A method is provided for operating a controlled atmosphere (CA) system to regulate the atmosphere in a cargo storage space. The CA system comprises a gas exchange module operable to vary the level of a component gas in the cargo storage space, a control module to control operation of the gas exchange module, and at least one of an oxygen sensor and a carbon dioxide sensor, each being operable to measure a parameter indicative of a level of oxygen or carbon dioxide respectively in the cargo storage space. The method comprises: the control module determining a respiration parameter value indicative of the rate of change of oxygen level and/or the rate of change of carbon dioxide level in the cargo storage space due to respiration of goods in the cargo storage space; and the control module controlling operation of the gas exchange module based on the determined respiration parameter value to target an oxygen level setpoint and/or a carbon dioxide level setpoint.

A galley cart has a rear wall with an inlet port and an outlet port. A first divider has a first edge, wherein a first distance is defined between the first edge and a front wall. A second divider has a second edge, wherein a second distance is defined between the second edge and the front wall. The second distance is less than the first distance for control of the flow of cooling air.

A tractor trailer system includes a tractor and a trailer. The tractor includes a hotel device and an Auxiliary Power Unit (APU) configured to provide electrical power to the hotel device.

The portable enclosure includes capability of cellular and GPS location beacon identification, comprehensive internal status and operation monitoring, and wireless communication capability of the device status, temperature and humidity parameters, and location using BLUE TOOTH, WIFI and/or cellular technology. The system is powered by an onboard rechargeable battery, external DC power, or external AC power.

An electrical system can include a diagnostic device that generates a first test signal at a first time. The electrical system can also include at least one energy transfer link coupled to the diagnostic device, where the first test signal flows through the at least one energy transfer link at the first time. The electrical system can further include a portable electrical load coupled to the at least one energy transfer link. The electrical system can also include a monitoring device coupled to the at least one energy transfer link, where the monitoring device is disposed between the diagnostic device and the portable electrical load. The first monitoring device can receive the first test signal, where the monitoring device executes, in response to the first test signal, a test procedure on the portable electrical load. The portable electrical load is portable relative to the diagnostic device.

An apparatus for maintaining a constant temperature of a beverage for the duration of its consumption. The apparatus comprising a container enclosing a volume. The container having a container floor facing the volume, a release valve, and a container roof positioned opposite the container floor. The container roof having a container roof inlet that penetrates the container roof. A trough coupled to the container roof inlet. The trough has at least one beverage mount for holding the beverage. A trough outlet and a water pump is coupled to the trough for transferring a fluid through the trough and the trough outlet.

A method of monitoring a health of a transportation refrigeration unit including: receiving at least one of an alarm of one or more components of the transportation refrigeration unit, test data on the one or more components of the transportation refrigeration unit, historical trip data of the transportation refrigeration unit, or service data of the transportation refrigeration unit; receiving reefer parameters of the transportation refrigeration unit; determining a health score of the transportation refrigeration unit based on at least the reefer parameters; and determining a maintenance action for transportation refrigeration unit based on the health score and at least one of the alarm, the test data, the historical trip data, or the service data.

A transport refrigeration system (26) includes a transport refrigeration unit (44), an energy storage device (46), a supply refrigerant tube (108), a return refrigerant tube (110) and at least one electrical pathway (98). The transport refrigeration unit is adapted to cool a container. The energy storage device is adapted to provide electrical energy for operating the transport refrigeration unit. The supply refrigerant tube flows a refrigerant from the transport refrigeration unit to the energy storage device, and the return refrigerant tube flows the refrigerant from the energy storage device back to the transport refrigeration unit to cool the battery in the energy storage device (46). The electrical pathway extends between the transport refrigeration unit and the energy storage device, and supplies at least electrical energy to the transport refrigeration unit.

A container energy storage system is provided in this disclosure. The system includes a container and a plurality of functional assemblies. The container includes a container frame and a bottom plate. The container frame is formed a plurality of openings and a hollow main body. The bottom plate is disposed at the bottom of the container frame and is fixedly connected to the container frame. The functional assemblies are disposed in the hollow main body and located above the bottom plate.

In an example, a transformable cargo container for use with ground and air transportation vehicles is disclosed. The cargo container includes a main container body defining a storage chamber therein and including at least one inlet. The cargo container also includes a transformable assembly coupled to the main container body and positioned at an exterior of the main container body. The transformable assembly includes one or more supplemental containers and one or more supply ducts, at least one of the supplemental container(s) being configured to house refrigeration equipment. The transformable assembly is movable between an aircraft configuration and a ground configuration.
