Abstract: 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.

Abstract: Disclosed is a container for shipping agricultural commodities, the container including a generator that generates gas pressure to balance vacuum pressure that accumulates over time in the container.

Abstract: A refrigeration unit for use with a container. The refrigeration unit includes a compressor, a condenser, an expansion device and an evaporator configured to circulate a refrigerant; a condenser section housing the compressor and the condenser; an evaporator section housing the evaporator; an atmosphere control system including an air compressor configured to generate compressed air; a separator configured to receive the compressed air and output nitrogen; the air compressor located in the condenser section; the separator located in the evaporator section.

Abstract: A method and system for monitoring cargo conditions, includes at least one environmental sensor (50) to monitor at least one environmental parameter associated with the cargo (30), a controller (60) to log a plurality of readings from each of the at least one environmental sensors (50), and a sensor interface (51) to facilitate communication between the at least one environmental sensor (50) and the controller (60).

Abstract: A regenerative scrubber system is provided for removing a selected gas from an atmosphere within a closed environment. The scrubber system includes a scrubber module having a first scrubber and a second scrubber, each housing a porous mass of regenerative adsorbent material for adsorbing the selected gas, a first flow diversion device disposed upstream of the scrubber module with respect to the gaseous flow from the closed environment, a second flow diversion device disposed downstream of the scrubber with respect to the gaseous flow from the closed environment, and a single actuator operatively associated with each of the first flow diversion device and the second flow diversion device.

Abstract: A regenerative carbon dioxide removal system (38) is provided onboard the container (10) through which air from within the cargo box (12) may be circulated for removing at least a portion of the carbon dioxide present in the air. The regenerative carbon dioxide removal system (38) includes a scrubber module (40) containing a carbon dioxide absorbent material (42), and an actuator (50) for moving the scrubber module (40) to pass the carbon dioxide absorbent material (42) alternately between a first flow of air (32) to be cleaned drawn by the evaporator fan (30) from within the cargo box (12), and a second flow of air (44) drawn from an environment outside the cargo box for regenerating the carbon dioxide adsorbent material (42) by removing collected carbon dioxide from the carbon dioxide adsorbent material (42).

Abstract: A system and method for automatically providing a fresh air exchange to a cargo unit is disclosed. The system includes a single gas sensor, preferably a carbon dioxide sensor, for providing an input to a controller which derives the carbon dioxide and oxygen levels in the unit. The controller then compares such derived values to preselected levels and selectively opens or closes air flow into the cargo unit in order to bring and maintain the desired oxygen and carbon dioxide levels within the unit.
