Abstract: A method and apparatus are disclosed for controlling a concentration of carbon dioxide in a gaseous atmosphere within a closed environment of a refrigerated transport container to maintain the concentration of carbon dioxide therein at a desired level. A carbon dioxide scrubber apparatus operates alternately in an adsorption mode and a regeneration mode. When a perishable produce is stowed in the closed environment, for example in a cargo box of a refrigerated transport container, the concentration of carbon dioxide may be maintain at a desired level to retard ripening of the perishable produce.

Abstract: Embodiments of systems, apparatus, and/or methods can provide conditioning building terminal fan coil units (e.g., ceiling mounted) configured with a filter to remove particles, selected gases such as formaldehyde, or provide biocidal capability while retaining sufficient FCU airflow. Embodiments of systems, apparatus, and/or methods according to the application can provide a transport refrigeration system and/or components to regulate ethylene gas levels in airflow, for example, of air conditioned by the transport refrigeration system. In one embodiment, a portion of the air conditioned by the transport refrigeration system can pass through an ethylene filter.
