Parametrični model učinkovitosti solarnega hladilnega sistema : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoOzmec, PrimožHlajenje trenutno predstavlja velik delež porabe energije na svetu, kar je posledica globalnega segrevanja, širitve grajenega okolja in dviga standarda bivalnega ugodja. Poleti, ko so potrebe po ... hlajenju največje in je na voljo največ sončnega sevanja, je smiselno uporabiti toplotno gnani hladilni sistem. V diplomski nalogi je glavni predmet proučevanja solarni hladilni sistem, ki je vgrajen v energijsko samozadostno stavbo Laboratorija za okoljske tehnologije v zgradbah, imenovano Celica. V programu Excel smo izdelali numerične modele za analizo delovanja posameznih komponent solarnega hladilnega sistema in rezultate numeričnega izračuna validirali s pomočjo meritev. Ugotovili smo, da lahko fotonapetostne celice uporabimo kot merilnike sončnega sevanja. Izračunali smo dnevno učinkovitost sprejemnikov sončne energije, ki je ob pogojih meritev znašala od 0,27 do 0,31. Validirali smo spreminjanje temperature v hranilniku toplote in ugotovili, da so toplotne izgube manjše od dovoljenih po Direktivi o okoljski primerni zasnovi 814/2013. Z numeričnim modelom za izračun delovanja solarnega hladilnega sistema smo izračunali dnevni COP hladilne naprave, ki je znašal od 0,72 do 0,74. Poleg predlog v Excelu, smo pripravili nabor vprašanj za laboratorijske vaje v okviru predmetov Laboratorija za okoljske tehnologije v zgradbah.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [P.
