A refrigerator comprises a fresh food compartment and a freezer compartment and one or more power consuming features / functions including a refrigeration system for cooling the fresh food compartment and the freezer compartment. A controller is operatively connected to the one or more power consuming features / functions. The controller is configured to receive and process a signal indicative of current state of an associated energy supplying utility. The controller operates the refrigerator in one of plurality of operating modes, including at least a normal operating mode and an energy savings mode, in response to the received signal. The controller is configured to at least one of selectively schedule, delay, adjust and deactivate at least one of the one or more power consuming features / functions to reduce power consumption of the refrigerator in the energy savings mode.

A smart refrigerator system includes a plurality of compartments for storing food items and one or more tag readers. The smart refrigerator system may read a tag coupled to a food item using one of one or more tag readers. The smart refrigerator system may determine an identity of the food item, an associated date of the food item, and / or a compartment containing the food item. The smart refrigerator system may track item information that includes the identity of the food item, a state of the food item, and / or a compartment location of the food item. The smart refrigerator system may receive item usage information indicating when a user plans to use the food item and change a temperature of the food item. The smart refrigerator system may also generate a notification regarding freshness and / or a spoilage level of the food item and present it to the user.

An outer surface of a cold-storage container (or a refrigerant tube) is provided with a plurality of protrusion portions or recess portions. A cooling air passage, in which air flows to cool a space to be cooled in a cold storage time and in a cold release time of the cold storage material, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container bonded to the refrigerant tube. The refrigerant tubes and the cold storage container form therebetween a cold-storage side air passage by the protrusion portions or the recess portions, such that air flows in the cold-storage side air passage separated from the cooling air passage. For example, the cold-storage side air passage is provided with a slanting space that causes condensed water or ice generated in the cold storage time to be drained along the cold-storage side air passage.

A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g. −80° C. or −135° C.) or cryogenic (e.g., about −140° C. to −196° C.) storage and retrieval system that stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are normally stored within an ultra-low temperature or cryogenic freezer compartment. The tube picking mechanism includes a tube picking chamber that is maintained at about −80° C., about −135° C. or at cryogenic temperatures in cryogenic applications. Active electrical and mechanical components are maintained in a compartment above and separate from the refrigerated, ultra-low temperature or cryogenic compartment. Thermal stratification inhibits heat transfer into the lower, ultra-low temperature or cryogenic compartment in which tube picking occurs from the upper compartment in which active electrical and mechanical components are located, and also inhibits heat transfer into the lower, ultra-low temperature or cryogenic compartment via an access door for tube storage racks.

A method of controlling temperature for forming ice within an icemaker compartment of a refrigerator is disclosed. The method includes the steps of activating at least one of the compressor and the coolant pump during an icemaking cycle to provide cooling to the icemaker compartment sufficient to make ice at a first rate, and increasing operation of at least one of the compressor and the coolant pump to provide cooling to the icemaker compartment sufficient to make ice at a second rate, which is faster than the first rate. A related refrigerator is also disclosed.

A climatic cabinet and storage cabinet that includes an upper zone, a lower zone, storage positions for storing objects in one of the upper and lower zone, and at least one temperature control unit structured and arranged to maintain a temperature in the one of the upper and lower zone different from the other of the upper and lower zone. The cabinet further includes a lock, a horizontal transport mechanism arranged at least in part in the other of the upper and lower zone to move the objects to and from the lock in a direction having a horizontal component, and a vertical transport mechanism structured and arranged to move the objects between the lower zone and the upper zone.

An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined length and to which water is supplied to make ice. The ice maker is configured to mechanically separate the ice from the tray by using pistons which are driven by being pressed by structures. This allows the ice maker to have a reduced size, and a small occupation area, thereby implementing a slim configuration of a refrigerator. Furthermore, since an installation height of the ice maker is lowered, a path for supplying cool air may be shortened. This may prevent loss of cool air being supplied to the ice making chamber. Since the ice maker has a simplified configuration and precise operation controls, the fabrication costs may be reduced, and inferiority of the ice maker due to malfunctions may be prevented.

Provided is a refrigeration appliance including a fresh food compartment for storing food items in a refrigerated environment having a target temperature above zero degrees Centigrade. A freezer compartment is disposed at an elevation vertically below the fresh food compartment for storing food items in a sub-freezing environment having a target temperature below zero degrees Centigrade. The refrigeration appliance also includes one or more of a hand-removable insulated cover, a cool air duct for introducing cooled air adjacent an ice bin, and a rearward-sloped catch pan positioned to catch dripping water in said ice maker and direct the dripping water into a drain.
