Résumé

The ventilation rate provided in the Standard UNI 10339 leaves the kind of installation and the air diffusion system out of consideration; in fact the ventilation rate really involved in internal pollutant dilution fluctuates as a function of the air-diffusion system. To consider this effect, in the reviewing of the standard, the concept of ventilation effectiveness has been introduced; it supplies a type of measurement of the ventilation air flow really used for indoor pollutant dilution, compared with the total supply air flow. As use of a qualitative index to express pollutant dilution would be difficult to carry out, a thermal index designed to put the diffuser air induction performance in touch with the air mixing one is proposed. Ventilation effectiveness becomes a parameter for air diffuser selection that considers their performances, in order to achieve the best indoor air quality.
