A new test chamber to measure VOC emissions under controlled air velocity and turbulence
A new 20 1 glass chamber for the determination of volatile organic compound (VOC) emissions from materials used inside buildings is described. Vertical profiles of air velocity and turbulence are reported for the empty chamber and with different carpet specimens. First tests are described on the effect of air velocity on the emission rate of pure evaporation sources and of a source limited by internal diffusion: they show that the chamber is a valuable tool also for investigating the influence of air velocity on the emission rate. A single experiment shows that the influence of turbulence on the emission rate of an evaporation source is small or negligible. The chamber is connected to a data logger, which records values of temperature, relative humidity and air flow rate every 10 minutes.
