20.500.12556/DKUM-16563 TERMODINAMIČNI PRERAČUN VIJAČNEGA IN BATNEGA KOMPRESORJA A THERMODINAMICAL CALCULATION OF SCREW AND PISTON COMPRESSORS Diplomsko delo obravnava termodinamični pregled procesa kompresije zraka v vijačnem in batnem kompresorju. Izračunane veličine so osnovane na izmerjenih vrednostih skozi večletno obdobje obratovanja in kažejo realno sliko delovanja takšnih kompresorjev. V termodinamičnem procesu pri obeh tipih kompresorjev prihaja do manjše razlike, ki pa je v prid batnemu kompresorju. Kljub temu zaključujem, da zaradi konstrukcijskih razlik, ki jih imata obravnavana primera, vijačni kompresor vseeno predstavlja boljšo izbiro za obravnavano aplikacijo. This diploma work deals with thermodynamic process of air compression in screw and comparable piston compressors. The calculated results are based on measured values through years of operating and show a realistic view of compressor performance. Focusing strictly on thermodynamical process of compression there is a slight variation between the two types, showing that the piston compressor has a better yield. However, because of the different construction solutions between the two types, I conclude that the screw compressor represents a better choice for such application. termodinamika vijačni kompresor batni kompresor idealni kompresor dizajn vijačnice politropa izkoristek kompresije IA zrak NEK (Nuklearna elektrarna Krško) termodynamics screw compressor piston compressor ideal compressor screw helix design polytropic process efficiency of compression IA air Krško Nuclear power plant true true false [B.
