초록

The invention relates to a method for reducing the carbon dioxide concentration in air of a closed or partially closed unit of space. The inventive method may comprise the steps of removing an air flow from the unit of space, guiding the air flow in a membrane system that may contain at least one membrane module having a CO2/O2 selectivity of greater than 2, removing the carbon dioxide permeated through the membrane, and returning the air flow that has been depleted of carbon dioxide in the membrane system to the unit of space. The inventive method may b...

What is claimed is: 1. A method for the depletion of carbon dioxide in the air from a closed or partially closed unit of space, comprising the following steps: extracting an air stream from a unit of space; feeding the air stream into a membrane system containing at least one membrane module having a CO2/O2 selectivity of greater than 1, wherein the at least one membrane module contains carbon membranes, ceramic membranes, and combinations and/or composites of these membranes; removing permeated carbon dioxide which has permeated through a membrane; ret...
