Določevanje učinkovitosti lokalnega prezračevanja po metodi zmanjševanja

Perkovič, Jan (author), Prek, Matjaž (mentor)

V diplomski nalogi sem pokazal, kako lahko določimo učinkovitost prezračevanja v praksi. Prikazal sem merilno progo, merilno opremo ter uporabo sledilnega plina CO2. Prikazal sem potek meritve po metodi z zmanjševanjem koncentracije sledilnega plina z dovajanjem plina v dovodno cev prezračevalnega sistema. Za vrednotenje meritev sem uporabili program Microsoft Excel, v katerem sem izdelal program za izračune učinkovitosti izmenjave zraka, srednje starosti zraka ter posledično same učinkovitosti prezračevanja.

• Title: Determination of effectiveness of ventilation by decay method

Abstract

In my graduate thesis I show how the effectiveness of ventilation system is measured in practice. I displayed the measurement course, measurement equipment and the use of CO2 as tracer gas. I explained how we preform decay method by supplying tracer gas in inlet hose of ventilation system. I used Microsoft Excel, where I programed the code to evaluate and graph our results. I determined local mean age of air, air exchange efficiency and ventilation efficiency.
