Heat Flow below 100°K and Its Technical Applications covers the proceedings of the International Institute of Refrigeration. This release serves the purpose of compiling supplementary materials to the published report by Committee 3, entitled Protection against Ionizing Radiation from External Sources. This text is a compilation of 12 appendices that comprise information for employing the recommendations of ICRP Publication 15. These appendices relate to the sources of external radiation encountered in medical, dental, and veterinary radiology, as well as in industry and research. Some of the information included are on the collision stopping power of charged particles; interpolated values of quality factor; and quality factor as a function of charged particle energy. This compendium then presents materials on conversion factors, neutron sources and shielding, and range-energy curves. The last two materials cover the shielding for beta sources and X-ray and gamma-ray shielding. This compilation will cater those interested in the technical applications of heat flow, as well as to those who have read the ICRP Publication 15 and in need of supplementary materials.

Heat Transfer: Current Applications of Air Conditioning deals with problems and applications of air conditioning. The discussions are organized around non-stationary heat transfer through walls; study of confined rooms or enclosures; calculation of cooling loads; heat transfer with two-phase refrigerants; measurement of thermal conductivity and water vapour permeability of insulating materials; and tests on air handling equipment (room air-conditioners, induction or fan coil air-conditioners). This book is comprised of 60 chapters and begins with an assessment of the unit-system controversy in the United States and the quest for an ultimate resolution. The following chapters explore the resolution of conductive heat transfer problems using the finite element method; thermal behavior of composite walls under transient conditions; thermal and electrical models for solving problems of non-stationary heat transfer through walls; and use of a radiometer to measure the average temperature of a wall. Experimental results for mixed air convection along a vertical surface are also presented. This monograph will be a valuable resource for electronics engineers.

Cryogenic engineering (cryogenics) is the production, preservation, and use or application of cold. This book presents a comprehensive introduction to designing systems to deal with heat – effective management of cold, exploring the directing (or redirecting), promoting, or inhibiting this flow of heat in a practical way. It provides a description of the necessary theory, design methodology, and advanced demonstrations (thermodynamics, heat transfer, thermal insulation, fluid mechanics) for many frequently occurring situations in low-temperature apparatus. This includes systems that are widely used such as superconducting magnets for magnetic resonance imaging (MRI), high-energy physics, fusion, tokamak and free electron laser systems, space launch and exploration, and energy and transportation use of liquid hydrogen, as well as potential future applications of cryo-life sciences and chemical industries. The book is written with the assumption that the reader has an undergraduate understanding of thermodynamics, heat transfer, and fluid mechanics, in addition to the mechanics of materials, material science, and physical chemistry. Cryogenic Heat Management: Technology and Applications for Science and Industry will be a valuable guide for those researching, teaching, or working with low-temperature or cryogenic systems, in addition to postgraduates studying the topic. Key features: Presents simplified but useful and practical equations that can be applied in estimating performance and design of energy-efficient systems in low-temperature systems or cryogenics Contains practical approaches and advanced design materials for insulation, shields/anchors, cryogen vessels/pipes, calorimeters, cryogenic heat switches, cryostats, current leads, and RF couplers Provides a comprehensive introduction to the necessary theory and models needed for solutions to common difficulties and illustrates the engineering examples with more than 300 figures

Low Temperatures and Electric Power covers the proceeding of the symposium entitled ""Cryogenics in Fuel and Power Technology"" which was held in March 24-28, 1969 in London, United Kingdom. Said symposium deals with the improvement of systems for electric power and liquid natural gas delivery. The book takes on the problems of the electric power industry, large-scale refrigeration, and cryogenics, and gives different proposals for superconduction, cooling of systems, transfer of liquid natural gas, heat exchange, and energy storage. The text is recommended for electrical engineers and scientists, especially those who work for the government and aim to improve national power systems and delivery of liquid natural gas.
