Ustreznost kondenzacijskega sušenja lesa v manjših lesnih obratih : diplomsko delo - univerzitetni študij = Suitability of dehumidifying drying for smaller joiner workshops : graduation thesis - university studiesTomazin, SimonZa ovrednotenje prilagodljivosti in ustreznosti kondenzacijskega sušenja za manjše lesne obrate smo sušili smrekovino, bukovino in hrastovino iz svežega stanja do končne vlažnosti 10 %. Primerjali ... smo čase in hitrosti sušenja, kakovost posušenega lesa, vlažnostne gradiente in sušilne napetosti ter porabo energije. Pri smrekovini smo na začetku sušenja zaznali vlažnostni gradient okoli 3,5 %/cm, ki se je nato še nekoliko povečal, na koncu pa padel do sprejemljive vrednosti. Začetne vlažnosti pri bukovini so bile različne med beljavo in rdečim srcem. Vlažnostni gradient je bil na začetku več kot 5 %/cm, proti koncu sušenja pa je bil minimalen. Med sušenjem so se pojavile manjše razpoke, ki pa niso vplivale na končno kakovost osušenega lesa. Začetni prerez hrastovine je pokazal homogeno razporeditev vlažnosti, vendar se je po začetku sušenja vlažnostni gradient močno povečal, kar je vodilo v notranje razpoke in satavost; po koncu sušenja pa je les ostal zaskorjen. Najkrajši čas sušenja smo dosegli pri smrekovini (333h), najdlje pa smo sušili hrastovino (2617h). Za 1m3 sušenja smrekovine smo potrošili 533 kWh energije, za isto količino hrastovine pa kar 4481 kWh električne energije.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
