Abstract
U radu je prikazano dvo-stupanjsko kaskadno rashladno postrojenje, koje kao zadanu radnu tvar koristi ekološki neprihvatljivu tvar R-22. U skorašnje vrijeme, znanstvenici iz svih grana znanosti rade na rješavanju problema onečišćenja okoliša i globalnog zatopljenja. Stoga, imajući u vidu ekološke značajke radne tvari, te i samu iskoristivost, odabrana su dva nova radna medija kao potencijalna zamjena zadanoj radnoj tvari. Postavljanjem matematičkog modela rashladnog proces, te korištenjem računalnog softvera „Engineering Equation Solver“ (EES), dobivene su veličine stanja kao i sama rješenja zadanog sustava za zadanu radnu tvar i za potencijalne zamjenske radne tvari. Cijeli matematički model i sami proračuni su postavljeni na osnovi zadanih radnih parametara sustava, i pod pretpostavkom da su zadani procesi idealni.. Usporedbom rezultata, te usporedbom kemijskih i termodinamičkih svojstava radnih tvari, utvrđeno je da ekološki najprihvatljivija tvar nije i optimalna s termodinamičkog stajališta za ovo rashladno postrojenje.
Abstract (english)
The paper presents a two-stage cascade refrigeration plant, which uses the environmentally-nonacceptable R-22 as the default working substance. In modern times, scientists from all branches of science are working on the solving of problem of environmental pollution and global warming. Therefore, given the ecological characteristics of the working substance and the usability itself, two new working substances were selected as a potential replacement of the default working substance By creating a mathematical model for the cooling process and using the Engineering Equation Solver (EES) software, the states of the system, and the results of the system itself were acquired for default substance, and for the potential replacements. The entire mathematical model and the calculations themselves are based on the default working parameters of the system, and considering the default processes to be ideal. By comparing the results and comparing the chemical and thermodynamical properties of the substances, it was found that the most environmentally friendly substance is not the optimal, from a thermodynamic point of view, for this refrigeration plant.
