Abstract (en)

[origin: WO2010124765A2] The invention relates to a method for operating a heat recovery device (1), particularly of a motor vehicle, wherein the heat recovery device (1) comprises a working fluid that is condensed by a condenser (5) of the heat recovery device (1) after expanding in an expansion machine (3) of the heat recovery device (1). By opening an inflow cross-section of a working fluid of the exhaust heat recovery device (1) to an expansion machine (3) of the heat recovery device (1), it is possible to increase a heat transfer flow (dQ) from the working fluid to the condenser environment, and to thus ensure the complete condensation of the working fluid in the condenser (5), by immediately increasing a low pressure (pU, pU*) of the working fluid in the region of the condenser (5) and thereby inducing an immediate increase in the condensation temperature (TU, TU*) of the working fluid in the region of the condenser.
