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.
Abstract:
A system for conditioning air in a building including a fan-coil unit arranged adjacent to or within an indoor space within the building and additionally configured to at least one of heat and cool the air of the indoor space, and a scrubber arranged adjacent to or within the indoor space, the scrubber configured during a scrub cycle for scrubbing of indoor air from the indoor space. The scrubber includes one or more adsorbent materials arranged therein to adsorb at least one predetermined gas from the indoor air during the scrub cycle, and an exhaust, wherein the scrubber is configured during a purge cycle to direct a purging air over and/or through the adsorbent materials to purge at least a portion of the at least one predetermined gas adsorbed by the adsorbent materials during the scrub cycle from the adsorbent materials and thereafter exhausting the flow via the exhaust.
Abstract:
Some embodiments of the disclosure are directed to an air treatment system, and corresponding methodology, for at least partially removing at least one gaseous contaminant contained in indoor air of a room structured for human occupants. In some embodiments, the system may comprise an air treatment assembly having an indoor air inlet configured to receive indoor airflow directly from a room, a regenerable adsorbent material configured to adsorb at least one gaseous contaminant contained in the indoor airflow, at least one airflow element for directing the indoor airflow to flow through the air treatment assembly, an indoor air outlet for expelling the indoor air, from the air treatment assembly back into the room, a purge air inlet configured to receive and direct purge air from the room over and/or through the adsorbent material for removal of at least a portion of the at least one gaseous contaminant, and a purge air outlet for expelling the purge air out of the air treatment assembly.
Abstract:
A regenerable air scrubbing system comprises of an air flow assembly with replaceable cartridges arranged in a parallel orientation and designed for easy insertion and removal of the cartridges. The cartridge design enhances the contact area, reduces the pressure drop, and readily allows the design of similar assemblies with different airflow throughputs using the same cartridge, while facilitating easy replacement of the sorbent in the field. The cartridge can be partitioned into smaller compartments, improving the mechanical properties of the cartridge and the uniformity of the sorbent distribution.
Abstract:
Embodiments of the present disclosure include methods and systems of circulating air in an enclosed environment. In such embodiments, the system may comprise an air handling unit (AHU), the AHU including an indoor air inlet to receive an indoor airflow from the enclosed environment and an indoor air outlet to expel the indoor airflow, a conditioning element arranged between the inlet and the outlet configured to at least heat or cool the indoor airflow as it flows thereover, one or more fan units arranged between the inlet and the outlet configured to provide velocity to the indoor airflow, and an air treatment assembly (ATA) arranged within or proximate the AHU, the ATA including an air inlet configured to receive a portion of the indoor airflow received by the AHU indoor air inlet.
Abstract:
Embodiments of the present disclosure are directed to systems and methods for removing formaldehyde from indoor air. Some embodiments include flowing an indoor airflow over and/or through a solid supported amine filtering medium, such that, at least a portion of formaldehyde entrained in the indoor airflow is removed therefrom. Some other embodiments include systems having one or more fans for providing velocity to one and/or another airflows (e.g., airflows to/from a formaldehyde filter).
Abstract:
Some embodiments of the disclosure correspond to, for example, a method for controlling a scrubber containing an adsorbent. The scrubber may be configured to cycle between scrubbing at least one pollutant/gas from a stream of gases with the pollutant/gas being adsorbed onto the adsorbent, and regenerating at least some of the adsorbent and thereby purging at least some of the one pollutant and/or first gas from the adsorbent via a regeneration gas flow. The method may include flowing a stream of gases through the scrubber, the scrubber including the adsorbent and adsorbing at least some of the one pollutant/gas from the stream of gases onto the adsorbent during an adsorption phase over a first time period. The method may also include purging at least a portion of the one pollutant/gas from the adsorbent during a regeneration phase over a second time period with a regeneration gas flow, and cycling therebetween.
Abstract:
In some embodiments, there is provided a scrubber system for cleaning return air in an HVAC unit, where the scrubber system attaches directly to an inlet of the return-air side of the HVAC unit, for example, by the mating of a flange on the system with a matching flange on the HVAC unit. The bolt-on scrubber system may comprise one or more sorbent materials, a fan for circulating return air through the sorbent, a damper-controlled inlet and a damper-controlled outlet to the attached return air side of the HVAC unit. Further, an additional air flow channel and a damper may be included in the system to control the flow of outside air into the HVAC unit. In some embodiments, the sorbents may be contained in removable inserts.
