The present invention provides a refrigerator comprising: a cabinet having a storage chamber; a door for opening or closing the storage chamber; a case in which an inlet through which air flows from the storage chamber and an outlet through which the air is discharged to the storage chamber are formed; an evaporator provided inside the case for exchanging heat with the air to supply cool air; and a differential pressure sensor provided inside the case.

A refrigerator includes a first freezing cycle in which a first refrigerant circulates and having a first compressor, a first condenser, at least one first expansion mechanism, and at least one first evaporator, the first freezing cycle configured to cool freezing and refrigerating compartments, a freezing compartment sensor, a refrigerating compartment sensor, a second freezing cycle in which a second mixed refrigerant having a lower evaporation temperature than the first refrigerant circulates and having a second compressor, a second condenser, a second expansion mechanism, and a second evaporator, the second freezing cycle configured to cool a deep freezing compartment, a deep freezing compartment sensor, and a controller configured to operate the first freezing cycle and the second freezing cycle independently or simultaneously, thereby more efficiently cooling the freezing and refrigerating compartments and the deep freezing compartment.

A method for controlling an operation of a refrigeration appliance comprises controlling a first cooling routine for a first compartment via a flow of a thermal exchange media to a first evaporator. The method further comprises controlling a heating routine in response to a setpoint temperature being greater than the temperature of the first compartment. The heating routine comprises activating a heating element and a fan in the first compartment over a first interval and deactivating the heating element and the fan over a second interval. The heating routine continues by activating the first interval and the second interval over alternating time periods. In response to the temperature of the first compartment being greater than or equal to a target temperature associated with the setpoint, the method may control the operation of the appliance by returning to the cooling routine.

A method of controlling a storage apparatus having a plurality of lockable storage compartments includes: obtaining storage compartment temperature information, SCTI, for at least some of the storage compartments; obtaining order information associated with a likelihood of at least one order of items being placed for storage in the storage apparatus, the order information including order delivery information, ODI, indicative of a predicted delivery time for the order and order temperature information, OTI, indicative of a required storage temperature for at least some of the items associated with the order; determining a storage compartment temperature schedule, SCTS, in dependence on the order information, the SCTS indicative of a temperature control schedule for the at least some of the storage compartments and is determined to maximally utilize a predetermined storage capacity of the storage apparatus; and controlling the temperature of at least some of the storage compartments according to the SCTS.

A thermally insulated vessel contains a thermal insulation barrier defining an upper compartment above the barrier and a lower compartment below the barrier. The compartments are interconnected by a passage to allow pressure equalization. High temperature superconductor is mounted within the lower compartment for immersion in the liquid cryogen. A cryogenic refrigerator has a cold head thermally coupled to the high temperature superconductor for maintaining the high temperature superconductor below a superconductive transition temperature. A temperature controller maintains a temperature of the liquid cryogen in the upper compartment at a temperature of at least a boiling point of the liquid cryogen at atmospheric pressure when the lower compartment and at least a portion of the upper compartment are filled with the liquid cryogen.

An enclosed unit for thawing a food product is provided. The unit includes a food storage compartment and auxiliary compartment. The auxiliary compartment receives air flow from the food storage compartment and directs air across an evaporator and a heating element. A controller controls operation of the evaporator and the heating element to control the temperature around one of several nominal temperature levels associated with a recipe to thaw frozen food items disposed within the food storage compartment in a controlled manner, which is faster than placing the food within an initially refrigerated compartment for thawing.
