Abstract
Impinging jet ventilation (IJV), which supplies a high momentum air jet impinging and spreading over the floor, could be used in both cooling and heating modes. However, as a low-level supply system, the excessive temperature difference between head and ankle levels may exist due to the cool air being directly supplied to the occupied zone. As one type of different personalized ventilation (PV) terminal device, ductless personalized ventilation (DPV) is a self-standing system and doesn’t require an extended air duct. In this study, numerical simulation was used to assess the performance of DPV combined with IJV in office buildings under different operating parameters. The results show that a large temperature difference between the occupant’s head and ankle will be significantly decreased by the application of DPV while not influencing the stratification characteristics of impinging jet ventilation.
