Abstract
L'invention porte sur un appareil de désalinisation comprenant: un dispositif de gestion qui lorsque le courant électrique produit par un générateur tel qu'un panneau solaire faiblit, cesse d'alimenter certains moteurs d'un groupe selon un ordre de préférence donné de manière à maintenir un fonctionnement au ralenti; un régulateur du débit de l'eau salée fournie à l'évaporateur fixant la température du fluide le chauffant à un niveau donné ou à un niveau plus bas; un réservoir d'eau salée concentrée par évaporation; et un dispositif de mesure de la quantité d'eau concentrée dans le réservoir. On utilise l'eau salée concentrée pour refroidir le condenseur ou circule la vapeur produite par le chauffage de l'eau salée. Lorsque la quantité d'eau salée concentrée baisse au-dessous d'un niveau donné, le dispositif d'alimentation en eau salée fournit d'avance de l'eau salée à l'évaporateur et l'eau sortant de l'évaporateur vient rétablir le niveau du réservoir d'eau concentrée. Ces dispositions assurent une régulation efficace de la désalinisation.
