Aqueous-based working fluids containing several salts or their mixtures concerning primarily lithium bromide have been of much interest for the application to absorption coolers, absorption heat transformers, and absorption heat pumps. The vapor pressures of water + lithium chloride + ethylene glycol and water + lithium chloride + lithium bromide + ethylene glycol (LiCniBr mass ratio 1:1) (H{sub 2}O/C{sub 2}H{sub 6}O{sub 2} mole ratio 10:1) were measured in the temperature ranges from 306.65 to 394.90 K and from 308.10 to 398.20 K and in the absorbent concentration ranges from 11.20 to 45.15 mass % and from 10.01 to 54.17 mass %, respectively. The experimental values were correlated with an Antoine-type equation, and the overall average absolute deviations between the experimental values and the calculated values were found to be 1.65% and 1.03% for the two systems, respectively.
