Okoljski monitoring in merilna oprema

Novak, Anton (author), Begeš, Gaber (mentor)

Diplomsko delo predstavlja pregled literature in pripravo merilnega sistema za merjenje okoljskih parametrov v zaprtih prostorih za namene raziskave povezave počutja in okoljskih parametrov. Na podlagi literature in že narejenih raziskav so najbolj vplivne veličine, ki vplivajo na človeka v zaprtem prostoru temperatura, vlaga, zračni tlak, osvetljenost, glasnost, VOC (Hlapljive organske spojine, ang. volatile organic compounds), prašni delci (PM) ter plini, posebej CO2, CO, NOx, SO2 in O3. Zaradi narave parametrov, za merilni sistem ne zadostuje ena sama naprava ampak je potrebno več naprav razporejenih po prostoru. Ker na naše zaznavanje notranjega okolja močno vpliva zunanji zrak, je pomembna tudi zunanja enota. Za zgoraj omenjene veličine je bil opravljen pregled trga razpoložljivih senzorjev. Pri izbiri je upoštevan tako tehnični vidik kot dostopnostni vidik. Sistem je pred uporabo potrebno tudi ustrezno ovrednotiti in kalibrirati. Posebej pomembna je uskladitev enot sistema, da so merjene vrednosti med seboj enotne, saj le tako sistem podaja ustrezno informacijo o okolju. Narejen je pregled standardov, ki se nanašajo na merjenje opazovanih veličin in na kalibracijo merilnikov, ter je v skladu s tem in z zahtevami sistema podan koncept kalibracije oziroma vrednotenja rezultatov.

Abstract

This thesis presents a literature review and the development of a measurement system for indoor environmental parameters for the purpose of investigating the relationship between sensation and environmental parameters. Based on the literature and the research carried out, the most influential variables that affect people in an indoor environment are temperature, humidity, air pressure, illuminance, noise, VOC (Volatile Organic Compounds), PM (Particulate Matter) and gases, especially CO2, CO, NOx, SO2 and O3. Due to the nature of the parameters, it is not sufficient to have a single device for the measurement system, but rather a number of devices distributed around the room. As the sensing of the indoor environment is strongly influenced by the outdoor air, an outdoor unit is also important. For the above mentioned quantities, a review of the market for field deployable sensors has been carried out. The choice is based on both technical and accessibility aspects. The system must also be properly evaluated and calibrated before use. It is particularly important to harmonise the units of the system so that the measured values are uniform with each unit, as this is the only way to ensure that the system provides relevant information about the environment. A review of the standards relating to the measurement of these observables and to the calibration of the meters is made and, in accordance with that and the requirements of the system, a concept is given for calibration or evaluation of the results.
