Abstract

Un système pour libérer une pluralité de parfums dans un espace fermé comprend une unité de détection, une unité de libération de parfum et une unité de purification d'air. Si un parfum préalablement libéré est détecté par l'unité de détection, l'unité de purification d'air est activée pour éliminer le parfum préalablement libéré avant d'activer l'unité de libération de parfum pour libérer un parfum sélectionné.
