Available in PDF, EPUB and Kindle. Book excerpt: This study examined the overall system efficiencies and first costs associated with advanced cooling systems in the current market to provide a tool for estimation of system life cycle costs (LCC) that can be used in selecting systems for a given installation. System first costs and an approach for estimating yearly costs of owning and operating are presented. Energy costs are seen as the central factor in the LCC calculation. A method for comparing the efficiencies of systems rated at different evaporator and condenser temperatures is also provided. With the vapor-compression system as the base line case, sample LCC formulations and calculations for an absorption system and a gas engine driven system are given. Modifications by using unconventional energy supplies, heat sources and sinks are considered. Novel and futuristic systems, and heat pump systems are also reviewed. LCC formulations and calculations for these novel systems were beyond the scope of this study although the methods are given. Both unique application and competing cases are identified.

Download or read book Cooling Technologies Technologies and Systems to Guarantee Thermal Comfort in Efficient Buildings written by David Bienvenido-Huertas and published by BoD – Books on Demand. This book was released on 2023-07-19 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cooling systems are a fundamental technology to ensure adequate living conditions in the interior spaces of buildings. As climate change is increasing the outside temperature, cooling systems are experiencing greater use, which can affect the decarbonization objectives established for the built environment. Thus, aspects such as efficient technologies in cooling systems, user operating patterns, and user thermal expectations have a significant impact. In addition, the use of new refrigerants can have repercussions both on the operation of the installation and on the environment. This book is a compendium of research, studies, reviews, and case studies related to refrigeration system design and technology and energy efficiency and thermal comfort.

This book was released on 2019-01-30 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since conventional cooling techniques are increasing falling short of meeting the ever-growing cooling demands of high heat generating devices, thermal systems, and processes, advanced and innovative cooling technologies are of immense importance to deal with such high thermal management. Hence, this book covers a number of key topics related to advanced cooling approaches, their performance, and applications, including: Evaporative air cooling; Spray impingement cooling; Heat pump-based cooling; Modular cooling for photovoltaic plant; Nucleate pool boiling of refrigerants; Transient flashing spray cooling and application; Compressor cooling systems for industry. The book is aimed at a wide variety of people from graduate students and researchers to manufacturers who are involved or interested in the areas of thermal management systems, cooling technologies, and their applications.
Download or read book The Conception and Preliminary Evaluation of Advanced Cooling Techniques for Ground based Electronic Equipment written by D. E. BEARINT and published by . This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present state of the air-conditioning art is reviewed as applied to the cooling of Air Force mobile ground-based electronic equipment. Basic cooling processes are summarized and e aluated for possible application to refrigeration cycles. Recommended cooling processes are applied to thermodynamic-cycle analyses and compared on the basis of power requirements and probable equipment size and weight. Thermodynamic analyses cover mechanical, electrical, and heat-motivated refrigeration cycles and devices. Advisabi ity of employing waste heat from a reciprocating internal-combustion engine to power a cooling system is investigated and found insufficient. It is concluded that present air-conditioning systems, based on the vapor-compression refrigeration cycle, are the most practical and efficient means for the cooling of ground-based electronic equipment. Regenerative Stirlingcycle equipment has the inherent thermodynamic ability to exceed efficiency of vapor-compression cycles, but is presently inferior due to technological limitations. Continued refinement of vapor-compression equipment in areas of compressors, heat exchangers, and air-moving equipment is recommended. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Clear your bookcase of references containing bits and pieces of useful information and replace them with this thorough, single-volume guide to thermal analysis. Air Cooling Technology for Electronic Equipment is a helpful, practical resource that answers questions frequently asked by thermal and packaging engineers grappling with today's demand for increased thermal control in electronics. Superbly organized for quick reference, the book dedicates each chapter to answering fundamental questions, such as: What is the optimal spacing between the printed circuit boards? What is a good estimate of the heat transfer coefficient and the associate pressure drop for forced convection over package arrays? How are heat transfer and fluid flow characteristics in the entrance region different from those in the fully developed region? What is the effect of substrate conduction on convection cooling? The chapters, written by engineers and engineering educators who are experts in electronic cooling, are packed with details and present the latest developments in air cooling techniques and thermal design guidelines. They provide problem-solving analyses that are jargon-free, straightforward, and easy to understand. Air Cooling Technology for Electronic Equipment is a handy source of technical information for anyone who wants to get the most out of air cooling.

Available in PDF, EPUB and Kindle. Book excerpt: The last two years have witnessed a continuation in the breakthrough shift toward pulse tube cryocoolers for long-life, high-reliability cryocooler applications. New this year are papers de scribing the development of very large pulse tube cryocoolers to provide up to 1500 watts of cooling for industrial applications such as cooling the superconducting magnets of Mag-lev trains, coolmg superconducting cables for the power mdustry, and liquefymg natural gas. Pulse tube coolers can be driven by several competing compressor technologies. One class of pulse tube coolers is referred to as "Stirling type" because they are based on the linear Oxford Stirling-cooler type compressor; these generally provide coolmg m the 30 to 100 K temperature range and operate ^t frequencies from 30 to 60 Hz. A second type of pulse tube cooler is the so-called "Gifford-McMahon type. " Pulse tube coolers of this type use a G-M type compressor and lower frequency operation (~1 Hz) to achieve temperatures in the 2 to 10 K temperature range. The third type of pulse tube cooler is driven by a thermoacoustic oscillator, a heat engine that functions well in remote environments where electricity is not readily available. All three types are described, and in total, nearly half of this proceedings covers new developments in the pulse tube arena. Complementing the work on low-temperature pulse tube and Gifford-McMahon cryocoolers is substantial continued progress on rare earth regenerator materials.
