Component for sound absorption and air conditioning

Abstract

The invention relates to a component for sound absorption and air conditioning ( 2 ), which is characterized in that a sound-absorbing planar structure ( 1 ) is coated with photocatalytically active material that can be irradiated by UV light sources ( 3 ), wherein the air can be guided along the planar structure ( 1 ) and/or through the planar structure ( 1 ). The component thereby has a front side facing towards a room ( 5 ) and a rear side facing away from a room, the rear side being coated with photocatalytically active material.
