Experimental determination of ventilation efficiency with pulse method

Vsaka bivalna cona v kateri se nahajamo potrebuje zadostno in učinkovito prezračevanje zraka. Tako lahko nemoteno in kakovostno preživljamo čas. S prezračevanjem posledično vplivamo tudi na naše počutje. Zato je pomembno, da v zaprtih prostorih, stavbah uporabljamo sisteme za prezračevanje zraka. Poznamo več načinov prezračevanja, ki so odvisni od naših zahtev. V zaključni nalogi smo se seznanili z vsemi pojmi, ki so ključnega pomena za učinkovitost prezračevanja ter to tudi eksperimentalno določili. To smo storili preko merilne proge s oglikovim dioksidom, ki je bil uporabljen kot sledilni plin. Opravili smo dve meritvi. Razlika med njima je bila v tem, da smo pri drugi meritvi veliko prej izklopili dovod sledilnega plina v komoro in zato tudi dobili različne rezultate, ki smo jih na koncu primerjali.Each living area requires adequate and efficient air ventilation. So we can spend our time smoothly and with more quality. Consequently, ventilation also affects our health. Therefore, it is important to use air ventilation systems in single zones and multiple zones. There are several methods of ventilation that depend on our requirements. In the final thesis, we became acquainted with all the concepts that are crucial for the efficiency of ventilation, and also determined this experimentally. We did this with a carbon dioxide measuring line that was used as a tracking gas. We made two measurements. The difference between the two was that we switched off the tracer gas supply to the chamber much earlier in the second measurement and therefore obtained different results, which we eventually compared
