Heat Recovery with Commercial, Institutional, and Industrial Heat Pumps presents the basic concepts and thermodynamic behavior of mechanical vapor compression and recompression. It covers both ammonia water absorption and compression/resorption heat pumps.Including theoretical and practical approaches, the book features numerous solved exercises based on real thermodynamic and climatic parameters and case studies with takeaways from on-site experiences to help the reader better identify the advantages and limitations of each heat pumping technology. The book discusses future implementations of heat recovery heat pump technologies that are among the most energy-efficient and environmentally friendly techniques.This book will interest graduate students studying HVAC, thermal systems, and heat pumps. It will also benefit professionals working with heat pumps, industrial process engineers, manufacturers, and research and design personnel.
