstuff and ensures good storage conditions for the newly put foodstuff. Furthermore, the preservation effect on the original foodstuffs will not be affected, and the preservation effect of the refrigerating and freezing device on the foodstuff is enhanced.

The present description concerns a gas cooling cell, comprising: a chamber; at least one opening in the chamber, of access to a treatment space internal to the chamber; at least one door for closing the opening; and a system (4), internal to the chamber, comprising at least one wall (42) mobile between a first position where this wall forms a screen between the opening and the treatment space, and a second position where said wall clears the access to the treatment space from the opening.

This invention describes a device that is able to promote the rapid cooling/freezing of liquids and pasty and solid foods in general, where it is formed by several components that enable the action of cooling/freezing. Additionally, this invention describes that this device can incorporate the additional function of a refrigerator, through direct coupling of a thermal box to the cooling system of the device.
