Change in the Temperature Indicators of the Individual Thermal Point by Adjusting the Rotational Speed of the Asynchronous Engine

The article is dedicated to the problems that arise during the operation of individual heating points associated with the frequent failure of control valves. An individual heating point is a component of a district heating system that connects the main network with the building’s own heating system. At the initial stage, a mathematical model of an operating facility was developed and investigated, the temperature of the coolant of which is controlled using a control valve available at the facility. As an alternative option to increase the reliability of the object as a whole, it is proposed to use a frequency-controlled electric drive, instead of a control valve operating according to the developed optimal algorithm. The implementation of the proposed solution will not require a change in the layout of the room, since it is proposed to install a frequency converter on a pump already present in the structure of an individual heating point. The solution and study of the task was carried out by simulation modeling in the Matlab Simulink environment. The results obtained allow us to conclude that the proposed solution is appropriate.
