Abstract [eng] |
Chemicals which are released into indoor air from structural materials, indoor heating, interior fittings and buildings cause many health problems. Due to this reason indoor air quality needs as much thought as outdoor air quality has nowadays. However, it is also important to use such measures that do not affect human health, ecosystem, climate change or resources during its lifetime. In this master thesis an equipment intended to clean indoor air is examined. Comparative environmental assessment was performed as well. For these reasons comparative life cycle assessment was carried out on three air treatment technologies – activated carbon with F7 filter, non – thermal plasma and a prototype unit designed for air treatment constructed in Kaunas university of technology. The normalized results showed that when comparing three different air treatment technologies, activated carbon and F7 filter has 2 times higher impact on human health than the prototype unit. The effect of non–thermal plasma is 5 times higher than the prototype unit has on the same impact category. Whereas the effect of activated carbon and F7 filter on the climate change is 2,3 times higher than the prototype unit, where the effect of non–thermal plasma on the same category is 5 times higher than on the prototype unit. Comparative environmental assessment was carried out on three different air treatment filters – activated carbon and F7 filter, non – thermal plasma and prototype unit. It was determined that a prototype unit has a lower environmental impact than activated carbon and F7 filter and non – thermal plasma. |
