The thermodynamic properties at equilibrium, in this case, enthalpy, pressure, temperature, mass
fraction, of working pairs are very important for researchers and in the design of absorption
refrigeration systems. Although some authors have carried out their research in this direction by
setting up empirical formulas, there are unfortunately no charts or easy-to-use diagrams making it
possible to have these properties for the couple H20/LiBr. The aim of this present study is to make
a small contribution by making charts and diagrams available to all, making it possible to quickly
and easily obtain the properties of lithium bromide at thermodynamic equilibrium.
