Over the years, much has been written on the subject of pressure enthalpy. Although much of this material has been geared toward engineering and system design, this book presents the important concepts of pressure enthalpy in a manner that will appeal to the service technician. Each refrigerant has its own properties and these properties are compiled on the pressure enthalpy chart for that particular refrigerant. Pressure enthalpy charts should not be confused with pressure/temperature charts, which only provide information regarding saturated refrigerants. The pressure enthalpy chart enables us to create a complete picture, or "snapshot" of the entire system. With a completed pressure enthalpy plot, we can look at sensible and latent heat transfers, while looking at the major system components...all at the same time. The book starts by reviewing the basic vapor-compression refrigeration cycle, as well as the concepts of superheat, subcooling and the pressure/temperature relationship. The book then turns to pressure enthalpy and the p-h chart, giving an overview of the meaning and purpose for every line on the chart. Simplified charts are used to clarify the explanations. The plotting of actual systems follows next. With the completed plot in hand, we next turn to the evaluation of the system parameters that allow for the calculation of many system characteristics, including system capacity and system efficiency. Once we have learned to plot systems on the chart, we then start looking at systems that are operating with malfunctions such as dirty air filters, refrigerant overcharge, refrigerant undercharge, etc. It is here that the reader can appreciate the power of the pressure enthalpy chart and its usefulness to effectively and accurately start up, troubleshoot and evaluate air conditioning and refrigeration systems.

Designed for scientists and engineers involved in the physical chemistry of antioxidants, the Handbook of Antioxidants contains comprehensive data on the thermodynamics and reactivity of antioxidants. It includes:o bond dissociation energies of antioxidants such as phenols (O-H bonds), aromatic amines (N-H bonds), hydroxyl amines (O-H bonds), thiophenols (S-H bonds) o activation energies and rate constants of reactions of peroxyl radicals with antioxidants o rate constants of reactions of phenoxyl, aminyl, and nitroxyl radicals with RH, ROOH, phenols, thiophenols, amines and hydroxyl amines and o rate constants of reactions of antioxidants with hydroperoxides and oxygen.

Represents the final, complete and revised tables of the CODATA Task Group on Key Values for Thermodynamics. Gives the world's first internationally agreed-upon values for the thermodynamic properties of 151 chemical substances. The work features self-consistent enthalpies, entropies, and other constants as well as their uncertainties. The text also includes the reasoning behind the selection of values presented. Annotation copyright Book News, Inc. Portland, Or.

Recommended values are provided for chemical thermodynamic properties of inorganic substances and for organic substances usually containing only one or two carbon atoms. Where available, values are given for the enthalpy of formation, Gibbs energy of formation, entropy, and heat capacity at 298.15 K (25 C), the enthalpy difference between 298.15 and 0 K and the enthalpy of formation at 0 K. All values are given in SI units and are for a standard state pressure of 100 000 pascal. This volume is a new collective edition of 'Selected Values of Chemical Thermodynamic Properties,' which was issued serially as National Bureau of Standards Technical Notes 270-1 (1965) to 270-8 (1981). Values are given for properties of gaseous, liquid and crystalline substances, for solutions in water, and for mixed aqueous and organic solutions. Values are not given for alloys or other solid solutions, fused salts or for substances of undefined composition. Compounds of the transuranium elements are not included. (Author)

This book is a beginners introduction to chemical thermodynamics for engineers. In the textbook efforts have been made to visualize as clearly as possible the main concepts of thermodynamic quantities such as enthalpy and entropy, thus making them more perceivable. Furthermore, intricate formulae in thermodynamics have been discussed as functionally unified sets of formulae to understand their meaning rather than to mathematically derive them in detail.In this textbook, the affinity of irreversible processes, defined by the second law of thermodynamics, has been treated as the main subject, rather than the equilibrium of chemical reactions. The concept of affinity is applicable in general not only to the processes of chemical reactions but also to all kinds of irreversible processes.This textbook also includes electrochemical thermodynamics in which, instead of the classical phenomenological approach, molecular science provides an advanced understanding of the reactions of charged particles such as ions and electrons at the electrodes.Recently, engineering thermodynamics has introduced a new thermodynamic potential called exergy, which essentially is related to the concept of the affinity of irreversible processes. This textbook discusses the relation between exergy and affinity and explains the exergy balance diagram and exergy vector diagram applicable to exergy analyses in chemical manufacturing processes. This textbook is written in the hope that the readers understand in a broad way the fundamental concepts of energy and exergy from chemical thermodynamics in practical applications. Finishing this book, the readers may easily step forward further into an advanced text of their specified line. - Visualizes the main concepts of thermodynamics to show the meaning of the quantities and formulae.- Focuses mainly on the affinity of irreversible processes and the related concept of exergy.- Provides an advanced understanding of electrochemical thermodynamics.
