Poboljšanje mikroklime u kabini poljoprivrednih mašina primenom lokalizovane distribucije vazduha
Univerzitet u Novom Sadu, Fakultet tehničkih nauka
Sažetak
Samohodna poljoprivredna mehanizacija se na našim prostorima najvećim delom eksploatiše u tzv. toplom delu godine. U tim uslovima, zbog sunčevog zračenja i drugih izvora toplote, kabina rukovaoca mašinom može postati prostor koji je krajnje nepogodan za boravak i rad čoveka. Iz tog razloga, važan aspekt ergonomije rada u kabini mobilne poljoprivredne mehanizacije jeste stvaranje i održavanje pogodne mikroklime. Konvencionalni pristup analizi mikroklimatskih uslova u kabini zasniva se na posmatranju prostora kabine kao homogenog. Takođe i standardi i norme kojima se propisuju mikroklimatski uslovi u zatvorenom prostoru preporučuju što manju nehomogenost. U realnosti, uslovi su obično izrazito nehomogeni i promenljivi u vremenu, a čovekovo telo zauzima samo manji deo zapremine unutrašnjosti kabine i nema mnogo mogućnosti za promenu položaja. Pored toga, pojedini delovi čovekovog tela imaju različitu toplotnu osetljivost i različito utiču na ukupni topotni osećaj i toplotni komfor, što je u ovom radu iskorišćeno kao osnova za istraživanje u pravcu generisanja kontrolisane neuniformnosti mikroklimatskih parametara lokalizovanom distribucijom kondicioniranog vazduha u traktorskoj kabini.
