Vpliv dnevno-sevalnih materialov na kondenzacijo pare pri temperaturi okolice

Pogačnik, Žan (author), Poredoš, Primož (mentor)

Trajnosten dostop do pitne vode je eden izmed največjih inženirskih izzivov v zadnjem času. Vodna para v ozračju je dobra rešitev zaradi svoje velike količine in univerzalne razpoložljivosti. V tem delu bomo predstavili vpliv dnevno sevalnih materialov na kondenzacijo vodne pare in posledično pridobivanje vode z izvedbo eksperimenta, kjer bomo uporabili eno referenčno aluminijasto ploščo in eno z dodanim dnevno sevalnim materialom. Ugotovili smo, da imajo dnevno sevalni materiali kar velik vpliv na kondenzacijo. Predvsem ponoči je pridobivanje vode zelo dobro.

• Title: The influence of daytime-radiative materials on steam condensation at ambient temperature

Abstract

Sustainable access to drinking water is one of the greatest engineering challenges in recent times. Water vapor in the atmosphere is a promising solution due to its abundance and universal availability. In this work, we present the influence of daytime-radiative materials on water vapor condensation and, consequently, water harvesting, by conducting an experiment using one reference aluminium plate and one plate with an added daytime-radiative material. We found that daytime-radiative materials have a significant effect on condensation. Water harvesting is especially effective during the night.
