Frosting for Air Source Heat Pumps: Research, Case Studies, and Methods

Frosting for Air Source Heat Pumps: Research, Case Studies, and Methods provides a comprehensive accounting of the latest research, analysis, and modeling methods for limiting frosting and maximizing efficiency. The book begins by outlining the fundamentals of frosting mechanisms, including the condensation and freezing of water droplets. It then provides a wide range of case studies that showcase a variety of surfaces, conditions, and energy generation technologies. Finally, the last chapters demonstrate modeling and analysis of frosting operation before laying out critical considerations for designing a frost control strategy in ASHPs.Building on the theory and studies contained in the author’s previous work Defrosting for Air Source Heat Pumps, this book provides essential and advanced information for understanding and controlling frosting for these sustainable energy sources. Outlines the fundamentals of frosting mechanisms in different circumstances and on a variety of surfacesProvides a wide range of real-world case studies, including demonstrations of analysis and modeling in finned tube heat exchangers and ASHPsDetails a huge collection of experimental and numerical data on reverse cycle defrosting, the most common defrosting methods for ASHPs INDICE: 1.
