DISTRIBUTED BUILDING-INTEGRATED CARBON DIOXIDE EXTRACTION SYSTEM REDUCING FRESH AIR REQUIREMENTS

摘要

An arrangement extracting carbon dioxide from room air within a building producing a stream of concentrated carbon dioxide with a concentration of 0.5% to 100% based on cyclic adsorption/desorption process, such as a temperature-vacuum swing or a temperature-concentration swing process, on a solid sorbent material, comprises one or multiple units deployed in at least one or several of individual rooms (11) of the building (10) which directly extract the carbon dioxide from the air concentrated in the room in which they are installed. The units (12) being connected to small pipes (13) which remove the stream of concentrated carbon dioxide collected within the individual units (12) from the inside of the building and the units being composed of a rigid or flexible case containing the sorbent material.
