Popular for close to four decades, this book: Refrigeration and air Conditioning has been enriched with significant value-adds in its previous editions. Carrying on the legacy, the fourth edition discusses the recent developments and emergence of non-cfc refrigerants including R 600A (isobutane). these refrigerants Act as Substitutes for cfcs that attributed to Ozone layer depletion and global warming potential. The latest refrigerants used in the industry are also covered in the book. This book caters to the Refrigeration and air Conditioning courses offered to undergraduate and postgraduate students of Mechanical Engineering. It will also serve as a useful reference to research students and practicing engineers. Key highlights: 1. New! Hfc R 32 (difluoromethane) and its comparison with R 22 and R 410A 2. New! Sections on inverter technology and uses of hfc R 134A and its comparison with hcfc R 123 3. Examples based on design of compressors, Condensers, evaporator, etc. 4. More than 300 solved and unsolved problems 5. Recommended in the latest AICTE model curriculum.
