This paper presents a set of detailed experimental data of room airflow with displacement ventilation. These data were obtained from a new environmental test facility at the Massachusetts Institute of Technology (MIT). The measurements were conducted for three typical room configurations: a small office, a large office with partition, and a classroom. The experiment measured the distributions of air velocity, air velocity fluctuation, and air temperature by omnidirectional hot-sphere anemometers and contaminant concentrations by tracer gas at 54 points in the room. Smoke was used to observe airflow. The data include the wall surface temperature distribution, air supply parameters, and the age of air in several locations in the room. Airflow using displacement ventilation is a kind of mixed convection and therefore, these data are especially suitable for validating Computational Fluid Dynamics (CFD) programs for prediction of indoor airflow.
