Left and right edge portions of an external casing of a container refrigeration apparatus each include a column member that is continuous from the upper end to the lower end of a casing. Left and right edge portions of an internal casing each include a side plate that is continuous from the upper end to the lower end of the casing. The column members of the external casing and the associated side plates of the internal casing are fixed together, thereby increasing the strength of the casing including the external casing and the internal casing.

A transportation refrigeration unit is provided. The transportation refrigeration unit comprising: a compressor configured to compress a refrigerant; a compressor motor configured to drive the compressor; an evaporator heat exchanger operatively coupled to the compressor; an energy storage device for providing power to the compressor motor; and an evaporator fan configured to provide return airflow from a return air intake and flow the return airflow over the evaporator heat exchanger, wherein the return airflow thermodynamically adjusts a temperature of the energy storage device.

Provided is a refrigerator. The refrigerator includes: a cabinet forming a storage chamber therein and including a cooling module mounting portion, a cabinet sealing portion formed on an outer surface of the cooling module mounting portion; a cooling module detachably mounted to the cooling module mounting portion and including an evaporator, a condenser, and a compressor, wherein the cooling module includes a module housing, and the module housing includes a module sealing portion facing the cabinet sealing portion, and the module sealing portion includes a module inclination portion positioned at an inclination with respect to a direction in which the cooling module is insertable into the cabinet to be mounted to the cabinet; and a sealing member positioned between the cabinet sealing portion and the module sealing portion.

An automated order fulfillment system is disclosed having different temperature zones and robots and containers capable of and/or configured to work in these different temperature zones.

The apparatus is for use with an electron microscope, a sample, a source of high pressure gas and a vacuum pump system. The apparatus includes a holder part a body part and a Joule-Thomson refrigerator. The holder part is adapted to receive the sample and adapted to present the sample to the microscope for inspection in use. The body part defines a cavity, the cavity being evacuated by the vacuum pump system for use. The refrigerator is disposed within the cavity and thermally-coupled to the holder part, the refrigerator being coupled in use to the source of high pressure gas to maintain the sample at about a predetermined temperature.

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 method and system for converting a conventional cooler to a refrigerator. A heat transfer module is disposed within the cooler for cooling the contents therein, while an external cooling module includes refrigerant in a closed loop configuration that stays outside of the cooler. The heat transfer module includes a closed loop chilling fluid that extends outside the cooler through a drain port to perform a heat exchange with the refrigerant loop.

In various examples of the disclosure, a climate-controlled container configured to be transported by a robot is provided, the climate-controlled container comprising a plurality of walls defining a compartment to store goods, a lid configured to seal the compartment, at least one climate-control unit configured to control a climate inside the compartment, a controller configured to control the at least one climate-control unit to maintain a temperature of the compartment within a range of temperature values, and a power interface configured to receive electrical power from at least one shelving unit to which the climate-controlled container is coupled.

A refrigerated logistics box, consisting of a box, is configured with a plurality of thermal insulating layers and temperature equalization plates. Cooling liquid is caused to enter the interior of the box to maintain a cold temperature therein for a period of time, or a refrigeration device provides the box with a cold source, which continuously transmits cold to the interior of the box, and cooling liquid inside the box is caused to flow back into the refrigeration device to repeat the cooling process. Such a cyclic cooling process maintains the temperature set for the interior of the box.
