Download or read book Calibration Procedures for Hot Boxes written by S. Yuan and published by . This book was released on 2002 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete calibration on any Guarded or Calibrated Hot Box is critical for improving the accuracy of U-factor measurements of fenestration products. Any heat transfer that does not occur directly through the test specimen should be determined from the results of detailed calibration experiments. In addition, appropriate test conditions should be verified using national laboratory traceable calibration standards. In this paper, complete sets of calibration procedures using the University of Massachusetts Research Calibrated Hot Box under both the ASTM and ISO test methods are presented. Both the ASTM and ISO procedures include calibrations of the metering chamber extraneous heat transfer and the test specimen flanking heat transfer. The metering chamber extraneous heat transfer includes the metering chamber wall heat transfer, an insulated surround panel flanking heat transfer and other heat losses such as those through gaskets, mechanical fasteners, and less obvious heat transfer paths through the metering chamber wall or surround panel edges. The calibration procedure was conducted under ASTM and ISO test conditions. The calibrated heat transfer rates were characterized by the resulting surface temperature difference of the surround panel and the metering chamber the chamber wall thermopile voltage. In addition, the ASTM calibration procedures included the surface heat transfer coefficients calibrated using a plastic-faced Calibration Transfer Standard (CTS), and the ISO calibration procedures included the total surface thermal resistance calibrated using two Calibration Panels (CP).

This book was released on 2019-10-01 with total page 1114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantifying exergy losses in the energy supply system of buildings reveals the potential for energy improvement, which cannot be discovered using conventional energy analysis. Thermoeconomics combines economic and thermodynamic analysis by applying the concept of cost (an economic concept) to exergy, as exergy is a thermodynamic property fit for this purpose, in that it combines the quantity of energy with its quality factor. Exergy Analysis and Thermoeconomics of Buildings applies exergy analysis methods and thermoeconomics to the built environment. The mechanisms of heat transfer throughout the envelope of buildings are analyzed from an exergy perspective and then to the building thermal installations, analyzing the different components, such as condensing boilers, absorption refrigerators, microcogeneration plants, etc., including solar installations and finally the thermal facilities as a whole. A detailed analysis of the cost formation process is presented, which has its physical roots firmly planted in the second law of thermodynamics. The basic principles and the rules of cost allocation, in energy units (exergy cost), in monetary units (exergoeconomic cost), and in CO2 emissions (exergoenvironmental cost), based on the so-called Exergy Cost Theory are presented and applied to thermal installations of buildings. Clear and rigorous in its exposition, Exergy Analysis and Thermoeconomics of Buildings discusses exergy analysis and thermoeconomics and the role they could play in the analysis and design of building components, either the envelope or the thermal facilities, as well as the diagnosis of thermal installations. This book moves progressively from introducing the basic concepts to applying them. Exergy Analysis and Thermoeconomics of Buildings provides examples of specific cases throughout this book. These cases include real data, so that the results obtained are useful to interpret the inefficiencies and losses that truly occur in actual installations; hence, the assessment of their effects encourages the manner to improve efficiency. Applies exergy analysis methods for the installation of building thermal facilities equipment components, including pipes, valves, heat exchangers, boilers and heat pumps Helps readers determine the operational costs of heating and cooling building systems Includes exergy analysis methods that are devoted to absorption refrigerators, adsorption cooling systems, basic air conditioning processes, ventilation systems and solar systems, either thermal and PV Discusses the direct application of exergy analysis concepts, including examples of buildings with typical heating, DHW and air conditioning installations

Download or read book The Gauge Block Handbook written by Ted Doiron and published by Createspace Independent Publishing Platform. This book was released on 2014-02-19 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a both a description of the current practice at the National Institute of Standards and Technology, and a compilation of the theory and lore of gauge block calibration. Most of the chapters are nearly self-contained so that the interested reader can, for example, get information on the cleaning and handling of gauge blocks without having to read the chapters on measurement schemes or process control, etc. This partitioning of the material has led to some unavoidable repetition of material between chapters. The basic structure of the handbook is from the theoretical to the practical. Chapter 1: basic concepts and definitions of length and units; Chapter 2: history of gauge blocks, appropriate definitions and a discussion of pertinent national and international standards; Chapter 3: physical characteristics of gauge blocks, including thermal, mechanical and optical properties; Chapter 4: a description of statistical process control (SPC) and measurement assurance (MA) concepts; and Chapters 5 and 6: details of the mechanical comparisons and interferometric techniques used for gauge block calibrations. Full discussions of the related uncertainties and corrections are included. Finally, the appendices cover in more detail some important topics in metrology and gauge block calibration.
