This paper is reported the results obtained by the experiments which compared the different behaviors of the contaminants (test particles and tracer gas SF_6) between in the space with raised floor HVAC system (RF system) and conventional ceiling diffuser system (CC system). The effects both of normal and diffused floor outlet on the concenteration and distribution of contaminants are also discussed. The main results show that : If contaminants generated in indoor air, 1) Contaminant removal performance is influenced by HVAC system and jet direction of floor outlet. The removal rate in the occupied zone from contaminated source is less in the space with RF system (especially with diffused floor outlet) than with CC system. 2) Contaminant removal efficiency is higher in the occupied zone with RF system (especially with normal floor outlet) than with CC system.
