Conference and training rooms, lecture halls, listening rooms, auditoriums

Rooms with good air quality are essential for good, efficient training and the greatest possible learning effect. Poorly ventilated training and conference rooms are often accompanied by poor concentration, tiredness and headaches after a short time. Even if there is ventilation after each lesson, an atmosphere saturated with pollutants (VOCs), viruses, bacteria,  CO2 and odors forms within a very short time - with well occupied places - the often permitted limit values exceeded, even if only for a short time until the next airing.. This is also the reason why many classrooms and conference rooms were equipped with bio climatic air-hygiene devices during the corona pandemic and their high efficiency is proven by measurements of the air quality in the room. For example, Covid-19 viruses were reduced by 99.7%!

In summer, when it is very hot outside, the ozone levels rise sharply. Although ozone is an important product of nature and part of the purification cycle in the air, the level should not be too high. That is why there are daily limit values * and short-term limit values ** for interior rooms which can be significantly exceeded when ventilating if the ozone comes in from outside. Bipolar ionization from abbeo is therefore a sensible investment, since even when the outside temperature is high in summer, the ozone in the training rooms, which is generated by the ionization, is only set to the value that is necessary for a healthy room climate and not the limit values reached! As the graphic below shows, mit 

the temperatures outside in summer, the ozone values also reach a maximum in the late afternoon. The lowest values are in the early morning, which can be explained by the fact that the sun is not yet shining at this time and this is necessary for the production of ozone in nature. 

Daily course of ozone outdoors (summer)


* Daily limit

(“Normal working hours” ≈ 8 hours per day):

The average concentration over the working day must not exceed 35 ppb.

** Short-term exposure limit (KZGW)

daily max. four times 15min up to max. 60 ppb allowed at intervals of one hour.
