Abstract

La présente invention concerne une centrale électrique qui transforme l'énergie thermique en énergie électrique, en conséquence de son utilisation possible pour le chauffage et le refroidissement. Le système de cette centrale électrique est fondé sur le cycle de l'eau; à l'intérieur, le liquide passe de l'état liquide à l'état gazeux et inversement de façon cyclique au fil du temps et systématiquement dans un système fermé. Ces transformations sont la conséquence d'un échange thermique avec la source de chaleur ou la source froide, associé respectivement à l'évaporation sur l'évaporateur (1) ou à la condensation sur le condenseur (2). Le système tire parti de la forte élévation d'altitude entre le condenseur (2) (en haut) et l'évaporateur (1) (sur la base), et cette élévation est utilisée pour produire de l'énergie électrique sur le « groupe avec vanne, turbine et générateur électrique » (6) et est également utilisée pour créer un vide à l'intérieur du système avec l'ouverture des vannes (5), en amenant naturellement le liquide vers le réservoir externe (4). Le « groupe avec vanne, moteur à vapeur et générateur électrique » (7) est utilisé pour interrompre le système et utiliser la différence de pression pour créer de l'énergie électrique. Le système permet le stockage d'énergie sur les réservoirs intermédiaires (3), sur l'évaporateur (1) et sur le condenseur (2).
