WATER HEATING SYSTEM Russian patent published in 2022 - IPC F24D10/00 F24D3/02 

FIELD: heat engineering.

SUBSTANCE: invention relates to the field of heat engineering and can be used heating system control automation. It consists of supply (1) and return pipes (2), air intake (discharge) pipes (3), water drain pipes (4), (20) and a set of heating devices (5), hydraulically connected to each other. An electric valve (6) and a water flow sensor (7) are installed on the supply pipe (1), an electric valve (7) and a water flow sensor (9) are installed on the return pipe (2), an electric valve (11) is installed on the air intake (discharge) pipe (3), and on each of the water drain pipes (4) and (20), respectively, one electric valve (10) and (19) is installed. Under the water drain pipes (4) and (20) there is a heat-insulated tank (12), the lower part of which is hydraulically connected to the heating system through an electric pump (13) and an electric valve (14). The system also contains an electronic control unit (15), the input of which is connected to water flow sensors (8) and (9), and the output is connected to three-way electric valves (6) and (7), as well as electric valves (10), (11) and (14), an electric pump (13) and an annunciator (16). The second outlets of the three-way electric valves (6) and (7) are connected by pipes to a heat exchanger (17) installed in the lower part of a thermally insulated tank (12) having an overflow pipeline (18). As a drive for electric valves (10), (11), (14), (19) and three-way electric valves (6) and (7), electric motors can be used in the water heating system.

EFFECT: increase in energy efficiency and reliability of the water heating system.
