DEVELOPMENT AND PRACTICAL APPLICATION OF A CONTROL UNIT FOR A TWO-CIRCUIT SOLAR SYSTEM WITH THERMOSIPHON CIRCULATION LOCATED IN THE CITY OF ALMATY (KAZAKHSTAN)

Abstract

An article describes the development and practical application of control unit of the solar plant, located in Almaty city (Kazakhstan). Such system envisages using an electrical pump for circulation in the transfer medium, connecting a flat plate solar collector with a tank. There has been developed a controller for solar system management, able to control the solar thermal system’s current temperature. With the aim thereof in the proposed system the measurements are carried out from 6 digitizers (DS18B20 Dallas), using 16 wires. Using Dallas sensors and corresponding software it is possible to control the temperature level and heat amount. Usage of 4 digital sensors substantially increase the system control performance and raises data processing speed. There have been considered the possibilities of the configuration of the senstors for Arduino platforms, as well, the solar collector management scheme. This paper scientifically analyzes the work of the new controller for controlling the solar thermal system using 6 digital temperature sensors using the Arduino platform to determine the control of the entire solar thermal system.
