Abstract
Primerjali smo stroške konvencionalnega in kondenzacijskega sušenja lesa. Stroške konvencionalnega sušenja smo izračunali s CAE računalniškim modelom, stroške kondenzacijskega sušenja pa smo ocenili z analizo konkretno izvedenega postopka. Izračun smo naredili na primeru sušenja bukovega lesa (Fagus Sylvatica L.), debeline 50 mm. Z oceno in primerjavo stroškov smo predvideli lesno vlažnost, pri kateri je prehod med obema postopkoma sušenja optimalen. Ugotovili smo prednosti začetnega sušenja svežega lesa po kondenzacijskem načinu in nato dosušitev do končne vlažnosti po konvencionalnem postopku. Optimalni prehod med obema načinoma sušenja smo dosegli pri lesni vlažnosti 35,1 %. Večjih prihrankov s kombiniranjem sušenja nismo potrdili, vzrok pa je velika razlika med cenama električne in toplotne energije.

Title:Optimal combination of kiln and dehumidification drying procedure : B. Sc. thesis
Abstract:
The costs of kiln and dehumidification drying of wood were compared. The kiln drying costs were calculated by the CAE computer model, while the dehumidification drying costs assessed by an analysis of the procedure made. Our calculation was done on the basis of the 50 mm thick beech wood drying (Fagus Sylvatica L.). The wood moisture was foreseen by assessing and comparing the costs, according to the optimal drying transfer of both procedures. Advantages of the initial dehumidification drying of fresh wood and then drying to the final moisture with the kiln drying procedure were established. The optimal drying transfer of both procedures was achieved at 35.1 % of wood moisture. We were not able to confirm larger savings by drying combinations because of the huge difference in prices between the electrical and thermal energy.

Keywords:wood, drying, kiln, dehumidification, costs
