Abstract
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 CO/Oselectivity 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 be optionally combined with an oxygen enrichment method. The invention also relates to corresponding devices for carrying out the inventive method.
