Movable partitions show decreasing emissions in chamber study

Many people are concerned about the emission potential of various furnishings, especially those of synthetic construction, placed in modern offices. Many IAQ professionals have blamed some of these furnishings for high levels of formaldehyde and volatile organic compounds. A researcher for Steelcase.

Computer modelling & measurement of airflow in an environmental chamber.

The use of sulphur hexafluoride (SF6), nitrous oxide (N2O) or carbon dioxide (CO2) as tracer-gases have been examined for the measurement of airflow in a two-zone environmental chamber. A series of measurements were carried out to examine airflows through a doorway under natural convection, forced convection and combined natural and forced convection. Results were compared with those predicted using the MULTIC computer program.
