Abstract:
Some embodiments of the disclosure are directed to an air/fluid filter device comprising a sheet of material initially configured in one or more planar sections, a plurality of organized air/fluid outlets arranged on the sheet and configured to allow the air/fluid to flow through the sheet, and a plurality of cyclonic compartments coupled to the sheet, each compartment comprising a cyclonic structure comprising at least one of a cone or a cylinder, including a tangential inlet, and a cyclonic outlet at the end of the cyclonic structure that is coupled to the sheet. In some embodiments, each tangential opening is in air/fluid communication with a respective incoming air/fluid side of the sheet, and each cyclonic outlet is coupled to a respective outlet of the sheet.
Abstract:
A sorbent for C0 2 reduction from indoor air from an enclosed space. In some embodiments, the sorbent comprises a solid support and an amine-based compound being supported by the support. The sorbent captures at least a portion of the C02 within the indoor air. The sorbent may be regenerated by streaming outdoor air through the sorbent to release at least a portion of the captured C0 2 . The sorbent is structured to allow indoor air to flow therein with relatively low flow resistance and relatively rapid reaction kinetics. Regeneration may be performed at relatively low outdoor air temperatures, thereby minimizing the thermal energy required for regenerating the sorbent.
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:
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.
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, a source of outdoor air, and an exhaust, wherein the scrubber is configured during a purge cycle to direct a purging air flow received from the source of outdoor 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:
Embodiments of the present disclosure include methods and systems of operating an HVAC system for an enclosed environment. In such embodiments, the HVAC system may be configured to at least one of heat and cool air and include an air circulation system configured to circulate air at least within the enclosed environment. The air within the enclosed environment may comprise at least the indoor air. The system may further include an outdoor air inlet for introducing at least a portion of outdoor air into the enclosed environment, where the outdoor air comprises air from outside the enclosed environment. The system may further include a scrubbing system having an adsorbent material to reduce presence of at least one gas contaminate in the indoor air. A controller system may be included for controlling the operation of at least one of the circulation system and the scrubbing system.
