Analysis of ventilation in the selected lecture room – case study

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. In the paper is documented the experimental measurement performed in the lecture room is also documented. The resulting values of the volumetric air flow required for the ventilation of the lecture room, calculated according to legislative requirements, are compared with the value calculated on the basis of the measured course of the carbon dioxide concentration.
