摘要：A novel closed type heat-power conversion system was proposed by integrating the essential principles of both reverse electrodialysis (RED ) power generation technology and absorption refrigeration/heating technology.Besides, the working mediums solutions (consisted of solute and solvent)were found to be one of the vital factors for energy conversion efficiency of this new power generation system.Altogether,nine solutes (monovalent inorganic salts)and seventeen solvents (with the normal bubble point temperature within 40—150℃)have been selected as the focused substances,and their thirteen crucial properties (bubble point temperature, latent heat of vaporization, specific heat capacity,solubility,acentric factor,dipole moment,relative dielectric constant,electric conductance, viscosity,thermal conductance,auto-ignition temperature,flammability limit,and toxicity),have been compared and analyzed.Further, methodology of comprehensively assessing the availability of working mediums for this new heat-power conversion system has been established after finishing a series of discussions that were carried out from the aspects of their fundamental thermophysical properties, transport features, electrochemistry characteristics, and dangerousness.Finally, it is ternary type working mediums that consisted of inorganic salt-solute-modifier,are deduced to be in bright prospect.
