Abstract

Ustrezna kakovost zraka v notranjih prostorih je dandanes zaradi boljše zrakotesnosti zgradb vedno bolj pomembna. Hkrati se vedno bolj zavedamo vplivov notranjega okolja na zdravje, produktivnost in splošno počutje ljudi. Posledično je prišlo v zadnjih desetletjih do hitrega razvoja mehanskih prezračevalnih sistemov, ki omogočajo tako menjavo zraka v notranjih prostorih, kot tudi uravnavanje temperature in vlage. Ker pa mehansko prezračevanje predstavlja visoko energetsko porabo, je naravno prezračevanje odlična alternativa, ko stremimo k boljši energetski učinkovitosti. Zaradi nepredvidljivosti in vpliva zunanjega okolja pa je določitev učinkovitosti naravnega prezračevanja otežena. Eden izmed bolj uveljavljenih načinov je uporaba sledilnega plina, s katerim merimo naravne zračne tokove, brez da bi posegali v sam vzorec toka. Namen te naloge je pregled in primerjava metod, ki temeljijo na uporabi sledilnega plina, ter določitev njihove natančnosti in primernosti za praktično izvajanje.

Secondary title: Methods for determining the efficiency of natural ventilation using tracer gas
Secondary abstract: Adequate indoor air quality is becoming increasingly important today due to the better airtightness of buildings. Simultaneously, we are more aware of the effects of indoor environment on people's health, productivity and general well-being. As a result, in recent decades there has been a rapid development of mechanical ventilation systems that allow both indoor air exchange and regulation of temperature and humidity. Because of high energy consumption of mechanical ventilation, natural ventilation becomes a great alternative when striving for better energy efficiency. However, due to the unpredictability and impact of the external environment, determining the efficiency of natural ventilation is difficult. One of the more established methods is the use of tracer gas, with which we measure natural air currents without interfering with the flow pattern itself. The purpose of this thesis is to review and compare methods based on the use of tracer gas and to determine their accuracy and suitability for practical implementation.
