Analiza vpliva prezračevanja in prisotnosti obiskovalcev na onesnaženost zraka v notranjem razstavnem prostoru

Gruden, Lucija (author), Stritih, Uroš (mentor)

Raziskovali smo kakovost zraka v notranjem prostoru muzeja, kjer se dlje časa zadržuje veliko število ljudi. Osredotočili smo se na onesnaževala, ki jih v zrak oddaja človek. Zanimal nas je vpliv gostote ljudi in prezračevanja na vsebnost onesnaževal v zraku. Na podlagi meritev vsebnosti CO2 in aerosolov v zraku, ob prisotnosti ljudi v prostoru smo opazili, da ne glede na način prezračevanja rast enega onesnaževala nakazuje tudi rast drugega. Visoka gostota ljudi je močno vplivala na rast obeh onesnaževal v prostoru, pri tem, da obstoječe prezračevanje ni bilo ustrezno za tako obremenitev prostora.

• Title: Analysis of the impact of ventilation and visitor presence on air pollution in indoor exhibition space

Abstract

We investigated the air quality in the museum's indoor space, where many people spend long periods of time. We focused on pollutants emitted by humans. We were interested in the impact of human density and ventilation on the air pollutant content. Based on measurements of CO2 and aerosols in the air when people are present in the room, we observed that, regardless of the ventilation method, the increase of one pollutant also indicates the increase of the other. The high density of people had a strong influence on the growth of both pollutants in the room, and the existing ventilation was not adequate for such a room load.
