Abstract

L'invention concerne un procédé et des dispositifs destinés à faire fonctionner des installations où circulent des fluides, ainsi que l'utilisation correspondante. Dans des installations de chauffage dans lesquelles circulent des fluides, des ondes énergétiques telles que coups de bélier, vibrations, transmises par des fluides et des composants caloporteurs ou accumulateurs de chaleur, sont absorbées ou amorties par l'intermédiaire d'au moins un corps souple, disposé à l'intérieur ou entre des composants, ou d'un corps solide à mouvement de déplacement, qui est formé par des surfaces structurées et/ou par des matériaux structurés. L'invention a également pour objet un dispositif caractérisé en ce que les élasticités des rappels des ouvertures pour l'absorption des ondes se dégradent par déviation à partir des zones de fluide, au moins pendant une période de dégradation des ondes. En outre, l'utilisation de ce dispositif et du procédé pour l'absorption et la réflexion des impulsions énergétiques dans les composants d'une installation, tels que dispositifs échangeurs, dispositifs d'absorption de l'expansion, condenseur, est pertinente. Ceci correspond pleinement au but recherché, à savoir que des variations énergétiques sont, à la longue, équilibrées ou minimisées de manière stable et définie, même dans le cas de températures particulièrement élevées, notamment lors d'un rayonnement solaire intense et d'une accumulation longue durée de chaleur.
