Thermodynamic Properties of Ammonia-Water Mixtures for Power Cycles1 E. Thorin,2-4 C. Dejfors,2 and G. Svedberg2 Power cycles with ammonia-water mixtures as working fluids have been shown to reach higher thermal efficiencies than the traditional steam turbine (Rankine) cycle with water as the working fluid. DOI: 10.1016/0021-9614(87)90054-1. The thermodynamic properties for ammonia-water mixture have been generated using MATLAB computer code. The aqueous solution of ammonia is used for not only a working fluid in absorption refrigerator cycles but also working fluids in bottoming cycles of steam power plants and other heat recovering systems. Ammonia–water mixtures have been used as working fluids in absorption–refrigeration cycles for several decades. Determination of dryness fraction. Substances are listed by molecular formula in a modified Hill order; all compounds not containing carbon appear first, followed by those that contain carbon. Chem. Claude Lemaire, Robin L.
