1. A building indoor air circulation system comprising:
- an HVAC system configured to circulate indoor air and to heat or cool the circulated indoor air;
a gas scrubbing system (GSS) including an adsorbent configured to;
operate in an adsorption mode wherein the adsorbent adsorbs at least one gas constituent contained in the indoor air, andoperating in a regeneration modepurging lines in communication with the GSS and configured to flow a purge substance over and/or through the adsorbent, wherein;
the adsorbent is heated either directly or via the purge substance so as to release at least a portion of the at least one gas constituent adsorbed by the adsorbent into the purge substance; and
the purge substance is exhausted upon the completion of the regeneration mode;
a sensor configured to provide signals indicative of a measurement of an amount of the at least one gas constituent contained in the circulated indoor air;
andductwork configured to direct circulated indoor air to and from at least the HVAC system;
wherein;
the HVAC system and ductwork is configured to divert at least a portion of the circulated indoor air to the GSS during the adsorption mode for adsorbing the at least one gas constituent from the circulated indoor air at least during a period of time that the sensor signals indicate that the measurement of the at least one gas constituent in the indoor air is greater than a threshold.

Abstract
Systems and methods for circulating air in an enclosed environment are disclosed. In some embodiments, the system includes an inlet to receive air from outside of the enclosed environment and an air handling unit coupled to the inlet and also configured to receive circulated air from the enclosed environment. The air handling unit can be configured to affect a temperature of at least one of the received outside air and the received circulated air. Based on the received outside air and the received circulated air, the air handling unit can be further configured to generate air for supplying to the enclosed environment.
