Abstract
This study investigates the effectiveness of Thermally Activated Furniture (TAF) in controlled indoor office environment set up conditions. The TAF included radiantly cooled low-height vertical partitions placed on the front and to the side of a workstation. The study presents the results of two experiments: the first was conducted using a heated thermal mannequin and the second with the help of human subjects. Both experiments were conducted in sequence, using the same experimental facility, referred as the Thermal Comfort Chamber (TCC). The Overall and Local Skin Temperature as well as Heat Flux of the thermal mannequin have been presented. The 22 human subjects were surveyed for their Thermal Acceptance, Sensation, Comfort, and Preference. 16 combinations of TCC Air Temperature and TAF Surface Temperature were investigated for the thermal mannequin and 10 combinations for the human subjects. The Mannequin PMV was compared with the Human AMV. The Cooling Thermal Power of the setup was calculated for all the cases of the Thermal Mannequin study. The results from the two experiments were found to be mutually consistent and indicative of the fact that the TAF operation was effective in providing comfort at indoor air temperatures of up to 28�C.
