Abstract:Zaradi večjega ozaveščanja družbe o našem negativnem vplivu na naravo in iz tega izhajajočega segrevanja ozračja, strmimo k temu, da čim bolj učinkovito nadomestimo škodljive snovi z okolju prijaznejšimi. Enako se dogaja na področju ogrevanja in hlajenja s toplotnimi črpalkami. Nekoč alternativa za zmanjšanje negativnega vpliva na tanjšanje ozona, so danes hidrofluoroogljikovodiki pokazali, da niso okolju najbolj prijazna rešitev. Namreč njihov izpust in dolga življenjska doba v atmosferi vplivata na večanje efekta tople grede. Iz tega razloga je potreben razvoj novih in okolju prijaznejših hladilnih snovi, kot so hidrofluoroolefini. Simulacije, ki smo jih opravili za magistrsko nalogo so pokazale, da je uporaba novejših hladilnih snovi primerljiva z njihovimi predhodniki, a je na koncu potrebno pri zamenjavi hladilnih snovi upoštevati zraven termodinamskih lastnosti še okoljske in ekonomske dejavnike.

Title:Comparison of thermodynamic properties and the environmental impact for the fourth generation refrigerants
Abstract:Due to greater social awareness and our negative impact on nature and the resulting global warming, we strive to replace harmful substances with more environmentally friendly ones as effectively as possible. The same is happening in the field of heating and cooling with heat pumps. Once an alternative to reduce the negative impact on ozone depletion, today hydrofluorocarbons have shown that they are not the most environmentally friendly solution. Namely, their release and long lifespan in the atmosphere increase the greenhouse effect. For this reason, the development of new and more environmentally friendly refrigerants, such as hydrofluoroolefins, is needed. The simulations we performed for the master's thesis showed that the use of newer refrigerants is comparable to their predecessors, but in the end, it is necessary to consider environmental and economic factors in addition to thermodynamic properties when replacing refrigerants.
