Alternatives in Refrigeration and Air conditioning highlights the issues related to ozone layer depletion and global warming due to use of conventional cooling technologies and refrigerants in the field of Refrigeration and Air Conditioning (RAC). It describes, simulates and analyzes the alternate technologies and alternate refrigerants from energy and exergy point of view. The unconventional and alternative refrigeration technologies viz. Vapor Absorption Refrigeration, Vapor Adsorption Refrigeration, Evaporative Cooling, Desiccant Cooling, Thermoelectric Refrigeration, Thermo Acoustic Refrigeration, Ejector Cooling, Vortex Tube Refrigeration Systems and Metal Hydride Refrigeration etc. are explored in the subject matter of this book. The combined or integrated approach of some technologies to enhance the performance, waste heat utilization or to increase the arena of its use is also discussed. This book will cater to the needs of the RAC community from the point of view of feasible futuristic options in this area. This book will also serve as a text book for postgraduate students especially of thermal and energy engineering stream and useful to the teachers, researchers, and practicing engineers.
