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

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering and can be used in automation of heating systems control. Invention consists of supply (1) and return pipes (2), air inlet (discharge) pipe (3), water drain pipe (4) and complex of heating devices (5) hydraulically connected to each other. On supply pipe (1) there is electric blowout (6) and a water flow sensor (7), on return pipe (2) there is electric blowout (7) and a water flow sensor (9), on the air inlet (discharge) pipes (3) and drain water (4) one electric blower (10) and (11) is installed. Under water drain pipe (4) heat insulated tank (12) is located, the lower part of which is hydraulically connected to heating system through electric pump (13) and electric ventilation (14). Besides, it comprises electronic control unit (15), input of which is connected to water flow rate sensors (8) and (9), and output is connected to three-way electric blowers (6) and (7), as well as electric blowers (10), (11) and (14), electric pump (13) and annunciator (16). Second outlets of three-way electrovalent vanes (6) and (7) are connected by tubes to heat exchanger (17) installed in lower part of heat-insulated container (12) having overflow pipeline (18). Motors of electric fans (10), (11) and (14) and three-way electric blowers (6) and (7) in the proposed water heating system can be electric motors. Vessel (12) can be installed on heat-insulating base, on sides is covered with layer of heat insulation and on top is closed with cover from heat-insulating material. Container (12) can be made of strong, porous, heat-insulating and waterproofing material.

EFFECT: technical result is increase of energy efficiency and reliability of water heating system.
