DEVICE OF AUTOMATIC CONTROL OF THERMAL ENERGY CONSUMPTION (VERSIONS) Russian patent published in 2015 - IPC G05D23/01 F24D3/02 

FIELD: heating.

SUBSTANCE: device of automatic control comprises a supply and a return pipelines, an elevator and a heating system, and also a pump, a control unit, a unit of outdoor air temperature measurement, coolant temperature measurement units installed on supply and return pipelines. A control valve is installed in the supply pipeline, its outlet is connected to the first inlet of the elevator, and the outlet - via a check valve is connected to the return pipeline. A circulating pump with an inlet is connected to the return pipeline, and by the outlet - via a check valve is connected to the outlet of a water-jet elevator. Or in parallel to the return pipeline between the second inlet of the water-jet elevator and the second unit of coolant temperature measurement there is a circulating pump installed. Or in parallel to the return pipeline between the outlet of the water-jet elevator and the first unit of coolant temperature measurement there is a circulating pump installed.

EFFECT: reliable and long-term operation in main and redundant modes of operation due to provision of a stable hydraulic mode and permanent flow of coolant circulation in a heating system.
