DEVICE AND METHOD FOR CONTROLLING PARAMETERS OF AIR DEPOLLUTION MEANS OF AN ENCLOSURE

摘要

A device (DC) controls parameters of depollution means (MD) of an air treatment plant (IT) supplying an enclosure (H) with outside air and / or recirculated air depending on the position of a power shutter (VA). The depollution means (MD) comprise a sensor (CC) delivering a value representative of the concentration of a pollutant in the enclosure (H) and processing means (MT) capable of estimating this concentration from the value delivered. and an offset value with respect to a reference value. The device (DC) comprises control means (MC) capable of triggering successive placements of the supply flap (VA) in first and second positions for supplying the enclosure (H) respectively with outside air and with air recirculated, then record a first value after recirculation to compare it to the reference value to determine the offset value.
