A transportable coolroom module is provided including a base frame and a coolroom structure mounted on the base frame, wherein the coolroom structure includes a floor, a plurality of walls each extending above the floor, and a roof supported by the walls. At least one access door may be provided in at least one of the walls, and at least one removable infill panel may be provided in at least one of the other walls. The removable infill panel may be attached to the coolroom structure. The transportable coolroom module may be used as a stand-alone coolroom. The at least one removable infill panel may be selectively removed from the coolroom structure and the transportable coolroom module may be selectively interconnected with one or more other like transportable coolroom modules to create a larger combined coolroom environment.

A refrigerator gasket assembly has a first gasket section, a second gasket section and a coupler connecting the first gasket section and the second gasket section. The coupler is configured to permit the selective connection and disconnection of the first gasket section from the second gasket section. In some variations, the coupler is a two piece coupler and in other variations the coupler is a three piece coupler.

An illustrative example method of controlling use of a portable cooling container includes determining at least one characteristic of an amount of use of the cooling container. The at least one characteristic is determined by at least one of a processor at a location remote from the cooling container and a container controller of the cooling container. A relationship between the at least one characteristic and continued use of the cooling container is determined. An indication to a user of the cooling container is provided regarding continued use of the cooling container based on the determined relationship.

Method of stacking refrigerated shipping containers (10) including categorizing a plurality of refrigerated shipping containers (10) as a low temperature container (L) or a high temperature container (H), each of the refrigerated shipping containers (10) having a condenser (16). The method also includes disposing the plurality of refrigerated shipping containers (10) relative to each other based on the temperature categorization of the refrigerated shipping containers (10).

A transport climate control system is disclosed. The system includes a compressor, a motor-generator-rectifier machine, a belt drive connected to the motor-generator-rectifier machine and the compressor, at least one condenser fan, at least one evaporator fan, and a DC to DC converter. The motor-generator-rectifier machine connects to the at least one condenser fan, the at least one evaporator fan, and the DC to DC converter. The motor-generator-rectifier machine includes a motor, a low voltage generator connected to the motor, and a rectifier connected to the low voltage generator. The motor-generator-rectifier machine can provide a first low voltage DC power to the at least one condenser fan, the at least one evaporator fan, and the DC to DC converter. The DC to DC converter can convert the first low voltage DC power to a second low voltage DC power that is different from the first low voltage DC power.

A trunk cooler removably connected under a seat of a vehicle, the trunk cooler including a base cooler receptacle to store at least one item therein, a plurality of retractable legs disposed on a bottom surface of the base cooler receptacle to support the base cooler receptacle in response to moving the plurality of retractable legs from being retracted in a first vertical position to at least partially extended in a second vertical position, and a cooling system to inject cold air into an interior portion of the base cooler.

A cooling unit enabled to maintain the internal temperature for an extended period of time without an outside electrical power is described. The cooling unit uses a combination of a battery (or one or more battery backs) and one or more phase change materials (“PCM”). In addition, the cooling unit uses one or more airpaths to force cooled air over a group of PCM to maintain the PCM for the event when an external electrical power is discontinued and the power from the battery pack is also depleted. The forced air through one of more airpaths may be always used or only when the cooling unit is operated by only the battery power.

A transportation refrigeration system including: a transportation refrigeration unit comprising a motor; a power conversion unit configured convert an amplitude, a frequency and a phase of an input electrical power signal, wherein the power conversion unit comprises a first power bridge, a DC link and a second power bridge; an energy storage device configured to supply electrical power to the motor via the power conversion unit during a road mode; a first switch configured to selectively connect the first power bridge to the energy storage device or the motor; and a second switch configured to selectively connect the second power bridge to the motor or a power grid; wherein the first switch and second switch are positioned to connect the first power bridge and second power bridge to specified sources and outputs during each of the road mode and the standby mode.

A food stand system with a plan view in the shape of an incomplete circle, with a flat top surface as a countertop, and a convex customer-facing surface. The stand contains a food preparation appliance having both cooking and refrigeration components. Sensors measure the appliance interior state, and provide data to an automated controller that controls appliance operation to prepare food for consumption.
