Two air terminal devices (ATD) for personalized ventilation (PV) were developed: RoundMovable Panel (RMP) and Headset-Incorporated Supply (Headset). The performance of theATDs was tested at three combinations of room air temperature and supply personalized airtemperature: 23/23C, 23/20C and 26/20C, respectively, and at different flow rates ofpersonalized air, ranging from 5 to 15 l/s for RMP and from 0.18 to 0.5 l/s for Headset. Abreathing thermal manikin was used to evaluate the inhaled air quality achieved with thedeveloped ATDs as well as the performance in regard to thermal comfort. The results revealedthat inhaled air consisting of 100% personalized air was achieved with the RMP and up to80% with the Headset. The change in room temperature that would have affected whole-bodyheat loss equivalently ranged from less than 0.5-2.2 K for RMP and almost 0 K for theHeadset.
