This book was released on 2000-06-01 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report evaluates all available vapor-liquid equilibria (VLE) data from low-to-moderate pressures over the normal liquid water temperature range for the highly non-ideal aqueous ammonia solutions spanning nearly a century. The evaluation relies on all complete VLE data comprised of pressure- temperature-liquid and vapor compositions published over the last century to develop a temperature dependent model for the coefficients of the Wilson equation. The computations derived from the temperature dependent model are described by means of the program flowcharts and listings. Graphs of computed minima of the "best" Wilson coefficient pairs illustrate the statistical analysis of the experimental data. Tables of calculated deviations for three sets of Wilson coefficients corresponding to the individual and combined data sets demonstrate the utility of the model equations. Excellent agreement between the experimental and calculated liquid and vapor compositions is found for all but two data sets over the region of rapidly changing vapor composition up to 90 mole % of ammonia. This temperature dependent Wilson model offers a succinct representation of 100 years of what appear to be disparate pressure- temperature-composition VLE data.

Available in PDF, EPUB and Kindle. Book excerpt: Infrared (IR) absorbance spectra were acquired for 18 ammonia vapor pressures. The vapor pressures were generated with 15 gravimetrically prepared aqueous solutions and three commercial aqueous solutions using a dynamic method I.E., EQUILIBRIUM VAPOR CELL (EVC). Background IR spectra were obtained using the vapor pressure of distilled water. The IR absorbance (A) measurements were analyzed by computing ammonia vapor mole fractions (Y) or partial pressures (P) as a function of solution mole fractions (X). The Y versus A furnished a superior data fit over P versus A for the prepared and two commercial solutions. The linear regions of these data fits allowed prediction of Y and P for the third commercial 5% VN ammonia solution. Eight times zero filling of IR interferogram data allowed a more accurate determination of the ammonia spectral band peak positions. The zero filled results were compared to the results with no zero filling. Program listings, analysis results, and IR absorbance spectra were tabulated in an extensive set of appendixes. Titration of two prepared aqueous ammonia solutions demonstrated the reliability of gravimetric solution preparation, as well as showing that storage of an aqueous ammonia solution for a period exceeding 2 years had no significant effect on ammonia concentration.

Download or read book Absorption Chillers and Heat Pumps written by Keith E. Herold and published by CRC Press. This book was released on 1996-01-18 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an in-depth description of absorption chillers and heat pumps, focusing on relatively simple systems that employ working fluids in the liquid and vapor phase. The book provides a thorough explanation of how thermodynamic and transport properties of working fluid mixtures enable them to influence the performance of absorption systems. The student or engineer who is a newcomer to the field will gain a comprehensive knowledge essential for the design and evaluation of absorption systems. This book establishes a solid background in general thermodynamics for the reader. The properties of working fluid mixtures pertaining to absorption working fluid combinations are discussed, and various thermodynamic diagrams are introduced and explained. Water/lithium-bromide and ammonia/water absorption chillers and heat pumps are described, and their features and characteristics are detailed. Measures for improving efficiency are presented, and internal heat exchange options are analyzed. Absorption Chillers and Heat Pumps contains extensive examples. It also includes a demonstration copy of the Engineering Equation Solver (EES) program and program files for all of the examples in the text. Problems are listed at the end of major chapters. This unique book is a superior upper-level textbook for students, and a valuable reference source for engineers.
