Analysis of roof cooling fans function in several working regimes is presented. The main goal of the research was to define the influence of fan working regime on distribution of air velocity fields. During the different fan speeds, the measurements were conducted in characteristic building sections. Air flow velocity measurements were conducted in were 48 measuring points selected, in 4 hight levels, which totally covered the room. Comparative analysis of air flow velocities showed the effects of fans function in particular zones, as well as potential problems that ventilation system may provide. It was concluded that this fans disposal does not achieve satisfactory results in every experimental setup. Particular fans operation regimes create air flow velocities above the thresholds. The change of fans setup was recommended, as well as use of lower fans working speeds.
