HEATING POINT OF SYSTEM OF HEATING AND HOT WATER SUPPLY Russian patent published in 2018 - IPC F24D3/08 

FIELD: heating equipment.

SUBSTANCE: invention relates to central heating systems. Thermal point of heating and hot water system comprise supply and return pipelines of heating network. At the same time, inlet pipeline of DHW system, inlet pipe of electricity generating module (ELGM), inlet pipe of heat supply for ventilation systems (TVU) and inlet pipe of heating system (SO) are connected in parallel to heat pipeline supply pipe. Return pipe of DHW system, ELGM return pipeline, TVU return pipeline and SO return pipeline are connected in parallel to return pipe of heat network. First inlet of heat exchanger of the second stage of DHW heating is connected to supply pipe of the DHW system, the first outlet of which is connected to return pipe of DHW system, second outlet is connected to the pipeline of the heated coolant of the hot water supply system, and the second inlet is connected to the pipeline of the circulation line of the hot water supply system. First input of the heat exchanger of the superheater of the Rankine cycle circuit is connected to the supply pipeline ELGM, first outlet of which is connected to the ELGM return pipeline, the second outlet is connected by a pipeline of the working substance in a state of superheated steam of the Rankine cycle to the input of the turbine generator of the Rankine cycle, output of which is connected by a pipeline of waste working substance of the Rankine cycle with the first input of the heat exchanger of the heat exchanger of the Rankine cycle, first outlet of which is connected by pipeline of heated condensate of working substance of Rankine cycle with the second input of heat exchanger of superheater of Rankine cycle circuit. Second output of the heat exchanger of the regenerator of the Rankine cycle is connected by a pipeline of the intermediately cooled working substance of the Rankine cycle to the first input of the heat exchanger of the condenser of the Rankine cycle, the first outlet of which is connected by the pipeline of condensate of the working substance of the Rankine cycle with the second inlet of the heat exchanger of the regenerant of the Rankine cycle. At the same time, a circulation pump is installed on the pipeline for the condensate of the working substance of the Rankine cycle. To the second input of the heat exchanger of the condenser of the Rankine cycle is connected to the cold water supply pipe (Cold Water). Second output of the heat exchanger of the Rankine cycle condenser is connected to the pipeline of the heated coolant of the DHW system with the pipeline of the circulation line of the DHW system. First and second outputs of the control unit of the automated control system of the thermal point (CU) are connected to the control inputs of the turbine generator of the Rankine cycle and the circulation pump.

EFFECT: invention is aimed at improving energy efficiency of substation and expanding its functionality.
