Abstract

L'invention concerne une pompe à chaleur à vapeur efficace et un procédé de supplémentation d'enthalpie d'une vapeur à basse pression et d'utilisation d'une mise sous pression, le procédé consistant : à chauffer la vapeur à basse pression afin d'obtenir une vapeur surchauffée permettant de supplémenter l'enthalpie ; puis, à l'aide d'une vapeur saturée sous pression lorsqu'un appareil de chauffage de matériau (1) chauffe un matériau et ce dernier condense, le volume diminuant rapidement une forte force d'aspiration produite, à aspirer la vapeur surchauffée afin d'effectuer une mise sous pression de pulvérisation de liquide de façon à permettre une utilisation de la vapeur saturée sous pression. En outre, au moyen de l'utilisation d'un surchauffeur à tourbillon (21) et d'un générateur de pression de pulvérisation de liquide en tourbillon (2), la vapeur forme un tourbillon artificiel dans un dispositif correspondant, ce qui permet de renforcer la force d'aspiration de condensation de la vapeur, améliorant en même temps l'efficacité thermique et le taux de compression.
