Download or read book Spectrally Selective Surfaces for Heating and Cooling Applications written by Claes G. Granqvist and published by SPIE Press. This book was released on 1989 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Tutorial Text covers coatings and surface treatments for energy-efficient windows of many different kinds, for solar collectors, and for radiative coolers. The desired spectral properties of these surfaces are introduced through a discussion of the radiation that prevails in our natural ambience. Emphasized are materials options, coating techniques, experimental data on optical properties, theoretical models for pertinent materials, and optimization studies with regard to practical applications. The book should be of interest to people working R&D in industry, universities, and national and international institutions who are engaged in issues related to energy efficiency and solar energy utilization.

Available in PDF, EPUB and Kindle. Book excerpt: In this report, summarizing work accomplished during the fourth quarter of the research under NSF -GI -41095, we address two major topics. The first is the progress in making and testing coatings. The second is a critical study of the theory of fixed geometry collectors as applied to the Trombe Cusp and The Winston Collector. Materials selection for absorber designs employing silver and various dielectrics have been done, based on the adherence of the films to the substrate and the stability of the materials at temperatures exceeding 150°C. All of the tasks in assembling and testing the measurement equipment are now completed. The calorimeter for hemispherical emittance measurements has been tested with selective coating samples that have been calibrated by spectral reflectance measurements as well as other known materials. Considerable progress has been made in unifying the theory of "fixed" geometry collectors having low radiative balance flux concentrations (X). It is shown that the basic Trombe cusp, a collector of unit concentration and 27r solid angle acceptance, and as modified by Meinel in this study, merges with the family at the other extreme, the. Winston double parabolic cusp, with the "truncated" Winston designs and the Trombe41einel designs occupying the same acceptance angle -concentration domaine. A graph showing the interrelationships of various fixed collector designs is presented. Some optical ray photographs are presented of three designs within the family of collectors, showing some of the interesting optical geometry of the image which results.

Available in PDF, EPUB and Kindle. Book excerpt: The numerous choices we have for obtaining absorber surfaces with (ale) values greater than 25 are discussed. (a/e) as high as 75 appears possible. These high (a/c)coatings suffer from low values for absorptance. We establish a requirement for a coating as having absorptance 0.90, with (a/c) 20.Direct measurement of hemispherical emittance by means of a simple instrument is discussed, based on accurate heat flow measurements through a heated sample. A set of lifetime thermal testing procedures is outlined. Tests in progress indicate no degradation of the coating sample to dale. .. .Discussions given of the question of how best to utilize selective -surfaces. A Fourier analysis of solar input on different types of days indicates the possibility of using the powerful method of MTF analysis to determine system performance. MTF curves for solar flux are given. Studies of various flat plate collector configurations shows that the combination of selective absorbers and selective windows offer significant gains for high temperature operation. flux balance diagrams for 320°F are given.

Download or read book Advances in Solar Energy Technology written by H.P. Garg and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of writing the three volume 'Advances in Solar Energy Technology' is to consolidate all the relevant latest information available in the field of solar energy (applied and theoretical in nature) and to as sist both the students ( i. e. undergraduate, postgraduate, research scholars etc.) and the professionals (i.e. consulting, design and contracting firms). I have discussed each and every topic in depth rather than a cursory overview. All the material required on a particular topic is included in the chapter and I have wherever possible given useful relationships in equation, graphical and tabular form. It is hoped that this completed Solar Energy Technol ogy will serve the best source material in this field. The first chapter deals with the evacuated tubular col lecors suitable to operate at a temperature of about 150°C with a daily energy collector efficiency in excess of 40 per cent. These collectors thus would be useful for efficient operation of Solar Airconditioning System, Power Generation and Process Heat System. Various advanced features like vacuum insulation, selective black coating, anti-reflective coating, heat pipe, cusp reflector, etc., used in designing this advanced type of collector are discussed separately in this chapter. Transient mathematical model for its perfor mance prediction and different designs of evacuated tubular collectors commercially produced in different countries of the world are described in brief to give the reader a good picture about their scopr and working.
