- Abstract
Achieving a good indoor air quality in already built schools has been a challenge during the last decades. Different solutions have been proposed as an alternative to natural ventilation by opening windows. In this article we propose a simpler approach but yet effective to solve the problem. Using hybrid ventilation between hygroscopic air vent and a window fan can reduce drastically the indoor pollution. In fact, during the experimental campaign we have measured and calculated lower CO2 levels (aprox.1200 ppm) while in the non-ventilated classroom these values were approaching 2500 ppm. The humidity was also a parameter that needed to be monitored as it can influence the indoor environment. The calculations demonstrated that for 30 pupils in a classroom an airflow of 600 m3/h is the ideal solution.
