20.500.12556/RUL-172899 Načrtovanje prenove kondenzacijske sušilnice v manjšem lesnopredelovalnem podjetju Planning the renovation of a dehumidification dryer in a small wood-processing company V diplomskem delu je obravnavana prenova kondenzacijske sušilnice v manjšem lesnopredelovalnem podjetju. Analizirano je bilo obstoječe stanje sušilne komore in kondenzacijskega agregata, izdelani so bili programi sušenja za smreko, bukev in hrast v različnih debelinah ter opravljeni izračuni porabe energije, potrebne moči agregata in stroškov sušenja. Rezultati so pokazali, da je kondenzacijsko sušenje najbolj učinkovito pri tanjših sortimentih in višjih začetnih vlažnostih lesa, pri čemer je smrekovina energijsko in stroškovno najbolj ugodna. Poraba energije in stroški se z debelino sortimentov občutno povečujejo, najzahtevnejše pa je sušenje hrastovine. Ugotovljeno je bilo, da so toplotne izgube največje v zimskem času, kar povečuje stroške obratovanja. Na osnovi izračunov je bila kot optimalna rešitev izbrana vgradnja kondenzacijskega agregata z nazivno močjo približno 5 kW ter učinkovitejših ventilatorjev, kar omogoča zmanjšanje porabe energije, enakomernejše kroženje zraka in izboljšano kakovost posušenega lesa. The work deals with the renovation of a dehumidification dryer in a small wood processing company. The actual condition of the drying kiln and the dehumidification unit was analysed, drying schedules for spruce, beech and oak of different thicknesses were developed and calculations of the energy consumption, the required unit power, and the drying costs were carried out. The results show that dehumidification drying is most efficient with thinner assortments and higher initial moisture contents, with spruce proving to be the most energy and cost-efficient wood species. Energy consumption and costs increase significantly with wood thickness, with oak being the most costly to dry. It was found that heat losses are highest in winter, which leads to higher operating costs. Based on the analyses, the optimal solution was determined to be the installation of a dehumidification unit with a nominal power of around 5 kW in combination with more efficient fans, which would enable lower energy consumption, a more even air flow through the stack and a better quality of the dried wood. kondenzacijsko sušenje lesa kondenzacijski agregat prenova sušilnice poraba energije stroški sušenja dehumidification drying dehumidification unit dryer renovation energy consumption drying costs true false false [A.
