Abstract

Proces prezračevanja je bistven za zagotavljanje kakovosti notranjega zraka, ki mora biti svež, prijeten in neškodljiv za ljudi. To dosežemo z odpiranjem oken ali uporabo mehanskih sistemov, kot so prezračevalni sistemi in klimatske naprave. Pravilno prezračevanje je ključnega pomena za zdravje, produktivnost in dobro počutje ljudi - iz notranjega zraka odstranjuje škodljive snovi in pomaga ohranjati ugodno temperaturo in relativno vlažnost prostora. Z opravljenimi meritvami ugotavljamo koncentracijo ogljikovega dioksida v treh obravnavanih prostorih in način izboljšave stanja. Po izvedenih preračunih ugotovimo, da prezračevalni sistem kljub zadostnem pretoku svežega zraka morda ne zadostuje pogoju števila izmenjav zraka po evropskem standardu SIST EN 15251-2007. Ugotovimo tudi, da ja gradient naraščanja koncentracije ogljikovega dioksida nižji kot gradient nižanja koncentracije z naravnim prezračevanjem in predstavlja efektiven način zagotavljanja dobre kakovosti notranjega zraka v kratkem časovnem intervalu. Uporabljeni merilni instrumenti se po primerjavi specifikacij ne razlikujejo bistveno, kljub temu pa se beleženi podatki koncentracije ogljikovega dioksida nekoliko razlikujejo, kar je pričakovano, saj imata instrumenta različen namen uporabe – strokovni in »amaterski«.

Secondary title: The correlation between ventilation, carbon dioxide concentration and their influence on health, comfort and indoor air quality
Secondary abstract: Process of ventilation is essential for ensuring the quality of indoor air, which should be fresh, pleasant, and safe for humans. This is achieved by opening windows or using mechanical systems such as ventilation systems and air conditioning. Proper ventilation is crucial for health, productivity, and well-being of people, as it removes harmful substances from indoor air and helps maintain a healthy indoor temperature and relative humidity. Through conducted measurements, we assess the concentration of carbon dioxide in three examined spaces and propose improvement measures. After performing calculations, we find that the ventilation system, despite providing sufficient fresh air flow, may not meet the requirement for the number of air exchanges according to the European standard SIST EN 15251-2007. We also discover that the rate of carbon dioxide concentration increase is lower than the rate of decrease achieved through natural ventilation, making it an effective method for ensuring good indoor air quality in a short time interval. The measurement instruments used do not significantly differ based on their specifications; however, recorded carbon dioxide concentration data slightly varies, as expected, due to their different intended purposes – professional and »amateur« use.
