ABSTRACT:
Working fluid for absorption heat pumps operating at very high temperature, particularly 200.degree. to 1000.degree. C., said working fluid being a mixture of at least two constituents, characterized in that the working fluid is constituted by a mixture of at least two chemical elements, whereof the first called the "solvent" is much more volatile than the others called "solutes" at the temperature of the mixture, the nature and proportions of each of the chemical elements in the mixture being chosen in such a way that the Vapour pressure of the mixture is significantly below that of the first, more volatile chemical element throughout the operating cycle of the working fluid in the pump.
These chemical elements can in particular be metals such as mercury or sodium, or metalloids such as sulphur.
