    Abstract

    This paper describes the design of a large rotatable thermal test facility of the calibrated hot box type. The facility has a 2.4 by 2.4 m (test specimen dimensions) test section and is capable of 90-deg rotation from a vertical position through to a horizontal position for thermal testing a wide range of building assemblies. Technical details on the design and construction are presented along with a description of the instrumentation and the calibration procedure. Highlights of the design are the crane mechanism for rotating the hot side, the rotating evaporator freezer coil, the rotating hub and follower box system, and the low thermal capacity electric furnace. The calibration procedure includes descriptions of the methods for determining the extraneous heat transfer rates and the results from some initial calibration runs.
