Description
Describes research into local indoor air quality (IAQ) and thermal comfort in an office under six kinds of air diffusion for summer cooling conditions. The discomfort due to IAQ is calculated by the olf and decipol, the units for perceived air quality. Discomfort due to draughts is calculated by a comfort equation accounting for turbulence intensity. The distributions of decipol and draught are computed by an airflow computer program based on a low-Reynolds number kappa-epsilon model of turbulence. States it can be concluded that a fresh air change rate of five is required to maintain less than 20% dissatisfaction due to air quality, even though it is a low-olf office. The percentage of dissatisfied people due to draught is smaller than 15% in the occupied zone in al cases. Outlet locations and diffuser characteristics are very important for indoor air quality and thermal comfort.
