Osadchuk Y. Research of processes in absorption thermotransformers in the mode of receiving water with the use of solar energy

The work is devoted to the study of processes in absorption thermotransformers using solar energy in order to increase productivity and reduce energy consumption in systems for obtaining water from atmospheric air. The scheme of system of receiving water from atmospheric air on the basis of absorption water-ammonia thermotransformers (AVTT) and solar collectors with water as the heat carrier which can solve a problem of receiving water with a heat source from 85 ° C is developed. The numerical values of the minimum required temperatures of the heat source, as well as the dependence of the heat coefficient and power of the circulating pump on the characteristic operating temperatures are obtained. The simulation of heat exchange processes at the gravitational flow of the liquid film and the ascending flow of steam for the case of purification of steamammonia mixture under conditions of variable wall temperatures is performed.
