Vpliv hlajenja z dnevno sevalnimi materiali na adsorpcijo vode iz zraka

Lesar, Jakob (author), Poredoš, Primož (mentor), Ristić, Alenka (comentor)

Adsorpcija vode iz zraka je proces, ki postaja vse bolj aktualen v današnjem svetu. Ker gre za počasen proces si želimo izboljšati kinetiko in količino adsorbirane vode. Za poskus rešitve tega problema sem si izbral dnevno sevalne materiale. Z meritvami sem začel v laboratoriju, da sem pridobil neke osnovne vrednosti. Meritve sem nadaljeval na prostem. Učinkovitost DSM-jev je pogojena z jasnostjo neba, saj je glavni cilj DSM-jev ohladiti površino pod temperaturo ambienta. V primeru jasnega neba in visokih RH pričakujemo do 40% več adsorbirane vode, kot če jih ne bi uporabljali.

• Title: Impact of cooling with diurnal radiative materials on water adsorption from the air

Abstract

Adsorption of water from the air is a process that is becoming increasingly relevant in today's world. Since it is a slow process, we want to improve the kinetics and the amount of adsorbed water. To try to solve this problem, I chose diurnal radiative materials. I started with the measurements in the laboratory to obtain some basic data. I continued the measurements outdoors. The efficiency of DSMs is conditioned by the clarity of the sky, since the main goal of DSMs is to cool the surface below the ambient temperature. In the case of clear skies and high RH, we expect up to 40% more adsorbed water, compared to not using them.
