WATER HEATING SYSTEM Russian patent published in 2021 - IPC F24D10/00 F24D3/02 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering and can be used in automation of heating systems control. Water heating system consists of feeding (hot) (1) and return (cooled) (2) pipes and connected to them through water three-way electric blowers (3) and (4) respectively supply (5) and return (6) stands with heating devices (7), hydraulically connected to each other, automatic air vent (8) located in upper part of supplying riser (5), electric pump (9), water drainage pipe (10), electronic control unit (11) with depressurisation sensors (12) in form of water detection sensors and annunciator (13). Electronic control unit (11) with depressurisation sensors (12) is connected by means of lines (14). Three control lines (15), (16) and (17) are directed to control three-way electric fan (3) and (4), electric pump (9) and annunciator (13) from electronic control unit (11). Inputs of three-way electrovalves (3) and (4) are respectively connected to supply (5) and return (6) risers. First outputs of three-way electrovalves (3) and (4) are connected to supply (1) and return (2) pipes respectively, and second outputs of three-way electrovalves (3) and (4) are connected by pipes to each other and to the inlet of electric pump (9), the outlet of which is connected to sewer pipe through drain pipe (10).

EFFECT: technical result is simplification of design and high reliability.
