FIELD: heating. ^ SUBSTANCE: invention relates to heat-power engineering, heat water supply systems and hot-water supply systems for residential buildings and industrial enterprises. Heat water supply system comprises a steam source, direct and return pipelines, consumer heat-water supply network, jet pump with nozzle for active fluid feed, nozzle for passive fluid feed, and outlet branch pipe. Jet pump works as a heat exchanging and circulating equipment. Nozzle for active fluid feed of the jet pump is connected (via pipeline) to the steam source; nozzle for passive fluid feed - to the return pipeline, outlet branch pipe - to the straight pipeline of heat water supply system. The return pipeline has a coolant buffer tank equipped with system of additional heating of coolant coming through the mentioned buffer tank. Also variants of heat water supply system are described. ^ EFFECT: possibility to control temperature and/or flow rate of heat power, transferred to consumers. ^ 12 cl, 6 dwg |
