This book was released on 1978 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper describes a procedure for measurement of steady-state heat transfer through the walls of air duct systems under actual operating conditions and configuration. The procedure uses two independent measurement techniques. A calibrated hot box is the primary measurement technique and an airstream temperature-drop measurement provides a secondary technique.

Book excerpt: The accuracy of the thermal transmittance, or U-factor, of a fenestration system measured in a building assembly thermal test facility depends upon the test apparatus, test conditions, operating procedure, and the specimen properties. By conducting the uncertainty analysis of a specific thermal test facility, the measurement uncertainty can be identified and quantified. The estimation procedure for the uncertainty associated with the U-factor result for a test apparatus should be established and reported with the measurement of the U-factors of fenestration products. In a study on the University of Massachusetts Research Calibrated Hot Box, detailed analyses of the elemental uncertainties associated with the basic measurements and uncertainty propagation on U-factor results have been performed. In the analysis of uncertainty ropagation, the Root Sum Square (RSS) method was used extensively. The procedure for uncertainty analysis used for this test apparatus can be used in any ASTM C 1363 hot box thermal test facility including those also using ASTM C 1199 for fenestration U- factor measurements. Using the uncertainty analysis procedure described in detail in this paper, a plastic-faced Calibration Standard Transfer (CTS) is analyzed. The results show a reasonable uncertainty level for the U-factor measurement made using ASTM C 1199.The improvement of the U-factor uncertainty can be achieved by reducing the uncertainties associated with the test specimen flanking heat transfer and the metering chamber extraneous heat transfer in the hot box test apparatus.

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).
