| Outline of Final Research Achievements |
In this work, Impinging Jet Ventilation (IJV) system was evaluated as it has a potential to achieve both thermal comfort and energy saving by forming vertical thermal stratification inside a room. This work involves both laboratory measurement and CFD analysis to clarify mechanics in generating thermal stratification. According to laboratory measurement, it was shown that IJV systems could appropriately mixes air in the occupied zone to obtain thermal comfort, which was impossible by Displacement Ventilation system. This work also showed analysis methodology in using CFD, i.e. appropriate turbulence model and grid layout in analyzing a room controlled by IJV system.
