Abstract

The ventilation performance of cold-air distribution systems was investigated for three different designs of ceiling-mounted diffusers. Tests were conducted with internal heat loads, and with and without furnishings. The local mean ages of air, air diffusion effectiveness, and contaminant-removal efficiency were measured using tracer gas techniques to assess the performance of the ventilation system in maintaining adequate air quality conditions. Air velocities and temperatures were also measured in the occupied region to calculate the air diffusion performance index (ADPI).
