Abstract

L'invention concerne une usine thermoélectrique utilisant l'eau naturelle et la différence de température négative. Cette usine est destinée à mélanger une grande quantité de fluide de travail liquéfié à point de fusion élevé avec une quantité suffisante d'eau naturelle à température normale dans un conteneur sous pression. La chaleur est rapidement échangée et la vaporisation rapide produit une vapeur d'eau sous pression qui sous l'effet d'une turbine génère de l'électricité. Ensuite, la grande quantité de fluide de travail généré par le dispositif de refroidissement sans chaleur à transition de phase simple sert à liquéfier la vapeur d'eau sous pression. La pompe hydraulique logée dans le conteneur sous pression extrait en permanence de l'eau à température normale grâce à l'écoulement vers l'extérieur de l'eau refroidie sous pression et ce, dans le but de générer de l'énergie. Elle l'injecte ensuite dans l'espace d'échange thermique à différence de température négative. Grâce à cette invention, l'usine thermoélectrique nécessite un espace restreint et fournit de l'électricité moins coûteuse, en quantité suffisante et de manière aisée à tout un chacun.
