This paper describes particle image velocimetry (PIV) air flow measurements in a room model of scale 1:10; the model has inlets and outlets across its width. The PIV measurements use three types of tracer particles: water mist, oil mist, and metal powder. The air flow distribution and turbulence intensity are measured by PIV with metal powder tracers in four combinations of inlet and outlet positions.<br>The results are as follows;<br>(1) Among the three tracer particles, metal powder yields the best air flow measurements in the 1:10-scale room model.<br>(2) To obtain uniform luminance, an appropriate tracer particle concentration and increased laser output are required.<br>(3) When the inlet and outlet are located midway across the scale model, the air flow velocity in the room in nearly symmetrical. In this case, air enters straight through the inlet, is sucked into the outlet, and is largely discharged. The air not discharged from the outlet collides with the side-wall of the outlet to forms a symmetrical vortex area.
