PUMPING AND MIXING UNIT FOR LOW TEMPERATURE HEATING SYSTEM Russian patent published in 2023 - IPC F24D3/02 F24D19/00 

FIELD: heating systems.

SUBSTANCE: invention relates to pumping and mixing units of a low-temperature heating system for changing heat transfer (temperature regime of the coolant), increasing or decreasing it, and is intended to provide comfortable and economical heat supply for both the entire building and individual blocks of premises, namely for the “warm floor” system. The technical problems to be solved by the invention are to increase the reliability of the pumping and mixing unit, to provide the possibility of distributing the collectors and pumping and mixing unit of the low-temperature heating system to different places, as well as to simplify the repairability of the pumping and mixing unit of the low-temperature heating system. The technical result of the invention is achieved due to the fact that the pumping and mixing unit of a low-temperature heating system has a circulation pump that combines, through the circulation pipes, a supply section combined with the supply pipe and a mixing section combined with the return pipe, while the pumping and mixing unit communicates with high-temperature line through the supply control valve and the return control valve, each of which is equipped with a drive having a temperature sensor, the supply control valve is located in the mixing area near the circulation pipe, the check valve is located in the mixing section, between the circulation pipe and the return pipe. What is new is that one of the temperature sensors is located between the circulation pipe of the mixing area and the coolant return pipe of the low-temperature heating system.

EFFECT: increasing the reliability of the pumping and mixing unit, providing the possibility of distributing the collectors and pumping and mixing unit of the low-temperature heating system to different places, as well as to simplifying the repairability of the pumping and mixing unit of the low-temperature heating system.
