ADMIXING PUMP UNIT IN CENTRAL HEATING SYSTEMS LOCAL NETWORKS Russian patent published in 2017 - IPC F24D19/00 

FIELD: power engineering.

SUBSTANCE: this technical solution relates to power engineering and applicable in area of centralized heat supply system of local and areal heat supply networks. Admixing pump unit in central heating systems local networks is characterized by fact, that admixing pump suction pipe guide branch pipe is welded-in into local area network CHS reverse pipeline against carrier flow, to create overpressure in admixing pump suction pipe, guide branch pipe cross-section area is in two times less than suction pipe cross-section area, to reduce excessive pressure in admixing pump suction pipe, and guide branch pipe on admixing pump pressure pipe is welded-in into local area network CHS supply pipeline along heat carrier flow in order to reduce turbulence in hot and cold heat carriers admixing zone, guide branch pipe cross-section area is twice less than admixing pump pressure pipe cross-section area in order to add additional energy to coolant flow in local area network supply pipe.

EFFECT: centralized heat supply of local and areal heat supply networks.
