TRANSFER: DESIGN AND VALIDATION

and validate an experimental room for the study of building interior convective heat transfer. The full-scale room with interior dimensions 16’x12’x10’, was constructed with 18 ” walls and 15 ” floor and ceiling. The facility was elevated 5 ’ above the lab floor and the walls were heavily insulated. All six surfaces were divided into 2’x4 ’ cells with a unique modular heated panel system mounted on the inside of the cells. ASHRAE Standard 51 was employed for volumetric air flow measurement. A water source heat pump provided chilled water to a fan-coil unit which in turn provided conditioned air to the room. A total of seventeen validation tests were performed focusing on volumetric air flow measurement and an overall room heat balance. Analysis was directed at results from a subset of seven experiments ranging from 5-25 ach. Additionally, an uncertainty analysis was performed for all experiments. Findings and Conclusions: For the lower volumetric experiments (<10 ach), initial room heat balance results, coupled with the uncertainty results, fel
