Energetska analiza hladilnih naprav na ogljikov dioksid : diplomsko delo visokošolskega strokovnega študijskega programa 1. stopnje EnergetikaŠajnič, RokDandanes se klasični hladilni mediji, kot so freoni, umikajo iz uporabe oziroma so v hladilni tehniki že prepovedani, saj jih zamenjuje vse bolj priljubljen, ekonomsko in ekološko upravičen medij, ... ogljikov dioksid (CO2). Uporaba tega medija še ni tako razširjena zaradi specifičnosti izvedbe in prilagoditve hladilnih sistemov, zato se v večini primerov uporablja kot sekundarno hladilno sredstvo v kaskadnih sistemih. Da to dosežemo, moramo vse tlačno obremenjene elemente sistema prilagoditi posebnim zahtevam. V diplomskem delu sem se osredotočil na prednosti in slabosti CO2 sistemov, njihovo delovanje ter termične in fizikalne lastnosti CO2. Dejstvo je, da se danes o CO2 (v hladilstvu se uporablja oznaka R-744) veliko govori. Velika večina ljudi misli, da je R-744 škodljiv plin, a je v resnici zelo koristen in uporaben, če ga znamo pravilno izkoristiti. V nadaljevanju bo R-744 predstavljen kot zamenjava za obstoječe sisteme. Sam osebno menim, da se bo trend zelene miselnosti nadaljeval. Verjamem, da bo v prihodnjih nekaj letih uporaba freonov (F-plini) zakonsko omejena in kasneje tudi prepovedana.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Krško : [R.
