SE-2415 -- Application Criteria for the Air Diffusion Performance Index (ADPI)

Conference Proceeding by ASHRAE, 1976

Paul L. Miller

Full Description

Over the years ASHRAE has sponsored many projects concerned with human comfort and room air diffusion. A series of such projects was initiated at Kansas State University in 1965 to determine the factors which effect air diffusion in rooms using ventilating ceilings, circular ceiling diffusers, high-side wall grilles, sill grilles, 1ight troffer diffusers and slot diffusers. These projects resulted in a number of papers publ ished by ASHRAE which indicate that the air diffusion performance index (ADPI) is a sensitive, valid single-number rating index for air diffusion performance (1-8). The procedure for determining this index has been simplified so that it can be used as a manufacturer1s specification of performance as well as a design criterion.
