Merenje kvaliteta vazduha i termalnog komfora u kancelarijama primenom low-cost senzora i monitora
Air quality and thermal comfort measurements in the offices using the low-cost sensors and monitors
Abstract: The subjective experience of the environment where people live defines the comfort of that environment. The elements of environmental comfort are the air quality, thermal comfort, visual comfort, and sound comfort. The air quality in the room where people stay can significantly affect their concentration, i.e., the ability to work and study. The concentration of CO2 in the room is used as an indicator of ventilation, that is, as an indicator of the air quality in the observed room. The thermal comfort defines a state of satisfaction with the thermal environment. The thermal comfort is achieved when the environment properties are such that they ensure the release of body heat within the comfortable limits. This paper presents a part of the air quality and thermal comfort measurement results in the selected office in the Mining and Metallurgy Institute Bor from 2020 to 2022. Based on the analysis of measurement results, it was determined that the air quality in the selected office was satisfactory on an average of more than 90% of the working time, and the thermal comfort on an average of about 60% of the working time.
Izvod: Subjektivni doživljaj sredine u kojoj ljudi borave definiše komfor te sredine. Elementi komfora sredine su: kvalitet vazduha (vazdušni komfor), toplotni komfor, vizuelni komfor i zvučni komfor. Kvalitet vazduha u prostoriji u kojoj borave ljudi može značajno da utiče na njihovu koncentraciju, tj. sposobnost za rad i učenje. Merenje koncentracije CO2 u prostoriji koristi se kao indikator ventilacije, odnosno kao indikator kvaliteta vazduha u posmatranoj prostoriji. Toplotni komfor definiše stanje zadovoljstva termalnim okruženjem. Toplotni komfor je ostvaren kada su svojstva sredine takva da obezbeđuju odavanje toplote tela u granicama ugodnosti. U ovom radu prikazan je deo rezultata merenja kvaliteta vazduha i termalnog komfora u odabranoj kancelariji u Institutu za rudarstvo i metalurgiju Bor u periodu od 2020. do 2022. godine. Na osnovu analize rezultata merenja utvrđeno je da je kvalitet vazduha u posmatranoj kancelariji bio zadovoljavajući u proseku više od 90% radnog vremena, a termalni komfor u proseku oko 60% radnog vremena.
