Modular, high-throughput air treatment system
First Claim
1. An air treatment system for removing contaminants from indoor air, the system comprising:
- a source of indoor air providing an indoor airflow containing one or more contaminates;
a source of purging air, different from the source of indoor air, configured to provide a purging airflow to release contaminants adsorbed by an adsorbent;
one or more air treatment modules each having one or more first air ports, one or more second air ports, and a plurality of inserts each including an adsorbent material;
controls configured to cause the system to operate in at least three operational modes including;
an active adsorption mode in which the adsorbent material of the plurality of inserts adsorb one or more contaminants from the indoor airflow, a regeneration mode for releasing contaminants from the adsorbent material of the plurality of inserts when exposed to the purging airflow, anda disconnect mode where substantially no air flows through the one or more modules, one or more valves arranged and configured to direct, during one or another operational mode, at least one of the indoor airflow and the purging air flow to flow to and from the one or more treatment modules via the first air ports and the second air ports; and
wherein;
during the active adsorption mode, one of either the first air ports or the second ports is configured to receive the indoor air flow and the remaining one of the first air ports or the second air ports not receiving the indoor airflow is configured to expel the indoor airflow such that the indoor airflow flows over and/or through adsorbent material of the plurality of inserts, andduring the regeneration mode, one of the first air ports or the second air ports is configured to receive the purging airflow and the remaining one of the first air ports or the second air ports is configured to expel the purging airflow such that the purging airflow flows over and/or through the adsorbent material of the plurality of inserts; and
wherein the one or more air treatment modules comprise a plurality of air treatment modules adjacently affixed to one another, and wherein the system further includes a common inlet plenum and a common outlet plenum arranged to communication with the first ports and the second ports, and the plurality of inserts of the plurality of adjacent air treatment modules form a plurality of substantially parallel air flow paths between the one or more first air ports and the one or more second air ports.

Abstract
Air treatment modules, systems and methods for removing contaminants from indoor air are provided. Device embodiments may include one or more air inlets, one or more air outlets and a plurality of inserts which each include at least one adsorbent material. The inserts may be arranged separate from each other to form a plurality of substantially parallel air flow paths between the one or more air inlets and one or more air outlets. The adsorbent material may be arranged for regeneration within the air treatment module using thermal swing desorption and/or pressure swing desorption. Related systems, methods and articles of manufacture are also described.

11. A method for removing contaminants from indoor air, comprising:
-
providing a system comprising; a source of indoor air providing an indoor airflow containing one or more contaminates; a source of purging air, different from the source of indoor air, configured to provide a purging airflow to release contaminants adsorbed by an adsorbent; one or more air treatment modules each having one or more first air ports, one or more second air ports, and a plurality of inserts each including an adsorbent material; controls configured to cause the system to operate in at least three operational modes including; an active adsorption mode in which the adsorbent material of the plurality of inserts adsorb one or more contaminants from the indoor airflow, a regeneration mode for releasing contaminants from the adsorbent material of the plurality of inserts when exposed to the purging airflow, and a disconnect mode where substantially no air flows through the one or more modules; and one or more valves arranged and configured to direct, during one or another operational mode, at least one of the indoor airflow and the purging air flow to flow to and from the one or more treatment modules via the first air ports and the second air ports; and upon selection of the active adsorption mode, directing the indoor airflow to one of either the first air ports or the second ports of each module; flowing the indoor airflow over and/or through the adsorption material of the inserts so as to adsorb contaminants thereon, the resulting airflow comprising a scrubbed indoor airflow; directing the scrubbed indoor airflow to the remaining one of the first air ports or the second air ports not receiving the indoor airflow to expel such airflow from each module; upon selection of the regeneration mode, directing the purging airflow to one of the first air ports or the second air ports of each module; flowing the purging airflow over and/or through the adsorption material of the inserts so as to release adsorbed contaminants, the resulting purging airflow containing the released contaminants being thereafter directed to the remaining one of the first air ports or the second air ports to expel such airflow from each module; and upon selection of the disconnect mode, ceasing the flow of an airflow through the one or more modules; and wherein the one or more air treatment modules comprise a plurality of air treatment modules adjacently affixed to one another, and wherein the system further includes a common inlet plenum and a common outlet plenum arranged to communication with the first ports and the second ports, and the plurality of inserts of the plurality of adjacent air treatment modules form a plurality of substantially parallel air flow paths between the one or more first air ports and the one or more second air ports.
