A partition integrated air distribution system can provide highly personalized environmental control. The supply air is brought up through raised floors and supplied to outlets located on the partition panels. This paper aims to find out the best design of outlets for the comfort of occupants within a personal task area.Real scale experiments were conducted to allow comparison of outlet designs within a personal task area. Experimental results indicate that the location of an outlet is the most critical factor in improving the supply air distribution efficiency of the personal task area. Thermal characteristic comparisons were made between under-floor and partition air distribution system. Experimental results suggest that the partition air supply system is more efficient than the under-floor air supply system in terms of heating. Such a system can allow an occupant to personally control their immediate environment, resulting in higher productivity.
