The modeling and design of advanced absorption cycles calls for numerical fits of the working fluids’ properties. The numerical fits can be readily implemented in computers. Recently, a worldwide search of available properties of absorption fluids was completed. The present work presents numerical fits of the thermodynamic and transport properties of the lithium bromide water solutions uncovered by the search. The range of existing correlations is extended, and the accuracy of the existing fits improved slightly. A simple test for the thermodynamic consistency of the vapor pressure fit is presented and carried out at one isotherm, with good results.Units: Dual
