La présente invention aborde le problème consistant à améliorer le confort. Ce procédé de commande est un procédé de commande d'un système de régulation d'écoulement d'air (100). Le système de régulation d'écoulement d'air (100) comprend un dispositif de soufflage d'écoulement d'air (1) et un dispositif d'alimentation (7). Le dispositif de soufflage d'écoulement d'air (1) présente une sortie d'écoulement (24) pour souffler vers l'extérieur un écoulement d'air en ligne droite. Le dispositif de soufflage d'écoulement d'air (1) est capable d'ajuster la vitesse de l'écoulement d'air soufflé à l'extérieur à partir de la sortie d'écoulement (24). Le dispositif d'alimentation (7) est capable de fournir, à l'écoulement d'air soufflé vers l'extérieur à partir de la sortie d'écoulement (24), un composant fonctionnel pour souffler dans l'atmosphère. Le procédé de commande consiste à réguler la vitesse de l'écoulement d'air soufflé vers l'extérieur à partir de la sortie d'écoulement (24) de manière à fluctuer et à amener le composant fonctionnel à être fourni par le dispositif d'alimentation (7) à l'écoulement d'air lorsque la vitesse de l'écoulement d'air est supérieure à une valeur seuil.
