Abstract
Pod utjecajem F-gas uredbe, radne tvari s visokim GWP-om postaju zabranjene u uporabi. Zbog toga se traže alternativne radne tvari s nižim GWP brojem kako bi se provela zamjena . U ovom radu istražene su komercijalno dostupne radne tvari HFC skupine sa srednjim GWP faktorom te je napravljen termodinamički proračun procesa s radnom tvari R-404A i zamjenskim radnim tvarima R-448A, R-449A i R-407F. Opisani su prednosti i nedostaci pri zamjeni radne tvari kao i postupak same zamjene. Navedene su komponente sustava s opisom i ulogom te dijelovi koji zahtijevaju zamjenu jer nisu kompatibilni s novom radnom tvari.
Abstract (english)
Under the influence of F-gas regulation, refrigerants with high GWP factor are becoming banned to use. Therefore, alternative refrigerants with lower GWP factor are sought for retrofitting. In this study it is looked into commercially available HFC refrigerants with medium GWP factor and thermodynamic calculation of process with refrigerant R-404A and its retrofits R-448A, R-449A and R-407F is presented. Advantages and disadvantages are described for each refrigerant as well as the procedure of retrofitting. Components of a system are listed with description and role as well as parts that require replacement because they are not compatible with a new refrigerant.
