This edition of the book on Refrigeration and Air-conditioning lays emphasis on the new alternative refrigerants being used today and explains their properties. Summary Of The Book This book has been written keeping in mind the present trend in the relevant industry. It covers the thermodynamic properties of alternate and mixed refrigerants fairly thoroughly. The new type of refrigerants R12 and R134 are given greater attention. To explain the relative advantages, detailed comparison is made between HydroChloro-Fluoro-Carbon (HCFC), R22 and Hydro-Fluro-Carbon (HFC) alternatives like R410A and R407C. Comparison is also given between HCFC, R123, and the HFC alternative R245fa. Features like state-of-the art design of compressors, evaporators, cooling coils, cooling towers, condensers, ice plants, and cold storages are explained with illustrative examples. Topics like properties of pure substances, vapour pressure relationships, and equation of state are dealt with. There is a new section on Installation, Service, and Maintenance of Scroll Compressors. More information on Comfort Air Conditioning with Comfort Chart is given. Other features include calculations of latent heat of vaporization, internal energy, enthalpy, and entropy. Applications of Industrial Air Conditioning with HVAC applications like Tunnel Ventilation, Mine Ventilation, and Station Air-Conditioning have been given higher coverage. The above features are covered in the 24 chapters. In addition, the book also includes Properties of Moist Air, Psychometry of Air-Conditioning Processes, Solar Radiation, Heat Transfer through Building Structures, Load Calculation and Applied Psychometrics, Transmission and Distribution of Air, Fans, Refrigeration and Air-Conditioning Control, and Application in Food Refrigeration processing. Pedagogy includes 144 Solved Examples and 158 Practice Problems.; Table of Contents Chapter 1. Introduction Chapter 2. Refrigeration Machine and Reversed Carnot Cycle Chapter 3.
