DEVICE FOR ESTIMATING THE MASS CONCENTRATION OF FINE PARTICLES CONTAINED IN THE AIR OF A CHAMBER

摘要

The invention relates to a device (DE) intended to estimate a first mass concentration of fine particles contained in the air inside a chamber (H) associated with an air treatment plant (IT). This device (DE) includes: calculation means (MCA) arranged to estimate the first mass concentration as a function of at least one second mass concentration of fine particles contained in the air outside the chamber (H) and supplying said chamber (H) via the plant (IT); a particle-size spectrum of the outdoor air; at least one technical feature; and at least one current operating parameter of the plant (IT), and of the space of the chamber (H).
