Abstract

As concerns about indoor air quality increase, there has been a need to develop an accurate method of measuring surface emissions from actual living environments. In this study, a cost-effect and accurate flux chamber for measuring surface emissions was designed, and several tests, including airtightness, sample homogeneity, and recovery, were performed. The flux chamber was reinforced to maintain airtightness without leakage, and samples from the chamber were homogeneous (below 4% of the relative standard deviation) enough to represent the entire chamber. In the case of recovery, the concentration inside the chamber reached 100% of the injection concentration within 50 to 100 minutes. To increase the recovery of the experimental emissions relative to theoretical emissions, the rate at which the concentration changes over time should be used as early as possible when performing measurements. The sample inside the chamber, however, was not sufficiently mixed early during the measuring period; thus, research on how to overcome this methodological limitation is currently being conducted.
