Abstract
A pressure-temperature-concentration diagram and enthalpy diagram within the temperature range from the eutectic –67,5 oС to 190 oС were developed for lithium bromide water solution – the most widely used absorbent for absorption heat transformers. In the range from 0 to 130 oС calculations were based on experimental data obtained by various authors. At temperatures above 130 oС and negative temperatures experimental data were very limited, so the results were produced by extrapolation.

Keywords: lithium bromide, water solution, pressure of saturated water vapour, enthalpies of solutions.
