Scrubber system with moving adsorbent bed

摘要

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).

1. A refrigerated transport container comprising:
a cargo box; a compressor and a condenser/gas cooler module isolated from the cargo box by a partition panel; an evaporator module including an evaporator heat exchanger and an associated evaporator fan disposed in air flow communication with the cargo box; a regenerative scrubber system for removing carbon dioxide from the atmosphere within the cargo box, the regenerative scrubber system comprising: a scrubber module containing a carbon dioxide adsorbent material; and an actuator for moving the scrubber module to pass the carbon dioxide adsorbent material alternately between a first flow of air to be cleaned drawn by the evaporator fan from within the cargo box from which carbon dioxide is removed and a second flow of air from an environment outside the cargo box for regenerating the carbon dioxide adsorbent material by removing collected carbon dioxide from the carbon dioxide adsorbent material.
