STUDY OF THE RELATION BETWEEN THE CAPACITY OF A HELIOSTATIONARY INSTALLATION AND CLIMATIC CONDITIONS IN THE MANGYSTAU REGION

Abstract

This paper attempts to theoretically investigate the desalination of water by solar distillation with solar preheating. Davis Pro2 weather station was used to determine the meteorological data. Ambient temperature, solar intensity, and wind direction and speed were obtained from the weather station. Mathematical calculations of desalination plant efficiency and thermal performance were performed using Engineering Equation Solver (EES) software, TRNSYS 18.0, and an in-house thermal balance algorithm. By the conducted mathematical calculations, the most efficient configuration of the experimental seawater desalination system was determined. Referring to the calculated data in winter, the heat fluxes for the components of the solar distiller are as follows: between the sun and the glass 15,24 W; between the sun and the water 77,41 W; between the sun and the absorber 171,59 W. Likewise, the similar values in summer are 41,95 W, 213,11 W, 472,40 W, respectively. The maximum solar radiation was 750 W/m2, and the maximum outdoor temperature was 200C. With these weather station indicators, the capacity of clean water before 15:00 hours was 2.5 liters.
