Abstract. The necessity of the use of technology and analytically summarizes the methods of desalination of seawater and brackish waters. Tasked to investigate the processes occurring in the desalination plant with the continuous process of freezing of ice on heat transfer surface with a film mode of fluid motion.To solve this problem the article deals with mathematical cal model of ice formation on heat transfer surfaces and thermo-electric distiller. The model allows us to estimate the rise time and the thickness of the ice under specified conditions of temperature and flow of water. It is shown that the use of thermoelectric converters allows the flexibility to adjust the mode of ice formation. Solved the problem of determining the maximum thickness of the ice at which freezing is possible film of water flowing through it at a predetermined temperature of the cooling plate and the cooling capacity of the thermoelectric battery.It is established that the performance of thermoelectric opreznitive of the system increases due to the increase in the number of cooled surfaces, and the use of the heat from the hot junction of the converters for melting of ice increases the energy efficiency of the system as a whole.
