Prezračevanje spalnice na podlagi meritev onesnažila ogljikovega dioksida v zraku

JERŠIN, KLEMEN (author), Kos, Anton (mentor)

Današnji prezračevalni sistemi morajo izpolnjevati predpise in zahtevne standarde. Sodobni načini bivanja z novimi smernicami, ki temeljijo na energetski učinkovitosti so pripeljale do iskanja kompromisov med ustrezno mikroklimo v bivalnih okoljih in učinkovitostjo prezračevalnih sistemov. Načrtovanje prezračevalnih sistemov je danes interdisciplinarna naloga, ki zajema ogromno pogojev. V nalogi sem se osredotočil na prezračevalni sistem, ki temelji na vrednostih CO2 onesnažila v prostoru. Za nalogo sem izdelal merilni sistem, ki je meril vrednosti CO2 v opazovani sobi, v kateri je spala opazovana oseba. Isti merilni sistem sem uporabil tudi pri merjenju vrednosti CO2, ko je v isti sobi deloval moj mehanični prezračevalni sistem. Merilni sistem sem umestil v krmilni del prezračevalnega sistema, ki je zbrane podatke preko uporabniškega vmesnika obdelal v realnem času. Krmilni del sistem je na podlagi v naprej določenih vrednosti onesnažila CO2 v opazovani sobi krmilil mehanični del prezračevalne naprave, ki sem ga umestil v sobo. Prenos podatkov je potekal po žičnih in brezžičnih komunikacijskih poteh. V nadaljevanju naloge sem izvedel poskus ustreznosti delovanja izdelanega prezračevalnega sistema. Z fiziološkimi meritvami sem ugotavljal kakovost spanja in nivo kisika v krvi opazovane osebe v opazovani sobi. Poskus je potekal z naravnim in mehaničnim prezračevanjem. Na koncu naloge sem primerjal ugotovitve in izpostavil prednosti in slabosti obeh sistemov in izpostavil ugotovitve veličine, ki sem jih pri načrtovanju mehaničnega prezračevanja izpustil.

• Title: Bedroom ventilation based on measurements of the carbon dioxide pollutant in the air

Abstract

Today's ventilation systems must meet regulations and demanding standards. Modern ways of living with new energy efficiency guidelines have led to the search for compromises between the appropriate microclimate in living environments and the efficiency of ventilation systems. Designing ventilation systems today is an interdisciplinary task that covers a wide range of conditions. In the assignment, I focused on the ventilation system based on the values of CO2 pollution in the room. I placed the measuring system in the control part of the ventilation system, which processed the collected data in real time via the user interface. The control part of the system controlled the mechanical part of the ventilation device, which I placed in the room, based on the predetermined values of CO2 pollution in the observed room. Data transfer took place via wired and wireless connections. In the continuation of the task, I conducted an experiment on the adequacy of the functioning of the manufactured ventilation system. I used physiological measurements to determine the quality of sleep and the level of oxygen in the blood of the observed person in the observed room. The experiment was conducted with natural and mechanical ventilation. At the end of the task, I compared the findings and pointed out the advantages and disadvantages of both systems and pointed out the findings of greatness that I omitted when planning the mechanical ventilation.
