Solubilities of lithium bromide in the water (1) + Lithium bromide (2) + ethanolamine (3) system at three different ratios (w(2)/w(3) = 4.5, 4, and 3.5) were measured by using the visual polythermal method in temperature ranges of(281.35 to 333.55) K, (281.65 to 333.55) K, and (275.45 to 345.95) K, respectively. Each set of experimental measurements was correlated with two least-squares regression equations as a function of temperature. The average absolute deviations between the experimental and the calculated solubilities were less than 0.04%. Vapor pressures of the water + lithium bromide + ethanolamine system (LiBr/H2N(CH2)(2)OH mass ratio 3.5/1) were also measured by a boiling point method in the temperature range of (319.75 to 418.35)K and in the absorbent concentration range of (50.0 to 79.3) mass %. The experimental values were well correlated with an Antoine-type equation, and the overall average absolute deviation was found to be 0.85 %. These experimental results indicate that the mixture studied can be used as a new working fluid in an absorption chiller.
