Abstract

A waste-heat recovery system may include a waste-heat recovery circuit in which a working fluid is circulatable and which has a high pressure region and a low pressure region. The system may also include a conveying device configured to drive the working fluid, a steam generator configured to evaporate the working fluid, an expansion machine configured to expand the working fluid via mechanical work, at least one condenser configured to condense the working fluid, a container arranged downstream of the at least one condenser, and a divider arranged in a container interior of the container which may divide the container interior into a first sub-chamber and a second sub-chamber. The second sub-chamber may be Tillable with a coolant, which is introducible into the at least one condenser fluidically separately from the working fluid via a fluid line, such that the working fluid is condensable via thermal interaction with the coolant.
