Reducing limit-exceeding carbon dioxide (CO2) levels in the classrooms with higher concentration of people, which probably occurs due to inappropriate building modifications (window replacement, thermal insulation, …), and creating an optimal microclimate.

550 m3

Our equipment was tested without any modifications of the building.

With the presence of 40 people in the room, the CO2 level after one lesson reached 3200 ppm. Then we started running the device, and after the next lesson, the value went down almost to the value of the outdoor environment (the Náměstí Svobody Square in Brno) – 900 ppm; by this, we achieved the values complying with the standards without any heat loss, maintaining the relative humidity of the environment.
