carbon dioxide concentration

The paper documents the determination of the required volumetric air flow of the ventilation unit for the purpose of ventilating the selected lecture room. The contribution briefly characterizes the legislative requirements valid in Slovakia and Poland. Particular attention was paid to the regulations of the Ministry of Health, Ministry of the Environment, Ministry of Transport and Construction of the Slovak Republic and regulations of the Ministry of Education and Sport, Ministry of Infrastructure and European standards.

As part of the research entitled "Experimental determination of the optimal amount of air in a selected room in Ukraine based on measurements of carbon dioxide concentration", an experimental measurement was performed in a selected school room in Ukraine. The aim of the experimental measurement was to determine the course of air temperature, relative humidity and carbon dioxide concentration during the teaching process. From the carbon dioxide concentration curves, it is possible to calculate the required ventilation intensity in the room.
