Resently, Task/Ambient Air Conditioning System is widely used for improving the thermal environment and meeting the individual requirements for thermal comfort condition. The purpose of this study is to clarify the thermal comfort of Task Unit with isothermal air flow. In this study, we carried out the experiments at ambient air temperatures of 24, 26, 28, 30℃ and supply air velocity of 0.34, 0.69, 1.17, 1.77, 2.50m/s using the Task Unit. From the measurement results, the cooling effect of the upper body was confirmed by the thermal manikin experiment. Thermal sensation votes were strongly related with ambient air temperature. Under the 28℃ condition, thermal sensation vote reached nearly neutral by using 0.34, 0.69m/s isothermal air flow. In the preferred velocity conditions, subjects felt the air flow more preferable than fixed velocity conditions. The effectiveness of this Task Unit system was confirmed under moderate high temperature condition.
