Download or read book Frosting and Defrosting of Air Coils written by Per Fahlén and published by . This book was released on 1996 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frosting adversely affects the performance of air-coils under adverse conditions. This report surveys the literature in this field with applications such as air-source heat pumps, refrigeration cooling and freezing coils, and heat recovery ventilators. Since the heat and mass transfer characteristics of a coil will significantly influence the process of frosting, many references pertain to the dry and wet heat transfer of finned-tube air-coils. Furthermore, the change in pressure drop and air flow caused by frosting is a major factor in determining the drop in coil capacity. Therefore the survey also lists references to coil pressure drop. The report contains a literature survey part, a technical index and an alphabetical author index. The survey part discusses some of the most important references based, among other things, on the frequency with which they appear in the reference lists of other authors. In the technical index, references are sorted according to their relevance on topics such as heat and mass transfer, frosting, defrosting, defrost control, as well as standards and test methods. Finally, the alphabetical author index simply gives all the references in alphabetical order according to the name of the first author. A total of 738 references are listed. In some cases, however, the references may seem rather peripheral to the subject of frosted coils. This is particularly the case regarding practical experience. Such information is often subordinate to a lot of general operational information regarding refrigeration and heat pump equipment. Nonetheless, such references are worthwhile for the researcher to consider since they provide an important link between the engineering and the research communities.

Available in PDF, EPUB and Kindle. Book excerpt: An air-to-air split system residential heat pump of nominal three-ton capacity was instrumented and tested in the heating mode under laboratory conditions. This was the second of a planned series of experiments to obtain a data base of system and component performance for heat pumps. The system was evaluated under both steady-state and frosting-defrosting conditions; sensitivity of the system performance to variations in the refrigerant charge was measured. From the steady-state tests, the heating capacity and coefficient of performance were computed, and evaluations were made of the performance parameters of the fan and fan motor units, the heat exchangers and refrigerant metering device, and the compressor. System heat losses were analyzed. The frosting-defrosting tests allowed the observation of system and component performance under dynamic conditions, and measurement of performance degradation under frosting conditions.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-09-24 with total page 825 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the 8th International Symposium on Heating, Ventilation and Air Conditioning is based on the 8th International Symposium of the same name (ISHVAC2013), which took place in Xi’an on October 19-21, 2013. The conference series was initiated at Tsinghua University in 1991 and has since become the premier international HVAC conference initiated in China, playing a significant part in the development of HVAC and indoor environmental research and industry around the world. This international conference provided an exclusive opportunity for policy-makers, designers, researchers, engineers and managers to share their experience. Considering the recent attention on building energy consumption and indoor environments, ISHVAC2013 provided a global platform for discussing recent research on and developments in different aspects of HVAC systems and components, with a focus on building energy consumption, energy efficiency and indoor environments. These categories span a broad range of topics, and the proceedings provide readers with a good general overview of recent advances in different aspects of HVAC systems and related research. As such, they offer a unique resource for further research and a valuable source of information for those interested in the subject. The proceedings are intended for researchers, engineers and graduate students in the fields of Heating, Ventilation and Air Conditioning (HVAC), indoor environments, energy systems, and building information and management. Angui Li works at Xi’an University of Architecture and Technology, Yingxin Zhu works at Tsinghua University and Yuguo Li works at The University of Hong Kong.
