Zoning room air conditioning strategy is based on the idea of controlling the conditions of one zone by supply air and, at the same time, utilizing the stratification of temperature and contaminants in another zone. The aim of this study was to assess the ability of CFD-simulation to predict the supply air flow pattern and the overall performance of the system. The study was based on a series of laboratory experiments and corresponding CFD-simulations. The general flow pattern was correctly predicted, but the simulation typically over predicted the temperature effectiveness and the velocities of the plumes.
