vapour pressures densities and viscosities of the water Lithium Bromide potassium acetate system and water Lithium Bromide sodium lactate system
The Journal of Chemical Thermodynamics, 2006Co-Authors: Antonio Lucas, Marina Donate, Juan F. RodríguezAbstract:Abstract Measurements of thermophysical properties (vapour pressure, density, and viscosity) of the (water + Lithium Bromide + potassium acetate) system LiBr:CH 3 COOK = 2:1 by mass ratio and the (water + Lithium Bromide + sodium lactate) system LiBr:CH 3 CH(OH)COONa = 2:1 by mass ratio were measured. The system, a possible new working fluid for absorption heat pump, consists of absorbent (LiBr + CH 3 COOK) or (LiBr + CH 3 CH(OH)COONa) and refrigerant H 2 O. The vapour pressures were measured in the ranges of temperature and absorbent concentration from T = (293.15 to 333.15) K and from mass fraction 0.20 to 0.50, densities and viscosities were measured from T = (293.15 to 323.15) K and from mass fraction 0.20 to 0.40. The experimental data were correlated with an Antoine-type equation. Densities and viscosities were measured in the same range of temperature and absorbent concentration as that of the vapour pressure. Regression equations for densities and viscosities were obtained with a minimum mean square error criterion.

Design and research of single-effect Lithium Bromide-water absorption chillers using plastic pipes
Energy Conservation Technology, 2020Co-Authors: Zhang Xue-dongAbstract:There were extensive applications of Lithium Bromide-water absorption chillers in industry,but the heat exchanger corrosion and refrigerating capacity loss were very difficult to be solved.In our research,the problem was solved by using plastic heat transfer pipes instead of copper pipes.The plastic heat exchangers and Lithium Bromide-water absorption chillers using plastic pipes were designed.The heat transfer pipes of plastic heat exchangers were polytetrafluoroethylene(PTFE)pipes.The disposal of heat transfer pipes was Archimedean spiral pipes.In addition,the contrast of theoretical heat transfer coefficient and experimental heat transfer coefficient was analyzed.The result shows that the absorber using PTFE pipes instead of traditional metal pipes can be most use value in Lithium Bromide-water absorption chillers.
