THE PERFORMANCE OF A CONTINUOUS LINEAR DIFFUSER IN THE INTERIOR ZONE OF AN OPEN OFFICE ENVIRONMENT.

Author(s) : HART G. H., INT-HOUT D.

Summary

LABORATORY TESTING WAS CARRIED OUT TO DETERMINE THE DEPENDENCE OF THE PERFORMANCE OF A CONTINUOUS LINEAR AIR DIFFUSER SYSTEM ON SEVERAL CONTROL VARIABLES. FOR ALL THE TESTS, LOCAL VALUES OF AIR TEMPERATURE AND AIR SPEED WERE MEASURED TO CALCULATE THE AIR DIFFUSION PERFORMANCE INDEX (ADPI). OTHER TESTS WERE PERFORMED TO DETERMINE THE EFFECT OF ACOUSTICAL SCREEN ON THE AIR DIFFUSION PERFORMANCE. THE DATA SUGGESTED THAT THE ADPI IS ONLY A ROUGH FUNCTION OF HEAT LOAD AND THAT ITS VALUES DEPEND STRONGLY ON DIFFUSER SPACING, VOLUMETRIC AIR FLOW AND THE TEMPERATURE DIFFERENCE BETWEEN ROOM AND SUPPLY AIR. THE PERFORMANCE OF THE CONTINUOUS LINEAR DIFFUSER WAS EXCELLENT OVER A WIDE RANGE OF TEMPERATURE DIFFERENCES AND VOLUMETRIC AIR FLOW RATES. THE PRESENCE OF 1.5 M HIGH ACOUSTICAL SCREENS, PARALLEL TO THE AIR BARS, SLIGHTLY REDUCED THE AIR DIFFUSION PERFORMANCE.
