英文摘要: Abstract(#br)This study conducted the numerical simulation to evaluate the performance of a ductless personalized ventilation (DPV) combined with radiant floor cooling system (RFCS) and displacement ventilation (DV) system. In the non-DPV cases, DV supplies air at temperature of 16 °C and 20 °C, respectively with a flow rate of 2.4 ACH. In the cases with DPV, DPV supplies personalized air, which is drawn at the height of 0.1 m or 0.2 m above the floor, to the face of a seated occupant at flow rates of 3 L/s, 5 L/s and 7 L/s, respectively. The horizontal distance of 0.3 m is designed between DPV air supply opening and occupant face at the height of 1.2m. For all the cases, the floor cooling temperature is set to 20 °C. The vertical air temperature difference at 1.1 m and 0.1 m (Δ T 1.1−0.1...
