Abstract
A 5m×6m×6m large space chamber has been built. Sulfur hexafluoride (SF6) is used to simulate the heavy contaminant gas distribution in large spaces. Two kinds of air distribution, two air change rates, four contaminant gas emission rates and two contaminant releasing forms are performed. While the space is ventilated with a certain air distribution and air change rate throughout each of the experiments, the contaminant gas releases continuously only for a period and then stops, and the contaminant concentration at several places are recorded. The contaminant concentration distributions in different conditions are compared. When the contaminant releasing rate increases, the contaminant starts to accumulate in the lower place.
