FIELD: heating.
SUBSTANCE: thermodynamic circuit includes three heat exchangers (W1, W2, W3), separator (4), turbine (2), coupler (5) and bypass pipeline (31). The first heat exchanger (W1) for generation of the first heated or partially evaporated flow (15) of working medium by heat transfer from thin flow (12) of working medium. The second heat exchanger (W2) for generation of the second flow (18) of working medium by partial evaporation or additional evaporation of the first flow (15) of working medium using the heat that is transferred from external heat source (20). The third heat exchanger (W3) for full condensation of thin flow (12a) of working medium. Separator (4) for separation of liquid phase (19) from vapour phase (10) of the second flow (18) of working medium. Turbine (2) for exhaustion of vapour phase (10), conversion of its energy to useful form and generation of thin vapour phase (11). Coupler (5) for generation of thin flow (12) of working medium by combining liquid phase (19) and thin vapour phase (11). Bypass pipeline (31) for bypassing vapour phase (10) of turbine (2) and the first heat exchanger (W1). Pipeline (31) is branched from pipeline (32) between separator (4) and turbine (2) and enters pipeline (30) between the first heat exchanger (W1) and the third heat exchanger (W3).
EFFECT: preventing hazardous pressure pulsations in the circuit during start-up.
