Salt-solution-infused thin-film condenser for simultaneous anti-frost and solar-assisted atmospheric water harvesting

Frost is undesirable in many applications. Previous methods of defrosting are either energy intensive or ineffective the long term. Meanwhile, frost a valuable freshwater source whose production delayed due to solid state and lengthy accumulation frost. Here, salt-solution-infused thin-film condenser (SSTFC) proposed for anti-frost at low consumption simultaneous production. The SSTFC composed highly permeable lower layer salt solution infusion an ultrathin hydrophobic top constraining infused incorporating condensed vapor into underlying various temperatures. gradually diluted can be passively transported regeneration by solar energy. regenerated pumped back continuous operation system. Energy saved >50% compared conventional methods.
