Abstract
The paper shows results of measuring the carbon dioxide distribution in a test room with natural ventilation and high occupant density. The measurements were carried out to see the characteristics of carbon dioxide and indoor air flow and also to find possible measuring positions for carbon dioxide sensors to control indoor air quality. The distribution of the carbon dioxide was influenced by several issues, the disposal of carbon dioxide, the status of the window and the heat emission of the dummies. With an open window and carbon dioxide
emitted, the concentration of the gas varied in a wide range over the room. The highest concentrations were measured below the ceiling, the lowest above the floor, but there was not always a stable stratification. Near the window high fluctuations of the carbon dioxide concentration appeared. The measured values near the wall were also more stable than the values in the middle of the room but comparable to them. Therefore appropriate measuring points for this kind of rooms could be at the wall at breathing height with an adequate distance from the windows
