Résumé

This article describes one of the solutions of fresh water production by the combined distillation and congelation method at a single heat input (any type of low grade renewable or exhaust heat). While the distillation can be driven by solar thermal or, in certain cases, natural gas combustion heat, the congelation processes performed by the Binary Fluid Ejector Refrigerating System (BERS) at the expense of low grade heat only. Steam from the distiller condenses in the vapor generator and drives Binary Fluid System that produces cold in the ice generator. The congelation process is carried out in a time-dilated manner and with pressure regulation of the freezing ice-salt mixture to obtain the salt concentration in the produced fresh water. In this case, a temperature head in the ice-generating system is minimum, so that the crystallization process approaches a quasi-static state. Freezing is carried out in a multistage way; further water treatment is processed by mixing of the potted water with a distillate. A water desalination is preceded by its liberation from deuterium and tritium ions. Low temperatures in the BERS can be obtained in the two-stage system design. Also, binary fluid mixtures allow increasing the system’s efficiency by changing the components’ concentration in the evaporator and generator of the BERS.
