The indoor air quality is one of the main factors influencing the comfort in a building. This subject has already been covered by several studies in the case of adult’s work environment. The research study is focused on the air quality in a primary school classroom and the children’s sensation related to interior comfort. In this article we will present the results of the air quality experimentations when using a ventilation system. The classroom is equipped with a heat recovery unit. In order to perform CO2, temperature and relative humidity (RH) measurements, we used ten portable measurement units. The sensors have been set in different spots of the classroom. The heat recovery ventilation unit had an important influence on the air quality when it was running. The observed result of this phenomenon was that the measures were homogeneously distributed in the classroom instead of being concentrated in different points. Moreover, it was found that with 17 m3/h/pers. the indoor CO2 concentration can be dropped below 1000 ppm. The last part of the experimental study was based on a survey with different question regarding air quality, temperature and noise.
