A portable refrigerator includes a main housing, a refrigerator cover, a cooling mechanism, a rechargeable battery pack and a control unit. The cooling mechanism includes heat exchanging tubes, a compressor, an evaporator and a condenser connected to the evaporator and the compressor. The rechargeable battery pack is detachably attached on a power compartment of the main housing. The control unit is supported in the main housing and electrically connected to the rechargeable battery pack and the cooling mechanism for centrally controlling an operation of the cooling mechanism. A predetermined amount of refrigerant is arranged to controllably pass through the heat exchanging tubes, the condenser, the evaporator and the compressor for extracting heat from the accommodating cavity.

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.

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.

The present disclosure relates to A support structure for a cryogenic system, comprising a first compartment, a second compartment, and a third compartment, wherein the first compartment, the second compartment, and the third compartment are vertically stacked in this order, wherein the first compartment is configured to accommodate a cryostat, wherein the second compartment is configured to provide access to a top portion of the cryostat for performing measurements and/or tests on an object inside the cryostat, and wherein the third compartment is configured to accommodate electronics for controlling at least the cryostat.

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.

Disclosed is a gas detector system for a refrigerated interior volume of a transportation refrigeration unit (TRU), the system having: a gas detector that defines an enclosure, the enclosure defines a chamber therein, the cover including a chamber opening, and an infrared (IR) sensor within the chamber; and a heater adjacent to or within the enclosure, the heater configured to reduce moisture within the chamber and/or prevent moisture from accumulating from within the chamber during a refrigeration cycle.

A cooling system is configured for arranging a cooling machine and a heat exchanger, for example, inside and outside a heat insulation box. A cooling unit for discharging cooled air by heat exchange using a refrigerant and a heat exchange unit for returning the refrigerant to a coolable condition are connected by a connection portion connecting the upper portions to form an integrated cooling device. The connection portion is arranged so as to straddle an end of a sidewall of the heat insulation box, the cooling unit is arranged inside the heat insulation box, and the heat exchange unit is arranged outside the heat insulation box. During storage or movement by a delivery vehicle, the cooling device is mounted on the heat insulation box. When carrying with hand, only the heat insulation box from which the cooling device is removed can be carried.

A transport refrigeration system includes a prime mover configured to power a refrigeration unit and a first fuel tank fluidly connected to prime mover through a first fuel line. The first fuel tank is configured to supply fuel to an inlet of prime mover from an outlet of first fuel tank through first fuel line. The transport refrigeration system also includes a first fuel flow sensor being an in-line flow meter and configured to measure a first fuel quantity exiting first fuel tank, a second fuel flow sensor being an in-line flow meter and configured to measure a second fuel quantity entering prime mover, a controller configured to compare second fuel quantity to first fuel quantity, and an alarm configured to activate when second fuel quantity is not equal to first fuel quantity.

Methods and systems for power management are provided. Aspects include receiving, by a controller, load data associated with two or more refrigeration systems, wherein the two or more refrigeration systems comprise at least a first refrigeration system and a second refrigeration system, determining, by the controller, an available power capacity for the first refrigeration system and the second refrigeration system, operating, by the controller, the first refrigeration system and the second refrigeration system in a plurality of modes based at least in part on the load data and the available power capacity, wherein the plurality of modes comprise an unloaded mode and a plurality of loaded modes.

In one aspect, a pump-motor assembly is provided outside of and adjacent to a storage container that stores a back-up energy storage unit. The pump-motor assembly includes a pump-motor that maintains a minimum pressure of a liquid coolant in a liquid coolant system that cools the back-up energy storage unit, and a housing that is completely enclosed, the housing containing the pump-motor, and having a removable access panel on one side thereof the enclosed structure, and an opening on another side thereof to the storage container.
