Abstract

The paper considers a heating system for a country house, including methods for automation and forecasting of heat transfer. The study is based on the integration of solar panels and hardware to form an automated control system (ACS) that adapts to climatic conditions, time of day and position of solar panels. The system takes into account temperature changes, weather factors and the position of the sun, which allows to minimize heat loss and increase energy efficiency. The use of this system allows to reduce heating costs and ensures environmental friendliness due to the use of renewable energy sources. The automated control and dispatching system for the proposed model of a solar water heating system for a country house is designed to monitor the condition of equipment at individual heating points and allows: to provide automatic control services with up-to-date and accurate information on the operation of the equipment; to carry out operational control over the condition of solar systems and process equipment; to track the exit beyond the permissible limits of instrumental and process parameters of heat transfer of the system; to implement modules for changing the operating parameters of the system, ensuring integration into a single system of access to process data and the current state of the equipment. The control of the position of the heliopanels and the use of temperature, pressure and thermal energy sensors allows you to maintain an optimal microclimate inside the building. The operation of pumps and storage tanks is regulated by the automated control system, preventing overloads and minimizing energy consumption. Such automation capabilities make the water supply system sustainable and energy efficient, especially in conditions of low temperatures and high solar activity.
