CENTRAL THERMAL ITEM OF CLOSED HEAT SUPPLY SYSTEM Russian patent published in 2018 - IPC F24D3/08 

FIELD: heating system.

SUBSTANCE: invention can be used in central heating points (CHP) of a closed heat supply system, transferred to a reduced temperature schedule, for the preparation of hot water. Summary of the invention consists in that the CHP contains parallel connected by heated media heaters for the first and second level, connected to the thermal network by heating media, cold water pipeline, hot water pipeline, hot water circulation pipeline, circulation pump, mixing chamber and accumulator tank, while the second level heater output and the first level heater output are connected to the hot water circulation pipeline for intensification of heat exchange in heaters. The mixing chamber is connected to the cold-water pipeline, the input of the first level heater and to the hot water circulation pipeline. The accumulator tank is also connected to the hot water circulation pipeline and installed in front of the circulation pump in the direction of water flow.

EFFECT: improving the quality and reliability of hot water supply when transferring central heat points to a reduced temperature schedule, while maintaining the main equipment unchanged.
