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.

Method and system for conditioning air in an enclosed environment with distributed air circulation systems

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.

Regenerable sorbent cartridge assemblies in air scrubbers

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.

Methods and systems for a heating, ventilation, and air-conditioning (HVAC) system for an enclosed environment 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 contaminant 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.

Systems and methods for air-conditioning systems with scrubbing systems including a scrubbing bypass mode

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 (&#x394;h) 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.
