This article presents a theoretical justification of the design parameters of a solar desalination plant intended for the extraction of fresh water from brine. A series of conducted investigations revealed the mechanisms of solar energy distribution and the principal heat losses within the components of the solar desalination plant. This made it possible to theoretically determine the interaction between key natural and anthropogenic factors influencing the increase in the environmental efficiency of the water desalination process.

The article develops and tests a physical and mathematical model for optimizing the operation of a multistage condensation and recovery system (CRS) with the aim of improving energy efficiency and environmental safety. The key task of the modeling was to comprehensively describe the thermophysical processes, taking into account phase transitions, in particular the use of latent heat of evaporation.
