摘　　要：介绍了一种新型三元工质NH3-H2O-LiBr。通过与常用二元工质NH3-H2O的气液平衡参数的对比,表明NH3-H2O-LiBr三元工质优于NH3-H2O二元工质,适合用于吸收式制冷系统。另外介绍了吸收式制冷的发展及吸收式制冷工质研究的进展。A new ternary working fluid is proposed. The proposed working fluid consists of the ammonia-water working fluid mixture and the lithium bromide. It is indicated that the ternary working fluid, namely , NH3-H2O-LiBr, is better than the binary working fluid, namely, NH3-H2O by comparing the vapor-liquid equilibrium （VLE） parameters of the two working fluids. So the NH3-H2O-LiBr working fluid is suitable to the absorption refrigeration system. The history of the improvement of the absorption refrigeration and advances of research on the working fluids are also introduced.
