Résumé

An improved system of NH3-H2O-LiBr was proposed for overcoming the drawback of NH3-H2O absorption refrigeration system. The LiBr was added to NH3-H2O system anticipating a decrease in the content of water in the NH3-H2O-LiBr system. An equilibrium cell was used to measure thermal property of the ternary NH3-H2O-LiBr mixtures. The pressure-temperature data for their vapour-liquid equilibrium data were measured at ten temperature points between 15-85°C, and pressures up to 2 MPa. The LiBr concentration of the solution was chosen in the range of 5-60% of mass ratio of LiBr in pure water. The experimental results show that the equilibrium pressures reduced by 30-50%, and the amount of component of water in the gas phase reduced greatly to 2.5% at 70°C. The experimental results predicted much better characteristics of the new ternary system than the NH3-H2O system for the applications.
