FIELD: heating.
SUBSTANCE: heating system consists of closed heat transfer circuit filled with working agent in kind of fluid and its steams; it includes evaporator within heat flow conjugated with source of heat energy, it also contains heat supplying duct, condensing heating appliances and reverse heat duct. The circuit contains a fluid separator, compressor and ejector. The diffuser of the ejector is connected with the evaporator by means of a pipeline; the receiving chamber of the ejector is connected with liquid zone of fluid separator via the pipeline, the suction branch of the compressor is connected to the steam zone of the liquid separator through the pipeline, and the pressure branch of the compressor is connected with the working nozzle of the ejector by means of the pipeline.
EFFECT: reduced amount of working agent in system due to low density of steam of working agent in system and due to efficient return of condensed drops of working agent from heating appliances to evaporator by means of circulating steam-gas flow.
