20.500.12556/RUL-160310 Pridobivanje vode iz atmosfere s higroskopskimi materiali na osnovi koncentracije toplotnega toka Atmospheric water harvesting using hygroscopic materials based on the heat flux concentration Povpraševanje po pitni vodi v določenih krajih sveta presega zmogljivost oskrbe zaradi različnih razlogov. Z uporabo higroskopskih materialov, ki izkoriščajo sončno energijo je možno oskrobvati zelo težko dostopna in sušna področja brez potrebe po elektriki. Z razvojem in nadgradnjo takih tehnologij postaja oskrba s pitno vodo vedno manjši problem. V delu smo predstavili ključne vplivne parametre pri zasnovi takih tehnologij, oblikovali matematični model in njegovo točnost primerjali z rezultati eksperimenta. Eksperiment smo izvedli v dveh stopnjah kjer smo primerjali vpliv uporabe polietilenske folije na proces desorpcije. Pri ustreznih okoliških parametrih in z uporabo polietilenske folije lahko izboljšamo hitrost in količino desorbirane vode. The demand for drinking water in certain parts of the world exceeds supply capacity due to various reasons. By using hygroscopic materials that harness solar energy, it is possible to supply very hard-to-reach and arid areas without the need for electricity. With the development and upgrading of such technologies, the problem of drinking water supply is becoming less significant. In our work, we presented the key influential parameters in the design of such technologies, developed a mathematical model, and compared its accuracy with experimental results. The experiment was conducted in two stages, where we compared the impact of using polyethylene film on the desorption process. With appropriate ambient parameters and the use of polyethylene film, the speed and amount of water desorbed from the hygroscopic material can be improved. voda desorpcija higroskopski materiali fokusiranje svetlobe absorberji matematični modeli water desorption hygroscopic materials light focusing absorbers mathematical models true false false [A.
