Book Description
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 surfaces - Provides a wide range of real-world case studies, including demonstrations of analysis and modeling in finned tube heat exchangers and ASHPs - Details a huge collection of experimental and numerical data on reverse cycle defrosting, the most common defrosting methods for ASHPs

Book Description
This SpringerBrief presents a recent advancement in modeling and measurement of the effect of surface wettability on the defrost process. Carefully controlled laboratory measurements of the defrosting of cooled surfaces are used to reveal the effect of surface wetting properties on the extent and speed of frost removal by melting or slumping. The experiments are accompanied by visualization of frost removal at several defrosting conditions. Analysis breaks the defrost process into three stages according to the behavior of the meltwater. Surface wetting factors are included, and become significant when sufficient meltwater accumulates between the saturated frost layer and the surface. The book is aimed at researchers, practicing engineers and graduate students.

Book Description
This is an open access book.Energy storage systems are the key to the successful energy transition to full renewable energy supply and are more relevant today than ever before. They address numerous challenges of the energy transition at once: stabilise the electricity grids, support the shutdown of power plants, make regionally generated electricity available locally and compensate for fluctuations in renewable energy generation. For more than 15 years now, EUROSOLAR has dedicated the annual International Conference on Renewable Energy Storage (IRES) to this important topic. The conference, which has been organised in partnership with Messe Düsseldorf since 2015, addressed the current state of research and the social, political and legal framework conditions of energy storage technologies from 20 to 22 September 2022, as part of its exhibitions on decarbonised industries.In up to three parallel series of lectures, experts from science, practice, politics and society focused on the current state of knowledge about energy storage.In recent years, more than 4000 visitors attended Energy Storage Europe, the predecessor of Messe Düsseldorf’s decarbXpo and IRES, each year. In plenary sessions, topic-specific lecture series and discussion rounds, around 150 lectures were presented including a large poster exhibition.We look forward to welcoming you to the 17th IRES in 2023.

Book Description
This volume presents refereed papers based on the oral and poster presentations at the 4th International Conference on Renewable Energy Sources, which was held from June 20 to 23, 2017 in Krynica, Poland. The scope of the conference included a wide range of topics in renewable energy technology, with a major focus on biomass and solar energy, but also extending to geothermal energy, heat pumps, fuel cells, wind energy, energy storage, and the modeling and optimization of renewable energy systems. The conference had the unique goal of gathering Polish and international researchers’ perspectives on renewable energy sources, and furthermore of balancing them against governmental policy considerations. Accordingly, the conference offered not only scientific sessions but also panels to discuss best practices and solutions with local entrepreneurs and federal government bodies. The Conference was jointly organized by the University of Agriculture in Krakow, the International Commission of Agricultural and Biosystems Engineering (CIGR), the Polish Society of Agricultural Engineering, AGH University of Science and Technology (Krakow), the Polish Society for Agrophysics under the patronage of the Rector of the University of Agriculture in Krakow, and the Polish Chamber of Ecology.
