Analysis of ventilation rate and concentrations of carbon dioxide in the office

The aim of the article is to establish the necessary air exchange rate in the room at the principal production carbon dioxide calculation and experiment. In order to determine the necessary volume the air flow was made more experimental measurements in selected rooms. From the measured data of concentration CO2 by combination of graphic method and mathematical formulas we can determinate the required air flow which meets the hygiene requirements. The entire computation we can see on the example.

Ventilation and indoor air quality in the classroom

his paper highlights the importance of environmental protection regarding the reduction of energy consumption while keeping the living standard. In low energy houses, up to 80 % of the total heat is consumed for the heating of fresh air for a comfortable environment. The aim of this article is to examine the effect of temperature, humidity, air velocity and concentration of carbon dioxide in regard to the human behaviour in indoor environment with natural ventilation, i.e. without a ventilation device, where ventilation is forced or an air conditioning.
