Indoor Built Environ 2003 Aug; 12(4):281-291
This paper presents a study of the performance of a floor-supply displacement ventilation system using computational fluid dynamics (CFD). The experiment was carried out in a full-scale environmental chamber with a floor-supply system to obtain reliable flow information for the validation of a CFD program. The validated program was used further to evaluate the performance of the floor-supply displacement ventilation system with different air change rates, diffuser numbers, furniture arrangement, and cooling loads. The evaluation criteria are thermal comfort level and indoor air quality.
