Available in PDF, EPUB and Kindle. Book excerpt: The precision and accuracy of guarded and calibrated hot box apparatus have seldom been evaluated, either during the design process or at the performance check stage. Even round robins can supply little information on errors if no theory of the apparatus is available. The purpose of this paper is to consider heat transfer in the apparatus, to supply some rough practical tips to aid in understanding the apparatus performance, even though much more has to be done to reach the same level of knowledge achieved for the guarded hot plate apparatus.

Available in PDF, EPUB and Kindle. Book excerpt: A second generation research calibrated hot box was designed and constructed at the University of Massachusetts's Building Energy Research Laboratory. The hot box was built to meet the test methodologies specified in the American Society for Testing and Materials (ASTM) Standard Test Methods C 976 [1] for calibrated hot boxes and C 1199 [2] for fenestration system hot box test methods.

Available in PDF, EPUB and Kindle. Book excerpt: The 6.10 by 4.27 m (20 by 14 ft) vertical heat flow hot box at the Owens-Corning Fiberglas Technical Center has recently been used to make measurements on a variety of roof/ceiling insulation systems used in the steel bar joist and metal deck construction typical in commercial buildings. Since these systems varied in geometry from one with roof insulation only to one combining roof insulation, a plenum, and an insulated hung ceiling, the sample support needed to be nearly 1.22 m (4 ft) tall. This meant that the extraneous energy flows through this support would be a substantial fraction of the sample energy flow for well-insulated samples. Furthermore, these relatively large flows combined with the variety of system geometries would have required that calibrations be developed for multiple geometries.

Available in PDF, EPUB and Kindle. Book excerpt: Under contract from the National Institute of Standards and Technology, we have developed a prototype design for a miniature guarded hot plate apparatus that can be used to determine the thermal resistance of very small specimens (1 to 3 cm square) of thermal insulation materials at temperatures from -40 °C to +100 °C, with the capability to carry out measurements in air, selected gases, or vacuum. The overall design approach for this apparatus has been published previously. In the present paper, we provide details concerning the thermal design of the apparatus, including discussions of heater designs to promote temperature uniformity of the hot plate, guard designs to control extraneous heat gains and losses, material selection for the components of the apparatus, and techniques for temperature measurements.
