CIRCUIT ARRANGEMENT FOR RAISING TEMPERATURE OF WATER-HEATING SYSTEM BY MEANS OF HEAT GENERATOR Russian patent published in 2003 - IPC

FIELD: water heating systems for apartment houses and industrial buildings. SUBSTANCE: circuit arrangement has heat generator, heating-system motor-driven water pump communicating with heat generator through injection pipe, delivery and return pipelines provided with individual valves. Valves of delivery and return pipelines are interconnected in parallel so that inlet pipe of valve that provides communication with delivery line of pipeline through its outlet pipe is connected in parallel with inlet pipe of valve whose outlet pipe provides communication with return pipeline; starting end of return pipeline is joined with outlet pipe of heat-transfer apparatus incorporated in most distant user. EFFECT: enlarged functional capabilities. 2 dwg
