Evaluation of Integral Effect of Thermal Comfort, Air Quality and Draught Risk for Desks Equipped with Personalized Ventilation Systems

This work evaluates the integral effect of thermal comfort (TC), indoor air quality (IAQ) and Draught Risk (DR) for desks with four personalized ventilation (PV) systems. The numerical study, winter summer conditions, considers a virtual chamber, desk, different PV systems, seats manikins. Two configurations, two upper lower terminal devices (ATD) distance between them are considered. In this study coupling methodology, using one differential models, is used. heating, ventilating conditioning (HVAC) system performance in evaluated DR room removal effectiveness (?DR) that incorporated an Air Distribution Index (ADI). new index, named Turbulence (ADTI), used to consider simultaneously TC, IAQ, heat (?TC), contaminant (?AQ) (?DR). results show ADI ADTI, generally higher Case II than I, increase when inlet velocity increases, exit located at height 1.2 m 1.8 m, conditions conditions. However, values ADTI.
