Method and device for the transfer of heat from a heat source to a thermodynamic cycle with a working medium of at least two substances with non-isothermal evaporation and condensation

摘要

Heat from a high temperature heat source 2 is transferred to a thermodynamic cycle 9 where the thermodynamic cycle 9 has a working medium composed of at least two substances with non-isothermal evaporation and condensation characteristics and the temperature of the high temperature heat source 2 is more than the decomposition temperature of the working medium of the thermodynamic cycle 9. Heat from the high temperature heat source 2 is transferred to an intermediate hot liquid cycle 4 through a first heat exchanger 3. The temperature of the working medium in the hot liquid cycle 4 is at about the boiling temperature of the working medium in the thermodynamic cycle 9. Heat is then transferred from the hot liquid cycle 4 to the thermodynamic cycle 9 through a second heat exchanger 5.
