Computational fluid dynamics was employed for evaluation of the local thermal discomfort, the indoor air quality , general thermal consolation indices, cooling energy saving and velocity/temperature gradient around the occupants. Then, the performance of the mixing was compared with standalone UFAD and DDV+ systems. Three possible situations had been considered for the air quantity division between inlet diffusers within the hybrid system. As the results showed the optimum case was obtained by combining UFAD and DDV+ diffusers at 70% and 30% of total air volume, respectively.
