Abstract : Localized ventilation was applied frontally to the head and neck of seated, clothed subjects, engaged in a central tracking and peripheral tasks, in a 95F and 50% RH environment. Eight different ventilating jet properties were tested. Thermal and comfort sensations were recorded, and their associated physiological responses were measured, for each subject during each test. In the 95F and 50% RH environment, the average thermal vote of all subjects was between warm and hot, while the comfort vote was between uncomfortable and very uncomfortable. It was possible, by applying local ventilation, to improve both sensory votes towards thermal neutrality and comfortable sensations. The ventilating jet which resulted in the best improvements in sensory votes had a velocity 750 f.p.m. and a temperature 50F at its outlet. Localized ventilation had no significant effects on the heart rate and rectal temperature. (Author)
