Abstract
The invention relates to a working fluid for a steam circuit process carried out in a device comprising a steam generator, an expander, a condenser, and a reservoir for the working fluid, comprising a working medium that evaporates by the addition of heat in a steam generator, performs mechanical work by expanding in the expander during the steam phase, and condenses in the condenser; an ionic fluid serving as an antifreeze component and having a melting point in the reservoir below the freezing point of the working medium, wherein the decomposition temperature of the ionic fluid is above the evaporating temperature of the working medium in the steam generator.
