A hatch device comprised by a main support body (3), a flow guide piece (24) and an optional plug (30), which allows for minimum modifications in the service hatch cover's (2) structure during installation, as shown in FIG. 7/9.

A system includes a rigid container configured to receive a dry cargo and a flexible container configured to receive a bulk liquid. The flexible container is configured to be disposed within the rigid container when the flexible container contains the bulk liquid. The flexible container includes a set of container portions and a set of restriction portions. Each container portion has a first cross-sectional area and each restriction portion defines a second cross-sectional area less than the first cross-sectional area. Each restriction portion is disposed between a pair of adjacent container portions and is configured to restrict a flow of the bulk liquid therebetween. The restricting of the flow of the bulk liquid between the container portions is configured to limit load shifting associated with the flexible container when disposed in the rigid container.

A method of operating an atmosphere control system to control an atmosphere in a refrigerated container includes operating the atmosphere control system in a start up phase to control an oxygen level in the container; ending the start up phase; and operating the atmosphere control system in a control phase to control the oxygen level and a carbon dioxide level in the container.

Temperature controlled cargo containers may include thermal masses conditioned to temperatures above and/or below a target temperature. Example thermal masses may include plates including phase change materials, such as eutectic materials. One or more fans and flapper valves may be selectively operated to circulate air in the cargo container across one or more of the thermal masses to maintain the temperature within the cargo container within a prescribed temperature band. Some example temperature controlled cargo containers may include refrigeration units and/or heaters for regenerating the thermal masses when receiving power from an external power source and/or may include one or more rechargeable batteries for providing power during transport or storage independent of external power sources.

A shipping container is provided and includes a structural frame defining an interior, a transport refrigeration unit (TRU) and a control system. The TRU includes an inlet through which air is drawn from a lower region of the interior, a refrigeration unit configured to cool the air drawn from the lower region of the interior through the inlet and an outlet through which air cooled by the refrigeration unit is exhausted toward an upper region of the interior. The control system is configured to control an exhaustion of the air cooled by the refrigeration unit toward the upper region of the interior to maintain a predefined environmental condition within the interior.

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 refrigerated transport system (20) comprises a body (22) enclosing a refrigerated compartment (69). A refrigeration system (30) comprises: a vapor compression loop (31) having a first heat exchanger (38) positioned to reject heat to an external environment in a cooling mode. A heat transfer loop (32) has a second heat exchanger (58) positioned to absorb heat from the refrigerated compartment in the cooling mode. An inter-loop heat exchanger (44) has a first leg (42) along the vapor compression loop and a second leg (43) along the heat transfer loop in heat exchange relation with the first leg.

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 moveable between an aircraft configuration and a ground configuration. Based on the transformable assembly being in either the aircraft configuration or the ground configuration, the refrigeration equipment is configured to supply coolant into the main container body via the supply duct(s) and the inlet(s).

An assembly for saturating or aerating a medium with fluid. At least one hollow cylinder having gates and vents embedded within a grain mass. A target section of grain mass is identified and the gates and vents activated to provide influent flow to the target section in both vertical and horizontal directions.

A movable storage container includes: a plurality of walls defining an enclosure for storing items; a solar power generation array affixed to an outer surface of at least one of the walls; an energy storage device configured to receive power from the solar power generation array; a switch assembly configured to: selectively receive power from a source selected from (i) the energy storage device, (ii) an auxiliary generator, and (iii) an electrical grid input, and direct the received power to a refrigeration unit; a polyphase inverter assembly connected between the energy storage device and the switch assembly, and a controller connected with the switch and configured to transmit source selection commands to the switch.
