Hlajenje in klimatizacija potniškega vagona - kasnejša vgradnja : specialistična nalogaKrošelj, JurijZaradi zagotavljanja čedalje višjega komforta prevoza potnikov, postaja tudi v SŽ vedno bolj zanimiv projekt adaptacije - naknadne vgradnje klima naprav v obstoječ vozni park potniških vagonov ... Slovenskih železnic. Vgradnja klima naprave je smotrna le v vagone tipa Z 1 serije A, B in Y, ki niso starejši od 15 let in so moderne konstrukcije, ustrezajo RIC predpisom in so grajeni za hitrosti do 200 km/h. Vgradnja klima naprave, je predvidena v obdobnem popravilu - investicijsko popravilo, kar pomeni, da predstavlja popravilo znatno investicijo v osnovno sredstvo. Cilj je ohranjanje vrednosti in funkcionalnosti vozila. V vagonih tip Z1 je vgrajeno toplozračno ogrevanje. To pomeni, da lahko iste kanale koristimo za klimatizacijo vagona in zmanjšamo stroške predvidenih del. Nadgradimo le dodatne kanale za vpih ohlajenega zraka v zgornjo cono prostora za potnike, ki jih povežemo z obstoječim spodnjim razvodom. Narediti je potrebno izračun toplotnih obremenitev, določiti potrebno hladilno moč, in izbrati elemente klimatizacijskega sistema. Vgradnja klima naprave je predvidena v podvozje vagona. Pomembno je, vgraditi in izbrati takšno konstrukcijo hladilnega stroja in njegovih komponent, ki bo omogočala uporabo ekološko sprejemljivega hladila. Imeti mora zadovoljive termodinamične lastnosti in zagotavljati zanesljivost in ekonomičnost v pogonu. Tako opremljen vagon bo imel bistveno izboljšano potovalno udobje potnikov.Type of material - specialist thesisPublication and manufacture - Maribor : [J.
