Heat Supply for Consumers of 1st and 2nd Reliability Categories

This article presents a technical solution for ensuring uninterrupted heat supply to buildings in the event of emergency disconnections from the centralized heating system and non-compliance with standards for providing high-quality heat supply to consumers. This solution is critically important for consumers in the 1st reliability category, as well as for socially significant facilities in the 2nd reliability category, including schools, kindergartens, and similar institutions. The proposed approach involves transforming individual heating substations into active heating substations by installing a backup heat source – an electric boiler – without altering the electrical connection scheme of the building to the power grid. Equipping the heating substation with valves on the supply and return pipelines, a circulation pump, and a water supply line for the circulation circuit from the cold-water supply will enable the autonomous operation of the active heating substation during emergencies in the centralized heating system. Additionally, implementing an appropriate automated control system for the active heating substation will eliminate human error during various operating modes, thereby facilitating the technology of an intelligent active heating substation for the building's heating system.
