PUMP-MIXING UNIT OF LOW-TEMPERATURE HEATING SYSTEM Russian patent published in 2024 - IPC F24D19/10 F24D3/02 

FIELD: machine building; pumps.

SUBSTANCE: invention relates to pump-mixing units (hereinafter referred to as PMU) of low-temperature heating system for change of heat transfer (heat carrier temperature mode). Claimed PMU of a low-temperature heating system, comprising a circulation pump, combining a supply section and a feed-up section, at that, the PMU is connected to the high-temperature line through the supply control valve and the return control valve, each of which is equipped with a drive having a thermal sensor, supply control valve is located on the mix section, and the return control valve is located on the supply section, according to the invention, temperature sensors, in the supply and return parts of the PMU are located before the supply valve and the return valve, relative to the low-temperature heat carrier circulation direction.

EFFECT: enabling control of a low-temperature heating system with heating devices having high inertia, providing automatic control of the heat carrier flow at a given temperature when the circulation pump is stopped, as well as increasing the efficiency of the low-temperature heating system.
