20.500.12556/DKUM-14721 HLAJENJE PETROMATA COOLING THE PETROMAT V diplomskem delu je opisano hlajenje petromata, ki služi za hlajenje elektronskih komponent v samem črpalnem terminalu. Pogoj za izdelavo takšne naloge je bil, da smo izdelali logično krmilje na osnovi katerega bo avtomatiziran proces hlajenja v črpalnem terminalu. Pri izdelavi krmilja smo strmeli k temu, da bo projekt izdelan kvalitetno in zanesljivo. Eden od elementov sistema je krmilnik proizvajalca Mitshubishi ALPHA 2, ki je bil izbran glede na zahteve projekta. Na podlagi tega smo izdelali logično krmilje v programskem okolju AL-PCS/WIN-E. V nadaljevanju so natančno predstavljeni in opisani krmilniki ALPHA proizvajalca Mitsubishi ter načini programiranja krmilnikov ALPHA. Za pretvarjanje izmerjene vrednosti (temperatura) v električno napetost smo na podlagi zahtev izbrali pretvornik Mitsubishi ALPHA 2. Podrobneje si bomo ogledali tudi ozadje Peltierjevega pojava, ki ga srečamo v vsakdanji praksi. Za merjenje temperature v črpalnem terminalu je na osnovi zahtev bilo izbrano ustrezno temperaturno tipalo Pt 100. This diploma describes the cooling system of a petromat used for cooling the electronic components in a pumping terminal. The idea behind this study was to elaborate a logical control system which will serve as a basis for the automated cooling of the pump terminal. When manufacturing the control system we strived at achieving quality and reliability. One of the elements of the system is the Mitsubishi ALPHA controller which was selected according to the demands of the project. On this basis, we designed the logical steering in the programming environment AL-PCS/WIN-E. Further in this work, controllers ALPHA by the manufacturer Mitsubishi and ways of programming the ALPHA controllers are precisely presented and described. On the basis of requirements we selected Mitsubishi ALPHA 2 converter to convert the measured value (temperature) to electric voltage. The background of Peltier phenomenon which we encounter in everyday practice is presented in more detail. For measuring the temperature in the pump terminal, the appropriate temperature sensor Pt 100 was selected according to requirements. avtomatizacija regulacija temperature krmilnik Mitsubishi ALPHA 2 pretvornik Mitsubishi AL2-2PT-ADP temperaturno tipalo Pt 100 Peltierjev element automatisation temperature control controller Mitsubishi ALPHA 2 converter Mitsubishi AL2-2PT-ADP temperature sensor Pt 100 Peltier component true true false [M.
