Abstract:
An air treatment module for removing vapors and/or gases from airin an inside space of a building, comprising: a plurality of chamber walls defining a chamber; an inlet in fluid communication with the chamber, the inlet for receiving an air stream from the inside space of the building; a first outlet in fluid communication with the chamber and in fluid communication with the inside space of the building; a second outlet in fluid communication with the chamber and in fluid communication with an outside space of the building; one or more valves for selectively directing the air stream between the first output and the second outlet; an air treatment matrix positioned in the chamber for receiving the air stream from the inside space of the building, the air treatment matrix adapted to adsorb vapors and/or gases from the air stream, the air treatment matrix including a plurality of matrix walls defining a plurality of air flow channels, wherein at least some of the matrix walls include a material that warms when an electrical current is conducted therethrough; and heating means for at least selectively providing electric current through at least some of the matrix walls of the air treatment matrix to heat the air stream from the inside space of the building, the heating means selectively heating the air stream sufficiently so that the air treatment matrix desorbs at least a portion of the absorbed vapors and/or gases; control means for selectively activating the heating means and the one or more valves so that the heating means heats the air stream causing the air treatment module to desorb at least a portion of the adsorbed vapors and/or gases while the valve means directs at least a portion of the desorbed vapors and/or gases to the outside space via the second outlet of the chamber.
