Abstract
L'invention concerne un procédé et un appareil, à grand rendement énergétique, pour le dessalement de l'eau. A partir d'un piege thermique, une thermopompe transfère de la chaleur fournissant la chaleur de vaporisation à de l'eau salée introduite dans une zone d'évaporation. Cette zone est maintenue à une pression inférieure à la pression atmosphérique, de sorte que l'eau salée bout à 5,5 degrés C au moins au-dessous du point ambiant de rosée. La dépression est maintenue dans la zone d'évaporation par une pompe à vide et par condensation de la vapeur dans une zone de condensation d'où l'on collecte l'eau douce. La chaleur de condensation est dissipée dans un piège << froid >> ou grâce à un appareil de refroidissement par evaporation. L'appareil peut fonctionner dans des régions très chaudes ou sur des navires en mer.
