Abstract:
An air filtration system comprising a plurality of sections configured to receive an incoming airstream is disclosed. In some embodiments, each section of the plurality of sections includes a first airstream receiving side (ASRS) and a second air stream exhaust side (ASES), and a plurality of cells each comprising a cyclonic cavity having a tangential inlet arranged to receive a portion of the airstream via the ASRS, and an axial outlet arranged to exhaust the portion of the airstream to the ASES. Each section is further configured with a cover that can be opened and closed, such that the closing of one or more respective covers of respective sections forces the airstream to flow through remaining sections having open covers as well as their respective cells, at a velocity greater than when such one or more respective covers are open.
Abstract:
An air filter comprising a housing, a plurality of cyclonic-element arrays and a plurality of individual airflow paths is disclosed herein. The housing includes a first side configured to be arranged or otherwise exposed to an upstream side of a first airflow, and a second side configured to be arranged or otherwise exposed to a downstream side of the first airflow. In some embodiments, the plurality of cyclonic-element arrays may be organized in a parallel or approximately parallel arrangement within and/or supported by the housing. Further, the plurality of individual airflow paths may correspond to the plurality individual of cyclone elements in each array life.

The first and/or second permeable membrane are configured for affixation to respective ends of the walls through a process of melting and solidification of the wall material such that wall material bonds with the membrane material.
Abstract:
Some embodiments of the present disclosure present closed-loop heating, temperature-swing adsorption regenerative scrubbing systems and methods. In some embodiments, such embodiments include providing a scrubbing system including a sorbent material, a plurality of dampers for controlling airflow over and/or through the sorbent according to an absorption mode, a closed-loop heating mode and a flushing mode, first controlling of the plurality of dampers so as to establish flowing an indoor airflow over and/or through the adsorbent during the adsorption mode, second controlling of the plurality of dampers so as to establish a closed loop airflow during the closed-loop heating mode, and third controlling of the plurality of dampers so as to establish a purging airflow during the flushing mode.
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.
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:
Method, systems, and devices for determining instantaneous heat exchange between an airflow and a heat exchange element of an HVAC system are disclosed. In some embodiments, methods and systems include receiving or otherwise obtaining airflow data, temperature and humidity data. The airflow data may be used to calculate the volumetric airflow rate, and the temperature and humidity data may be processed with enthalpy data to determine the change in enthalpy ( Δh ) of the airflow after encountering a heat exchange element. The instantaneous rate of heat exchange ( E ) between the airflow and the heat exchange element may then be determined from the volumetric airflow rate and change in enthalpy.
Abstract:
Methods, systems, and devices for an automotive vehicle air cleaning system are provided which may be configured to operate in at least an adsorption mode and an in-situ regeneration mode are disclosed. The system includes at least one type of sorbent material configured to remove CO 2 from a cabin of an automotive vehicle according to a repeated adsorption- desorption swing cycle, a first inlet configured to supply a first airfiow of air from the cabin to the system during an adsorption mode, and a first outlet configured to return the first airflow after passing over and/or through the sorbent material during the adsorption mode. The system includes a second inlet configured to supply a second airflow of outside air to the system during a regeneration mode, a second outlet to return the second airflow after passing over and/or through the sorbent material during the regeneration mode.
