A storage and dispensing system for storing and dispensing temperature sensitive items is provided. The system includes a storage chamber, a dispensing chamber, an electro-mechanical module, and a cooling system. The storage chamber has walls defining plural compartments formed integrally therein for storing the temperature sensitive items at an ultra-low temperature. Each compartment is formed as a cylindrical sector with an inclined bottom surface. The plural compartments are arranged circumferentially around a vertical axis and stacked together in one or more rows, thereby an individual temperature sensitive item is slidable out of a respective compartment to the dispensing chamber by gravitational force. The electro-mechanical module is configured to rotate the storage chamber about the vertical axis. The storage chamber does not include any mechanical or electrical components inside, which avoids the need for devices that can tolerate an extremely low temperature environment.

A dual redundant cooling system for a container is provided. The dual redundant cooling system includes a first cooling unit and a second cooling unit. The first cooling unit is positioned in a first cabinet attached to the container. The first cooling unit includes a first controller operating a first cooling loop to cool an interior of the container. The second cooling unit is positioned in a second cabinet attached to the container and adjacent the first cabinet. The second cooling unit includes a second controller operating a second cooling loop to cool the interior of the container. The first cooling unit and the first cooling loop are separate from the second cooling unit and the second cooling loop. The first controller and the second controller communicate a switch signal between each other so that either the first cooling unit is a primary cooling unit operating the first cooling loop or the second cooling unit is the primary cooling unit operating the second cooling loop. The switch signal switching the primary cooling unit.

A storage system for a house entrance includes an entrance refrigerator, a storage placed at a rear of the entrance refrigerator, and a blocking plate covering a gap formed between the entrance refrigerator and the storage. An intake hole is provided at a lower portion of the blocking plate and a discharge hole is provided at an upper portion of the blocking plate.

A refrigerator and method utilize a door-mounted icemaking system including an icemaking mold, an ice storage bin and a cold wall evaporator disposed proximate the ice storage bin along an interior wall of the door to provide cooling proximate the ice storage bin. In some instances, the cold wall evaporator may be in addition to an icemaking evaporator that provides direct cooling of the icemaking mold, and furthermore, in some instances, the cold wall and icemaking evaporators may be separately controllable to optimize cooling within the door-mounted icemaking system. In addition, in some instances, a hot wall condenser may be used in a door-mounted icemaking system to dissipate heat generated by a refrigeration circuit through an exterior wall of a door. Further, in some instances a reversible refrigeration circuit may be used in connection with an icemaking evaporator to assist in ejecting ice from an icemaking mold.

A merchandise display for displaying, refrigerating, and dispensing containers of a frozen product along an aisle may include a) a lower shelf and b) an upper shelf disposed above the lower shelf along a longitudinal axis of the merchandise display, c) a support portion operably coupled to the lower shelf and the upper shelf to form an assembly, radial extent of the assembly from the longitudinal axis forming a radial envelope of the merchandise display, and d) at least one refrigerating appliance configured to keep the frozen product frozen, disposed on the lower shelf or the upper shelf, and including a door configured to be moved between opened and closed positions to expose and close, respectively, the refrigerating chamber remaining within the radial envelope of the merchandise display.

This refrigeration device is provided with: an evaporator configuring a refrigeration circuit; a cascade condenser configuring the refrigeration circuit; and a thermal insulation board arranged between the evaporator and the cascade condenser.

Exemplary embodiments provide a refrigeration system having an interior space cooled by a plurality of cooling. Each cooling unit is capable of operating either synchronously when in communication with a control panel or under independent operation. Each cooling unit is modularly and replaceable without the use of tools by means of a quick connect system. The cooling units use a heat exchanger cooled by chilled water and make use of an electronic super heat control and electronic expansion valve to regulate the flow of refrigerant for improved efficiency.
