Twenty human subjects were exposed to test room equipped with TE-AD system operating at six different input current supply from 2 A to 7 A. Both objective and subjective measurements were carried out. Results show that with the increment of input current supply to the TE-AD system, subject's thermal response related to indoor condition of test room shifted from warm to neutral. Optimum performance of the TE-AD system was obtained at the input current supply of 6 A, more than 80 of subjects responded in the range of ±1 and meets ASHARE standards of acceptability criteria. Further increase in input current supply deteriorates the cooling performance of the TE-AD system. Economic comparison of the TE-AD system with the existing air conditioning system shows that economic saving of US 127.34/year can be achieved with additional benefits of Freon free, convenient installation, no moving part and reliable operation. © 2015 Published by Elsevier Ltd. %R 10.1016/j.applthermaleng.2015.08.077 %D 2015 %J Applied Thermal Engineering %L scholars5585 %O cited By 42 %A K.
