A modular shipping system includes a bulk shipping space; and a base to support a pair of stackable cryogenic shipping subunits positioned in the bulk shipping space during long distance shipment, each subunit having a plurality of feet on a subunit bottom adapted to rest above a plurality of corresponding foot receptacles on a subunit lid, each subunit having its own cryogen connection source to maintain temperature during transit.

A control method for controlling a refrigerator includes a first step for driving a compressor for compressing a refrigerant and a fan for moving air, a second step for driving the compressor and stopping the fan, a third step for stopping the compressor and driving the fan, and a fourth step for stopping the compressor and the fan.

A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

An entrance refrigerator includes a condensation removal device supplying heat dissipation air generated from a cold air supply module to an outer gasket or an inner gasket to prevent condensation formation on surfaces of the outer gasket and the inner gasket or an outer circumferential surface of a cabinet.

A refrigerator can include a storage compartment having a storage space and an opening; at least one door coupled to the storage compartment to open and close a part of the storage compartment; a compressor configured to provide the storage compartment with freezing capacity or cooling capacity; a processor configured to control driving of the compressor; and a memory operably connected to the processor and configured to store code to cause the processor to in response to recognizing placement of an item in the storage space, determine whether the item is an overload item to generate a determination result; and control the driving of the compressor to adjust a temperature of the storage space based on the determination result.

A method of controlling a refrigerator includes starting a first cooling cycle to cool a first storage compartment by operating a compressor and a first fan, determining whether a start condition of a second cooling cycle to cool a second storage compartment is satisfied, operating a second fan for the second storage compartment when the start condition of the second cooling cycle is satisfied, determining whether an output change condition of the second fan is satisfied while the second fan operates, and changing a speed of the second fan when the output change condition of the second fan is satisfied.

Method and system for maintaining temperature-sensitive materials within a target temperature range for an extended time. In one embodiment, the system keeps materials within a temperature range of +2 C. to +8 C. and includes an insulated container, a product box, ice packs, and organic phase-change material (PCM) packs. The ice packs are preconditioned to a very low temperature, such as 20 C. The organic PCM packs do not require preconditioning and may be kept at room temperature. In use, the frozen ice packs and the warm organic PCM packs may be loaded into the insulated container, together with a payload in the product box. Preferably, the frozen ice packs are sandwiched between a pair of organic PCM packs on each face of the product box. The masses of ice and organic PCM are selected so that, upon thermal equilibration, the ice and organic PCM are within the target temperature range.

A packaged food product processing machine. The machine comprises a food consumer interface configured to receive a food consumer selection identifying an end state of a food product, a package cooling sub-system comprising a chilled fluid bath, a gripper component configured to agitate a package containing the food product in the chilled fluid bath, and a controller configured to command the gripper to control the rate of heat transfer from the package to the chilled fluid bath based on receiving an input identifying an end state selection from the food consumer interface and based on receiving an input containing a value of the physical parameter of the food product from the gripper component.

A storage system that includes a contents container and a thermal battery, each in thermal communication with a thermal moderator that is constructed and arranged to balance the thermal energy flow between the contents container and the environment with the thermal energy flow between the contents container and the thermal battery. The thermal moderator can include a super-insulating material, a phase change material and/or a heat pipe. The storage system may help to maintain stored contents within a desired temperature range for an extended period of time, while minimizing the likelihood of damage to the contents due to an initial temperature of the thermal battery being outside of the desired temperature range.

A modular shipping system includes a bulk shipping space; and a base to support a pair of stackable cryogenic shipping subunits positioned in the bulk shipping space during long distance shipment, each subunit having a plurality of feet on a subunit bottom adapted to rest above a plurality of corresponding foot receptacles on a subunit lid, each subunit having its own cryogen connection source to maintain temperature during transit.
