Frosting for Air Source Heat Pumps: Research, Case Studies, and Methods provides a comprehensive account of the latest research, analysis, and modeling methods into limiting frosting and maximizing efficiency. This 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 showcasing 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.

Frosting and Icing for Sustainable Energy Use in Engineering Applications provides a compendium of innovative case studies for mitigating impacts from frosting and icing on energy.This book first clarifies the mechanisms of frosting and icing, outlining modeling options, and control techniques. Next, a series of experimental examples show the effects of frosting at different scales of energy production, from ambient air vaporizers to wind turbines, and demonstrate how to control these for maximum efficiency. Finally, the mechanisms and mitigation of frosting are examined in a variety of infrastructure scenarios, including sustainable food storage and efficient high-speed railways. Combining the theoretical fundamentals of frosting and icing with a huge range of real-world case studies, this resource shows how to limit energy loss to these effects in key areas of engineering.

Defrosting for Air Source Heat Pumps: Research, Analysis and Methods presents a detailed analysis of the methods, processes and problems relating to defrosting, a necessary requirement to maintain the performance of ASHP units. Readers will gain a deeper understanding of control strategies and system design optimization methods that improve the performance and reliability of units. The book discusses the most recent experimental and numerical studies of reverse cycle defrosting and the most widely used defrosting method for ASHP. Techno-economic considerations are also presented, as is the outlook for the future. This book is a valuable resource for research students and academics of thermal energy and mechanical engineering, especially those focusing on defrosting for ASHP, heating, ventilation and energy efficiency, as well as engineers and professionals engaged in the development and management of heat pump machinery.
