Journal Title: Електромеханічні і енергозберігаючі системи - Year 2018, Vol 4, Issue 44
Abstract
Purpose. To create a comprehensive model that describes the functioning of the control system in the district heating substation. Methodology. We have applied the passive multifactorial experiment with regression analysis for finding the dependence of the internal temperature in the rooms on the temperature of the coolant return pipe, the thermal power of the heating system and the ambient temperature. Results. We have developed the mathematical model, which describes the function of the control system in district heating substation. The adequacy of the model is verified with Pearson’s correlation coefficient, the coefficient of determination, the adjusted coefficient of determination, the standard error of the regression equation, Student’s coefficient. Quality indicators have confirmed that the model has high relevance. Analysis of the mathematical model and response surfaces prove the correctness of the description of physical processes. Statements based on the analysis of the model can confirm this. The outdoor temperature significantly influences the value of the internal temperature in the premises. Since its value determines the operating mode of the heating system. The lower the temperature of the coolant return pipeline and the higher the thermal power, the lower the temperature inside the room. Originality. We have carried out the research of control system of the district heating substation in the conditions of the existing heating process. Practical value. The obtained results can be used to optimize the work of control system of the district heating substation in multi-storey buildings. The model is allowed to find optimal values of the temperatures of the return coolant pipeline, which provide guaranteed heat energy savings.
