DEVICE AND METHOD FOR THE OPERATION OF A HEAT TRANSFER STATION

摘要

The invention relates to a heat transfer station for transferring heat from a supplier heating network having a first heat-carrying fluid to a customer heating network having a second heat-carrying fluid, wherein the heat transfer station comprises a thermodynamic cyclic-process device having a working medium, inparticular an ORC device having an organic working medium, and wherein the thermodynamic cyclic-process device comprises: a first heat exchanger designed as an evaporator, for evaporating and optionally additionally superheating the working medium by supplying heat from the first fluid, an expansion machine for producing mechanical energy by expanding the evaporated working medium, a generator coupled to the expansion machine for at least partially converting the mechanical energy into electrical energy, a second heat exchanger designed as a condenser, for condensing the expanded working medium and transferring thermal energy from the expanded working medium to the second fluid, and a feeding pump for conveying the condensed working medium to the evaporator by increasing pressure. The invention further relates to a corresponding method for transferring heat.
